Adaptability
Solar power has never been so easy
Options and choices
In general we use two basic options for mounting rigid solar panels – one gets you up and over the canvas, and the other is a bit leaner. We then adapt the basic concept to the boat in question.
You can read more about these basic models in our article in Marine Fabricator magazine . This will give you a good idea where to start in planning your solar panel project.
Please also see our page of advice and FAQs on adding solar panels in seven easy steps.
Once you have a basic mounting option in mind, you can choose what Gemini Marine Products you want to use to execute the build. Real people build solar panel mounts with our hardware all the time – see a selection of their recommendations below.
Option 1: Low and lean
We designed our saddle-type post and fork mounts with solar panels in mind. They give you easy, secure mounts for a solar panel frame that won’t draw attention to itself.
The saddle fittings bolt onto the top of the frame through the canvas of your bimini top or dodger. Rails running fore and aft create the base, and athwartship rails can augment the frame if needed. The entire installation can be made from off-the-shelf materials on the boat.
This option puts the entire rack up on the roof and largely hidden from view.
Option 2: Up and over
Alternatively you can use our sliding or split side mounts to create exterior side rails between your bimini’s end frames. Paired with a set of side-to-side bent rails, they go up and over the top to create the mounting platform.
This method does not touch the canvas and can be retrofitted without any fabric modifications. It provides good clearance and additional features such as a protective crash bar (think boom).

Adding Solar Power to a Sailboat
- By Emily Fagan
- Updated: October 18, 2019
During our nearly four-year cruise of Mexico, my husband, Mark, and I lived almost exclusively on 555 watts of solar power charging a 640-amp-hour house battery bank. We anchored out virtually every night aboard our 2008 Hunter 44DS, Groovy , and relied on the sun for power. During one 10-week stretch, while we waited for a replacement engine alternator to arrive, our boat’s solar panels were our sole source of power. We had no backup charging system to turn to, and yet we lived and sailed comfortably the entire time. Mounting solar panels on a sailboat was not difficult, but a few key decisions made a huge difference in how effective our panels were.
A solar-power installation on a sailboat is made up of two independent systems: one system to charge the batteries, and another system to provide 120-volt AC power for household appliances. In the charging system, the solar panels convert sunlight into electrical current and deliver it to the batteries via a solar charge controller. Similar to a voltage regulator, the charge controller acts as a gatekeeper to protect the batteries from receiving more current than they need as they are being charged. In the AC power system, an inverter or inverter/charger converts the 12-volt DC power in the battery into 120 volts AC whenever it is turned on.
Panel Positioning and Wiring Considerations
One of the biggest challenges for sailors installing solar power on a sailboat is finding a place on the boat where the panels will be shaded as little as possible. Just a few square inches of shade on one panel can render that panel all but inoperable. Unfortunately, between the mast, radome, spreaders and boom, shadows cross the deck all day long, especially as the boat swings back and forth at anchor.
What’s worse, if the panels are wired in series rather than in parallel, this little bit of shade can shut down the entire solar-panel array. When we installed solar power on Groovy , we had already lived exclusively on solar power in an RV for over two years. Our RV solar panels had been wired in series, and we had witnessed the array shutting down current production when just half of one panel was shaded.
Choosing whether to wire the panels in series or parallel on a boat affects the wire gauge required, which is why many solar-power installers lean toward wiring the panels in series. Panels wired in series can be wired all the way to the solar charge controller with a thinner-gauge wire than those wired in parallel. This is because the voltage of panels wired in series is additive, while the current remains constant, so the current flowing is just that of a single panel. In contrast, the current flowing from panels that are wired in parallel is additive, while the voltage across them is not. This means that in a parallel installation, the current going to the charge controller is several times higher and requires much thicker cable to avoid any voltage loss over the length of the wire.
Not only is thinner-gauge wire less expensive, but it is also more supple and easier to work with, making the job of snaking it in and around various crevices in the boat and connecting it to the solar charge controller much less of a struggle. Thus the choice between series and parallel wiring boils down to a trade-off between system performance, expense and ease of solar system installation.
Luckily, the size of the wire can be reduced if higher-voltage solar panels are chosen. Since watts are determined by multiplying volts by amps, a higher-voltage panel that generates the same watts as a lower-voltage panel will produce less current. Therefore, selecting nominal 24-volt panels instead of 12-volt panels allows for the use of thinner wire sizes no matter how they are wired.
Our Marine Solar Panel Design Choices
In our installation, we decided to mount three 185-watt, 24-volt (nominal) Kyocera solar panels high above the cockpit, well aft of the boom, as far away as possible from potential shade. Our Hunter came with a big, solid stainless-steel arch, and we turned to Alejandro Ulloa, a brilliant metal fabricator at Baja Naval Boatyard in Ensenada, Mexico, to build a polished stainless-steel solar-panel arch extension onto the existing structure. He designed the arch extension with integrated telescoping davits to hoist our dinghy as well as support the solar panels. These davits were strong enough — and the lines and blocks had enough purchase — that either of us could lift our light Porta-Bote dinghy with its 6-horsepower outboard without a winch.
We spaced the panels about a half-inch apart and wired them in parallel. Using two twin-lead wires, we snaked the three positive leads and one common ground down through the inside of the arch tubes so they wouldn’t be visible, and placed wire loom over the exposed wires under the panels.
The junction points for the three parallel panels were on positive and negative bus bars inside a combiner box, all mounted in a cockpit lazarette. Inside the combiner box, we installed three breakers, one for each panel. This gave us the ability to shut off any or all of the panels if we needed to (we never did).
We mounted a Xantrex solar charge controller (model XW MPPT 60-150) in a hanging locker, as close to the batteries as possible, in a spot where it was easy to monitor and program. We ran twin-lead wire from the combiner box to the charge controller and from there to the batteries.
Our boat came with three new 12-volt Mastervolt 4D AGM house batteries, all wired in parallel, for a total of 480 amp-hours of capacity. We wanted a bigger house battery bank, and because it is best for the age, type and size of the batteries to be matched, we added a fourth new Mastervolt 4D AGM house battery, which brought our total to 640 amp-hours. Our batteries were installed at the lowest point in the hull, below the floorboards, and they ran the length of the saloon, from just forward of the companionway stairs to just aft of the V-berth stateroom door.
The best way to charge a bank of batteries that are wired in parallel is to span the entire battery bank with the leads coming from the charge controller. We did this by connecting the positive lead from the charge controller to the positive terminal of the first battery in the bank, and the negative lead from the charge controller to the negative terminal of the last battery. By spanning the entire bank, the batteries were charged equally rather than having the charging current focused on just the first battery in the bank.
We feel that AGM batteries are superior to wet cell (flooded) batteries because they can be installed in any orientation, don’t require maintenance, can’t spill (even in a capsize), and charge more quickly. Our Mastervolt batteries, like almost all AGM batteries on the market, are dual-purpose, combining the very different characteristics of both deep-cycle and start batteries. Our batteries work well, but if we were doing an installation from scratch today, we would consider the new Trojan Reliant AGM batteries. These batteries are engineered strictly for deep-cycle use and have been optimized to provide consistent current and maximize battery life.
Our boat came with a Xantrex Freedom 2,500-watt inverter/charger wired into the boat’s AC wiring system with a transfer switch. The inverter/charger performed two functions. While the boat was disconnected from shore power, it converted the batteries’ 12-volt DC power into 120-volt AC power, allowing us to operate 120-volt appliances, like our microwave. When the boat was connected to shore power, it charged the batteries.
Because this inverter/charger was a modified-sine-wave inverter, mimicking AC current with a stair-stepped square wave, we also had a 600-watt pure-sine-wave inverter to power our potentially more sensitive electronic devices. We chose Exeltech because its inverters produce an electrical signal that is clean enough to power medical equipment, and they are NASA’s choice for both the Russian and American sides of the International Space Station. For simplicity, rather than wiring the inverter into the cabin’s AC wiring, we plugged ordinary household power strips into the AC outlets on the inverter and plugged our appliances into the power strips. Like the charge controller, the inverter must be located as close to the batteries as possible. Ours was under a settee.
Shade’s Impact on Sailboat Solar Panels
Once our solar installation was completed on our sailboat, we closely observed the effects of shade on our solar-panel array. We were often anchored in an orientation that put the panels in full sun. Just as often, however, we were angled in such a way that shade from the mast and boom covered portions of our panels. It was fascinating to monitor the solar charge controller’s LCD display whenever the sun was forward of the beam — the current from the panels to the batteries fluctuated up and down as we swung at anchor.
Taking notes one morning, we noticed that the charging current was repeatedly creeping up and down between 9.5 and 24.5 amps as the boat moved to and fro. When the entire solar-panel array was in full sun, it generated 24.5 amps of current. When we moved so the mast shaded a portion of one panel, the array generated 15 amps. When it shaded portions of two panels and only one was in full sun, the array produced just 9.5 amps. Of course, it would have been preferable to see a steady 24.5 amps all morning, but this sure beat watching the current drop to zero whenever a shadow crossed a panel.
We discovered that shade makes a huge impact while sailing, too. Surprisingly, it is far worse to have the panels shaded by the sails than to have the panels in full sun but tilted away from its direct rays. One afternoon, we noticed that while we were on a tack that tilted the panels away from the sun, they generated 24.5 amps of current, whereas on a tack where the panels were tilted toward the sun but two of the three were partially shaded by the sails, the current dropped to a mere 10 amps.
Reflections On Our Solar Panel Installation
A wonderful and surprising side benefit of our large solar panels and arch system was that the setup created fabulous shade over the jumpseats at the stern end of the cockpit. Our metal fabricator, Alejandro, placed a support strut at hand-holding height, and sitting in those seats feels secure and comfortable while sailing, no matter the conditions.
After living on solar power for eight years of cruising and land-yacht travel, we’ve learned that you can never have too much solar power. Groovy’s 555 watts was enough to run all our household appliances as needed, including our nearly 4-cubic-foot DC refrigerator, two laptops, a TV/DVD player, and lights at night. However, it was not quite enough power to run all that plus our stand-alone 2.5-cubic-foot DC freezer during the short days and low sun angles of the winter months without supplemental charging from the engine alternator every few days. For the 10 weeks that we did not have a functioning alternator, our solution was to turn off the freezer, which enabled our batteries to reach full charge every afternoon.
Solar power made a world of difference in our cruise. Not only did it allow us to live comfortably and with ample electricity for weeks on end when our engine alternator went on the blink, but as a “set-it-and-forget-it” system, it also gave us the freedom to anchor out for as long as we wished without worrying about the batteries. In our eyes, the solar-panel arch enhanced the beauty and lines of our boat, giving her a sleek and clean appearance. It was true icing on the cake to discover that the panels and arch system also provided much-needed shade over the cockpit and helm from the hot tropical sunshine. If you are preparing for a cruise, consider turning to the sun for electricity and outfitting your sailboat with solar power.

Solar Panels on Sailboats: An Overview
Before exploring the best solar panels, it is helpful to consider how solar panels on sailboats work and how many you need. Solar panels sit on different parts of a sailboat’s surface and absorb the sun’s rays, converting them into energy. This energy is used to power chargers, fridges, cooking stoves, and other electronics you need for self-sufficient sailing.
Worth noting is that today we will only discuss solar panels and not the batteries, which of course is an essential part of a complete system; we will also not discuss charges or charge controllers.
The products in this post will get you started in the right direction, but if you’re looking for a high-output system, then I suggest you contact someone that can help you calculate your energy requirements.
How Many Solar Panels Do I Need for My Sailboat?
You will need between 2-8 solar panels for your sailboat. The exact amount depends on your sailboat’s space and how many electronics you need to power. Most solar panels can absorb between 100-300 watts per hour. On average, you will need approximately 1500 watts of power each day.
If your solar panels absorb 1500 watts daily, here’s what they can power on your sailboat:
- A laptop charger
- A microwave
- A coffee maker
- An induction cooker
If you want to power more heavy-duty electronics like a washing machine or a television, look for solar panels that absorb 400 watts. For heavy-duty electronics, try installing 5-8 solar panels.
Flexible vs. Rigid Solar Panels
The three main types of solar panels are rigid panels, flexible panels, and semi-flexible panels.
Rigid panels are surrounded by aluminum and made with sturdy tempered glass. They are resilient against various weather conditions but require flat space to install.
Semi-flexible panels can be slightly bent to fit the shape of the installation surface. However, they can’t absorb a lot of power.
One very common type of solar panel used on boats is the flexible panel . Flexible panels are thin and lightweight, and, as their name suggests, they can be added to a wide variety of surfaces.
Here are the pros of flexible panels:
- They are thin and light. Flexible panels are approximately one-eighth the weight and size of rigid and semi-flexible panels. This allows you to add them to various sailboat sizes and surfaces. It also reduces the load on your sailboat.
- They are easy to install. Flexible panels are easy to work with and can be self-installed by following the instructions that come with the panels. Meanwhile, rigid and semi-flexible panels may require expert installations.
- They’re sturdy. Despite being light, flexible panels can bear a lot of pressure – you can easily walk over them.
However, there are also some drawbacks to using flexible solar panels:
- May fly away . As flexible panels are fragile, they can easily be dislodged and fly away, especially in strong winds.
- Vulnerable to scratches . While flexible panels can bear much weight, they may get scratched more easily. Over time this may affect their functionality.
- Not easy to reposition. Flexible panels are generally adhered to the surface of a sailboat using a specially prepared adhesive. Because of this, it is challenging to reposition the solar panels when there is a change of season.
- Less efficient. Flexible solar panels don’t convert energy to electricity or rigid panels. It may be harder to power heavy-duty appliances from a flexible solar panel.
How Many Panels Can I Fit on a Sailboat (Catamaran and Monohull)?
The amount of panels you can fit on your sailboat depends on the size of the panels and the surface space you have available.
You can fit at least two 400W panels on a Monohull and at least four on a Catamaran around 35ft in length. You will be able to fit 4-8 more solar panels if you add a solar panel bracket at the stern.

These are affiliate links, so if you do decide to use any of them, I’ll earn a commission. But in all honesty, these are the exact things that I use and recommend to everyone, even my own family. Sailboats: If you’re looking for the best boat to suit your needs, I would recommend a catamaran. If you’re interested, I can show you the differences between catamarans and other types of sailboats .
Books: For getting started, I really like Cruising catamarans made easy . It is actually a textbook from the American sailing association; it is used to get a cruising catamaran certification. There are some other great books, and I have compiled a list of books about cruising catamarans that you will find useful.
Communication: Being out on adventures, whether it be sailing or climbing mountains, good communications are essential to being safe. I recommend two things Google fi (incredibly simple cellular data all over the world) and Garmin inreach mini (for text and voice in remote areas without cell coverage)
Sailing courses: Online sailing courses are great for beginners starting out their sailing career; it’s an efficient way of learning the basics of navigation, throttle controls, and maritime safety. I suggest starting with two free courses from NauticEd .

Top 3 Best Solar Panels For Sailboats
Last Updated by

June 15, 2022
Choosing whether or not to install solar panels on your sailboat is a big decision. They are not exactly cheap, though they can start to pay themselves off pretty quickly.
This article is going to cover not only why you might want to use solar panels but all the benefits they provide. You will also find a helpful guide on which solar panels would be best for you and your budget. Hopefully, by the end, you will feel confident in your decision to install solar panels on your sailboat and even have an idea of which ones you might like.

Are solar panels on sailboats necessary?
Whether or not you should be installing solar panels on your boat is a matter of choice, not out of necessity. Sailboats get their power from the wind, by harnassing it in their sail. So if you plan to be sailing for the afternoon you probably don’t need solar panels.
You could charge a battery pack from the marina and that will probably see you through several trips. The problems only really start to arise if you are planning to be on your sailboat for longer periods, or even permanently. If you plan to live on your sailboat year-round, even if you spend 80% of it in a marina, you would be better off with some solar panels. Even if it is just as a backup source of power.
Are solar panels on boats safe?
Solar panels are generally pretty safe. They have no moving parts and typically have a very strong protective cover over them so you never come in contact with the electrics themself. So, as a source of power, they are generally pretty safe. The only time they may become unsafe is if they are badly damaged.
Solar panels are often covered by glass plating that keeps them safe. It also helps them absorb sunlight and warmth. This is great, except when the glass breaks. If the glass protective cover on your solar panels should crack and splinter you are at risk of serious injury from sharp shards of glass. Not only is the glass itself dangerous at this point, so are the electronic components inside. They have powerful currents running through them, and if you come in contact with them you may be in for a shock.
Furthermore, if these electronics get wet they can become deadly. Electricity and water do not mix well at all. Being as you are on a sailboat, at sea, the chances of them getting wet is very high. Luckily, the chances of them breaking in the first place are slim to none. The only real way they would break, besides vandalism, is by debris hitting them during a bad storm. There is not often debris at sea, so this shouldn’t be too much of a problem.
What are the benefits of having solar panels on a sailboat?
There are so many great benefits of having solar panels on a sailboat. They can be a lifesaver if you find yourself at sea for a long time. There benefits range from trivial comforts to being the difference between life and death. Here are some of the benefits you might not have considered about having solar panels installed on your sailboat.
Money-saving
Solar panels are not cheap, it is far cheaper to just run a generator or charge your batteries from the marina the whole time. At least, it is in the short term. Over time, it can start to become very expensive. With solar panels, you are looking at a big initial cost (the solar panels themself) and then it’s smooth sailing. You don’t need to pay for power again. Solar panels last for about 40 years before they start to become too inefficient at producing power. The cost of a few solar panels upfront compared to 40 years of marina fees and gasoline for a generator is the financially savvy move.
Emergency power
If you find yourself at sea, the wind dies down (or becomes too strong), and you find yourself stuck bobbing around waiting for more favorable conditions you may run into trouble. Depending on how long you are out there, you may find yourself with dead electronics. Be it a satellite phone, radio, or secondary engine (depending on the boat). Having a set of solar panels and a power bank can be a genuine lifesaver in these situations.
Comfort amenities
Whether you are day sailing or making a week-long voyage, having access to the comforts in life can make the whole journey so much more enjoyable. The amenities may not be available to you without having a constant source of power at sea. Having access to a kettle, tv, videogame system, radio or microwave oven may be the only thing keeping you going at rougher times. As exciting as sailing can be, when you aren’t sailing and are just bobbing around it can be quite dull. The sea is beautiful, but there is only so much time you can spend looking at the water before you miss the comforts of land. With solar panels, you can bring those comforts with you.
Eco-friendly
There are only two alternatives to solar panels. A gasoline generator, and taking power from the grid. Neither of these is good for the environment. Luckily, solar panels are a great third option. Solar panels are completely eco-friendly and are great for the environment. This is not just great for the earth, and your conscience, but for the journey itself. If you are running a gasoline generator at sea you are going to be listening to it thrumming away and smell the burning gasoline. Wouldnt you prefer silence and nothing but the smell of the sea breeze?
How much do solar panels cost?
How much solar panels cost is almost entirely tied into both their voltage/wattage and whether or not they are portable panels. Portable solar panels are great for people who don’t spend a lot of time on their boat or are happy enough living off the marina’s power grid. Permanent solar panels, the kind that may need to professionally installed, can end up costing far more. They are also likely to be far superior and you can pretty much forget about them once they are installed.
Portable solar panels will cost just a few hundred dollars each. You will need a few to be sustainable, but that’s not going to be much of a problem. These portable solar panels can just be rolled out on the deck of your boat, weighed down, and then hooked up to a battery pack. The battery itself here is going to be the most expensive part of the whole set up. A decent-sized battery could set you back a $1000. But, when charged fully it will last days. Even with constant use.
Permanently installed solar panels can cost one or two thousand dollars in some cases. The advantage here though is once they are installed that’s it, you can forget about them. You don’t have to put them up, take them down, and find somewhere to stow them every time they need using. They too will need to be hooked up to a battery, the battery is still only going to cost you $1000. If you are installing permanent solar panels because you plan to be making long voyages, it is ideal to have two or perhaps even three large batteries hooked up to your boat. One to run off, one or two for emergencies.
How do I maintain my solar panels?
Solar panels, unlike gasoline generators, are generally pretty easy to maintain. They have no moving parts and are thus pretty self-sufficient. They don’t need taking apart and they last as long as 40 years. That being said, if they do break they need repairing as soon as possible. The exposed electrics can be deadly when water is thrown into the mix. Which, on a boat, is almost always. The glass cover will need replacing and the electronics inside may need repairing, though not always. Don’t ever attempt to do this yourself unless you are experienced at making these repairs. The cost of hiring someone to do it for you is preferable to being dead. Solar panels have very powerful electric currents, that when in contact with water and yourself can be fatal. As mentioned above, these panels rarely break so you will likely not ever run into this problem. If you do, hire a contractor.
Do my solar panels need cleaning?
Solar panels work by converting the light and heat of the sun into useable power. The process itself is rather complicated but the results are simple to understand. That being said, there are some reasons that your solar panels will stop working as effectively. They all revolve around a lack of sunlight. It could be because it is night time. It could be because it is very cloudy. Or, it could be because they are dirty. If solar panels become too dusty, dirty, and become too covered in grime they stop operating at maximum efficiency. This is not as much of a problem at sea, the sea spray stops dust settling. The biggest thing you will need to clean off your solar panels is salt build-up and slime. This is easy enough to do with some warm soapy water. Freshwater, not seawater. You want to be removing as much salt as possible. Salt is corrosive to electronics, so removing it is important. Never clean your solar panels using pressure washers as they can crack the glass.
Which are the best solar panels for sailing?
There are so many options on the market at various price points. Here are three very different options that will all make good choices, depending on your needs. It is important to consider not just price but power output. Spending a lot of money on solar panels now might not feel ideal, but it is the most cost-effective decision.
1. Renogy Starter Kit
This starter kit is going to be perfect for installing on almost any sized boat. There are four solar panels, each can be fitted permanently to the boat. They can be mounted (and unmounted) easily, for your convenience. They do require a flat surface, but they are small enough that that likely won’t be too much of a problem. This starter kit is very middle of the pack price-wise but should provide enough power for a small to medium-sized vessel easily. It is also possible to buy extra panels individually should you need them.
Wattage: 400/4 (100 per panel)
2. Nature Power Rigid
The nature power rigid is a large, powerful, single solar panel. If you are looking for the right panels to power your entire boat comfortably, these are the ones for you. They are very large so they will need a large flat surface area. alternatively, they can be hung vertically from rails. This is an inefficient way of using them, so you would need to buy more this way. Nature power makes various solar panels so you could find some smaller ones of the same brand to supplement it. This one is not so easy to install, you might need to hire someone to install it for you.
Wattage: 165
3. Nature Power Monocrystalline
Nature power makes a portable solar panel that fits inside a special briefcase. It is perfect for stowing away easily and only taking it out when it is needed. It is decently powerful considering its portable, but there is the inconvenience factor of having to set it up each time. If you planned to buy the nature power rigid, buying one of these portable panels might be ideal for supplementing your power supply when it is especially sunny. Though, it may be cheaper for you to just fit more of the Nature Power Rigids.
Wattage: 120
Hopefully, you now have a good idea about whether solar panels would be right for you and your sailboat. Sailing is great, but the lack of power at sea can be dreadfully boring. Luckily, there are so many great options available on the market. Not just the ones mentioned above. Buying a solar panel is an investment, the initial cost is minor compared to the steady return from all the savings you will make.

The Complete Guide to Solar Panel Mounts for Boats (and Where to Position Them)
How many boaters invest hours researching solar panels? They go all wide-eyed at the shiny panels, marveling at their ingenuity, but how many consider the humble mounts those bright panels sit on?
Let's face facts: Solar panels get all the glory, but spare a thought for the mounts? A good mount can help you get the most out of your solar, increasing your capacity by up to 40 percent.
So maybe it's time for mounts to step out of the shadows of solar panels and into the sunlight (bad pun, I know). Seriously, let's give them some glory.
The type of mounts you have depends on what you want the solar to do and the space available. Is it to charge a cell phone or mobile GPS unit? Or is it to power your entire onboard needs when stationary?
The engine does the hard work when you're moving, so you only really need solar when you're moored up, right? To find out what solar mounts are right for you, we first need to discover what type of boater you are.
Are You a Liveaboard Boater?
Being a liveaboard boater is a different experience to being a leisure boater. You can't just plug-in to a marina or get into an SUV and tow the boat home at the first sign of a rain cloud. The boat is your home.
So power is something you need to manage carefully. And the right solar panel mounts for your boat are essential to optimize the performance of your solar panels.
Are You a Leisure Boater?
As a leisure boater, you'll have different priorities than a liveaboard, and your need to manage power is not so crucial. You'll watch for sunny weather and head out in the boat for a day or weekend excursion . So why do you need solar?
Coolers need power to chill their contents and cell phones need charging. But in the main, the boat engine will power the electrical equipment onboard, because there won't be long periods when you're not moving, unlike a liveaboard boater.
Liveaboard or not, if the sun's power reduces your costs, minimizes the engine's wear and tear and you can afford it, why not?
What Are the Best Boats for Solar Panel Mounts?
Pontoon Boats
It depends on the size and shape of your pontoon boat . Smaller vessels are designed to make the most of the available space, which means seating and guests take priority on the deck .
Newer models, like the Cypress Cay Sea breeze SL 250, have virtually no surface to put solar mounts. Some pontoons have living space.
The Canadian manufacturer South lands builds hybrid pontoon boats, but the average pontoon vessels are for day trips and fishing. Some pontoons have fixed canopies so solar mounts can fit the available flat surfaces .
If you're in the market for a pontoon boat, solar panels and how to mount them are way down on your list of priorities.
Yachts offer a multitude of opportunities to fit solar mounts. Pole mounts are popular with yacht owners, as are fixed and angled mounts . And because most yachts are seafaring, there's little to obstruct the sun's rays way out in the ocean.
In addition, yachts are designed to travel farther, making extended periods onboard inevitable. This means that choosing the right mount is crucial to achieving maximum input.
Canal Boats
A canal boat's design makes them ideal vessels to fit solar mounts. Their robust, steel roofs can withstand the most durable solar panel mounts. This means larger panels can be attached to increase onboard power input.
Because of their long shape, canal boats also allow various panel mount options too. In fact, the only solar panel mount that's unsuitable for a canal boat is the pole mount because of low canal bridge clearances.
Motor Cruisers
Motor cruisers, because of their shape, often have plenty of space for panel mounts to be fitted. With long flat roofs, most motor cruisers (even the mid-range ones) are excellent boats for fixed, angled and even pole mounts .
Featured Boat Care Product
| Exterior Cleaning Kit |
Check Price on Amazon - Better Boat's exterior cleaning kit comes with everything you need to keep your boat clean and shiny from bow to stern. It comes with boat soap, a soap foam spray gun, two microfiber towels, a large sponge and a boat eraser.
The Best Ways to Fix Solar Panel Mounts to Your Boat
Glue adhesives.
There are numerous products available to bond panel mounts to any surface. If you choose this option, it's worth remembering there's some prep work before applying the glue.
Most manufacturers recommend cleaning the surface area before bonding, and some recommend lightly sanding the surface before applying adhesive.
I recommend this Sikaflex-252 White Polyurethane Adhesive The most significant advantage of this glue is that once dried, it can be sanded and painted. Oh, and when choosing adhesives, there's the small matter of no holes .
The fixing solution you choose depends on the boat you have and where it's used. Gluing solar mounts on a seafaring yacht may not be the best idea, especially if you're mid-Atlantic in force nine gales.
You want to know that the mounts are going to do their job and hold your solar panels in place. This Temco Z Bracket Stainless Steel Mount Kit (Available on Amazon) can be easily installed on solar panels. The stainless steel material means it'll never leave rust on your boat.
You're gonna need to bolt the mounts to the roof. Just make sure that when you've drilled the holes, you have enough marine-grade sealant to plug the gaps.
Panel Sizes Versus Types of Mounts for Your Boat
Some solar panel mounts aren't suitable for different-sized panels. The most robust by far is the fixed mount system. If you cruise a lot and don't mind the panels being permanently flat, then these mounts can handle whatever weight you throw at them.
If you want tilt and angled mounts, then you'll need to check with the manufacturer what the maximum load is. The general rule of thumb is: the larger the mount, the bigger the panel it will hold.
Panel weights 100 w or less will fit cheaper mounts. If you want panels over 100 w, check with the bracket manufacturer to see the maximum load weight.
The Best Way to Position Solar Panel Mounts on the Boat
Your first consideration is the obstructions that might hamper the performance of the panels. Get it wrong and all that hard-earned cash you shelled will be for nothing.
Putting a fixed mount for solar on a deck of a motor cruiser isn't any good if you then use a retractable canopy to shield you from the sun and it blocks the panel producing energy. You've just wasted hundreds of dollars.
Another consideration is the mount type, especially if you're stationary for long periods. Tracking the sun by tilting the panels when not moving will increase power input massively.
If you're mostly moving and rarely still, then flat is best. This position optimizes the sun's rays, drawing power in whichever position the boat sits.
Look at your own boat. Does it have large flat areas, preferably high up and unaffected by shadows or obstructions? If the answer is yes, then the next consideration is what type of solar panel mount is best for you.
The Different Types of Solar Panel Mounts for Boats
Fixed Mount
|
|
The HQST Z-Bracket is an excellent example of a fixed mount. It's lightweight and inexpensive. And I mean cheap!
It isn't complicated to fit, although it does require you to drill holes in whatever surface you attach it to. This bracket also enables you to mount the panel to many styles of vessels. The manufacturer even recommends them for RVs.
The other advantage of a fixed mount system is its ability to handle panel sizes from the smallest all the way up to 300w. While these look like a good option, it's worth remembering that if you need the flexibility of moving the panels to chase the sun, fixed mounts won't be for you.
On an ocean-going yacht or a pontoon boat (space permitting) on a lake, the fixed mount system would be worth considering. There'll be minimum obstructions, and while you're always moving, the flat fixed mounts will optimize the charge into the batteries.
There are other types of fixed-mount systems that don't require any drilling.
The Renogy Solar Panel Drill-Free Corner Bracket is a good choice if you don't want to drill holes in your boat roof. They aren't as cheap as the Z-Brackets, but primarily they do the same job.
If you own a boat with a fiberglass body, drilling into the roof simply isn't an option. So how are they fixed? Good old bonding adhesive like Sikaflex 252 (Available on Amazon) .
Adjustable Mounts
The Renogy Adjustable Tilt Mount Bracket mount enables the solar panel to be adjusted to directly face the sun, a feature commonly used when the boat is still.
For the liveaboard boater, the adjustable mount is crucial. By adjusting the angle of the panels, you can increase the input of energy by up to 40 percent.
This particular model can only support a maximum panel of 150w, and the adjustment angle does decrease depending on the size of the panels. So it's worth considering that the max 150w panel, while the most powerful, could give less performance with this bracket, because of the angle that it can be mounted.
What makes this mount different is that the brackets that attach to the roof of your boat are independent of each other, rather than on a long aluminum bracket joining them together.
It means the roof doesn't have to be completely flat. Canal boats would benefit from this type of bracket because they have slightly curved roofs.
|
|
The Link Solar Adjustable Rack Solar Panel Mount is another adjustable bracket, enabling the maximum performance of the panels.
It's a rack system, so it has a long strip bracket that attaches to the roof. The beauty of this system is the capacity it can handle.
If you invest in the 41-inch bracket, it'll take the weight of a 300w solar panel. It may cost more, but given that you'll probably only need two brackets if you're mounting 300w solar panels, it could still be a cost-effective choice.
Just remember where you're going to mount it. Because it's a rack system panel mount, it only fits on perfectly flat surfaces.
|
|
AM Solar 35mm Tilting Mount Okay, I'm a bit sneaky here. Technically, these mounts are for RVs. But if it attaches to RVs, it'll attach to your boat. They're light, compact and give vital adjustability to maximize the sun's power.
This mounting system's advantage is you'll avoid drilling holes in your roof. Each bracket has a VHB tape strip, which bonds to most surfaces. Fiberglass gives the best bond, but if it works for RVs, then metal surfaces will work too.
A word of caution: These brackets attach by drilling into the solar panel's side. This is the crucial bit: If you're piercing the side of your panel, there's a strong chance you'll invalidate the warranty.
It's worth checking before you do. AM Solar sells compatible panels with pre-drilled holes, which massively cuts down on your choices and ability to shop around for the best price.
Pole Mounts
Missouri Pole Mount
Let's start with a positive: This pole mount is 100% American. That's got to be a good thing, right?
Pole mounts are excellent for panels that can be raised up to avoid obstructions. They're also good for boats with limited solar panel mounting space.
Pole mounts are popular with yacht owners due to their maneuverability and height adjustment properties. This particular pole system can handle two 100w panels, so there's no need to compromise on the energy you create.
What We've Learned
All the solar panel mounts featured are value for money. What to consider is the panel size. Is it better to have two 300w panels, reducing the number of solar mounts? Or do you go for six 100w panels, increasing the mount's overall cost? That'll depend on your boat's available space.
By far, the easiest to use is the fixed flat system . Glue or bolt the brackets on and away you go. No fuss. But again, mounting space may be an issue, so this type of mount won't be for everyone.
The most efficient is the angled, adjustable mount . Liveaboards should consider this when buying solar. Increasing your panel's performance with the ability to angle towards the sun is vital if you're stationary for extended periods.
In winter, when the sun sits lower in the sky, you'll reap the benefits of angled mounting systems for sure.
To clean your solar panels, simply rinse with a boat hose and nozzle and swipe with a silicone squeegee . This is a quick task to do when you've got out the boat soap or hull cleaner for the rest of the vessel.

Mounting a solar panel on the stern pulpit rail
- Thread starter Tom Okey
- Start date Apr 24, 2023
- Catalina Owner Forums
- Catalina 30
Hey'all, I'm aiming to mount my new Renogy 100 w solar panel on my starboard side stern pulpit rail with some SeaDog round rail clamps that I can mount securely on the outer frame of the solar panel. The problem is that my '83 Catalina 30 is currently a 6 hour drive from me and from the drill and other tools I have where I'm at, and Google searches haven't revealed the length of the straight part of that upper rail forward of the bend at the back corner of the pulpit. The solar panel is fully 106 cm (42") long, which I think might be slightly longer than this straight section of rail. Does anyone know the length of the straight part of that rail? If shorter than 106 cm, I could potentially mount a bracket across the panel for an additional place to mount the round rail clamps. Are there any other suggestions? Bonus question: Do you have any suggestions on the best kind of gland to get the two 10AWG wires through the deck, or any other ideas for that? In case you're wondering, I also bought a 3' telescoping pole extension, which I plan to mount to the other side of the panel underneath to adjust the angle of the solar panel. Thank you very much!
Tom, I don't have measurements, sorry. However, I think I'd take a different approach. The clamps will work, of course, but I would build a frame to mount the panel that would allow you to place the clamps at whatever width you prefer. A simple frame will also allow you to include additional supports for angle support, using the vertical stanchions. I envision a flat metal bar running the length of the panel with cross pieces at each end and perhaps a couple intermediates. The clamps can be fixed to any point on the longitudinal piece, the support brackets on one or two intermediates. There's also the additional benefit that you'll be able to relocate the panel if desired. Good luckl.

Joe said: Tom, I don't have measurements, sorry. However, I think I'd take a different approach. The clamps will work, of course, but I would build a frame to mount the panel that would allow you to place the clamps at whatever width you prefer. A simple frame will also allow you to include additional supports for angle support, using the vertical stanchions. I envision a flat metal bar running the length of the panel with cross pieces at each end and perhaps a couple intermediates. The clamps can be fixed to any point on the longitudinal piece, the support brackets on one or two intermediates. There's also the additional benefit that you'll be able to relocate the panel if desired. Good luckl. Click to expand
dmax said: I no longer have my C-30 but I don't think the length of the top pushpit tube from the stern forward is 42" - on my current boat it is 18", I don't think the C-30 could be that much longer if at all. Here's the best picture I have showing my C-30: View attachment 215005 I mounted a 50 watt panel on the pushpit at the stern, I don't have room for a 100 watt panel there. I attached aluminum bar stock to the bottom of the panel so I could attach the mounts where I wanted them. You could use aluminum angle "iron" for more strength. Here's the cable gland I used, plenty of room for two 10 awg wires: STANDARD VERTICAL CABLE ENTRY The Seaview Cable Seals / Cable Clams provide waterproof cable routing.

Tom Okey said: Thank you for that Joe! I think you may be right....I wonder if a couple of intermediate cross bars would do it (if they were in the right spot and wide enough to help mount the clamps). In any case, you got me thinking, and I am now planning to design something along these lines. -Tom Click to expand

Mounting solar panels on a sailboat was not difficult, but a few key decisions made a huge difference in how effective our panels were. A solar-power installation on a sailboat is made up of two independent systems: one system to charge the batteries, and another system to provide 120-volt AC power for household appliances.

Solar panels have become game changers when it comes to supplying power while off the grid. Marine solar panels can charge anything from batteries to computers to bigger electronic appliances. What are the best solar panels for sailboats?
Are solar panels on sailboats necessary? Whether or not you should be installing solar panels on your boat is a matter of choice, not out of necessity. Sailboats get their power from the wind, by harnassing it in their sail. So if you plan to be sailing for the afternoon you probably don't need solar panels.
The Canadian manufacturer South lands builds hybrid pontoon boats, but the average pontoon vessels are for day trips and fishing. Some pontoons have fixed canopies so solar mounts can fit the available flat surfaces. If you're in the market for a pontoon boat, solar panels and how to mount them are way down on your list of priorities.
Sailboat solar panels offer a convenient way to harness the energy from the sun to power your boat. Learn how to install them!
Researching solar panels for the first time in 13 years, we discovered that much had changed. Panels produced higher output for their size, but larger panels were being manufactured to meet the ever-growing demands of boaters. Our usage had actually decreased over time as our three children grew up and moved off the boat, and the space allotted ...

Hey'all, I'm aiming to mount my new Renogy 100 w solar panel on my starboard side stern pulpit rail with some SeaDog round rail clamps that I can mount securely on the outer frame of the solar panel. The problem is that my '83 Catalina 30 is currently a 6 hour drive from me and from the drill...
Solar Mounting Hardware Every solar panel needs to be mechanically mounted and installation on a boat becomes that much more challenging due to the nature of structures available as well as the harsh salt water environment.
