The DuraVolt panel also comes included with battery and lighter plug adapters, further improving its versatility. Of course, the main advantage of this panel is that you can place it nearly anywhere on your boat.

Unlike other panels, which may require a large, open area so that they can be installed, you can place this model on all but the smallest of boats, jet skis, fishing kayaks, sailboats, etc. without any trouble.

How do you install a marine solar panel if you can’t find a suitable flat surface on your boat? This 100-watt panel from Renogy is the solution!

Its innovative, flexible design makes installation a lot less of a hassle for you. This solar panel is also lighter and thinner than the competition, though it features a comparable power output. It’s ideal for use on a sailboat.

This panel is designed to flex up to 248 degrees without any damage or cracking. The junction box on this solar panel features fully waterproof IP68 construction, so this model is ideally suited for marine applications. During the off-season, the light weight of this panel also makes it easier to dismount it from your boat.

The main downside to this panel is that it’s more expensive than comparable 100W models, and that’s due to the advanced materials which allow it to bend so far. If you’re looking for a flexible solar panel that won’t crack or break at extreme angles, we’d highly recommend this one from Renogy.

Marine Solar Panels Buyer’s Guide

Best Marine Solar Panels

Who Should Buy a Marine Solar Panel

Boaters, sailors, and anglers tend to be the most frequent customers of marine solar panels, and that is relatively unsurprising since many of them own their boats. A marine solar panel can be used for a wide range of applications, but the most frequent one is battery maintenance and battery charging.

To ensure that a boat’s battery doesn’t die, it will have to be periodically recharged, and this has historically been accomplished through the use of a diesel motor. Solar panels are a more efficient and ecologically-friendly way to restore your boat’s battery, as you’re harnessing the power of the sun instead of burning fossil fuels.

Important Features to Consider

Power Output

The first thing to account for when you’re buying your new solar panel is the amount of power that it’s capable of generating. The ideal level of power output will depend on what you intend to use the solar panel for, and it can range from as low as 10W to 400W and beyond on larger vessels.

Ease of Installation

Another crucial thing to make sure of before you purchase your solar panel is that it’s easy to install, especially if you’re a first-time user. Pay close attention to the size of the solar panel and whether or not it comes with mounting holes drilled into the frame. Keep in mind that some solar panels may not come included with mounting brackets.

Frequently Asked Questions

Will water damage my solar panel?

Marine solar panels are designed to be water-resistant, and most will feature an IP rating to give you an idea of exactly how resistant they are to the elements.

Where should I mount my marine solar panel?

You’ll typically want to install your solar panel in an open, unshaded area of your boat where it will be sure to get as much sunlight as possible. This will ensure that your solar panel is reaching its peak level of power generation.


Other Products We Looked At:

Newpowa 200W Monocrystalline 200 Watt 12V Solar Panel

Newpowa 200W Monocrystalline 200 Watt 12V Solar Panel
These marine solar panels from Newpowa are one of the more powerful options that we’ve reviewed, with a rated output of 200W. Despite the power that they generate, these are some of the more affordable solar panels that we’ve come across, with a similar price point to some popular 150W models.

Installation is relatively simple, as the diodes have already been installed in the box, and the MC4 cable comes pre-attached. Reliability also won’t be a problem, as this solar panel comes included with a 25-year warranty for its power output. The use of anodized aluminum for the frames makes these panels resistant to damage and corrosion.

However, we weren’t as impressed with this solar panel as we were with some of the earlier models, mainly due to its efficiency when it came to power generation. While this model is rated at 200W, we often struggled to reach that level of power output.

Key Points at a Glance

  • Resistant to wind and snow
  • Uses low-iron tempered glass
  • Anodized aluminum frame

Renogy 100 Watt 12 Volt Eclipse Monocrystalline Solar Panel
This next solar panel from Renogy features a sleek design that makes it our best-looking choice. If you’re looking for an elegant set of solar panels that will complement the look of your boat, then this model will be the perfect choice. These panels have been redesigned with a thin black frame and invisible grid lines on the cells themselves.

Like with other Renogy marine solar panels, this product features a waterproof, IP65-rated junction box. This model also features a positive output tolerance of between 0% and 3%. Since the panel is compatible with all of Renogy’s mounting systems, there are many different ways to mount it to your boat.

Despite this model’s good looks, it didn’t get into the top five products because it’s a little more expensive than other 100W solar panels, somewhat diminishing its value for money. However, if you’re willing to pay a little bit extra to make sure that your solar panels look sleek and futuristic, consider this product.

Key Points at a Glance

  • Super-sleek design
  • Pre-drilled holes
  • Waterproof junction box

This 200W solar panel set from SUNGOLDPOWER is one of the most powerful products that you’ll find in its price range. If you want to save some money on your marine solar panel, but you still require high output, we’d highly recommend this solar panel kit. Along with two 100W panels, this set comes with everything that you need to get started.

When you open the box, you’ll find a wide range of accessories that come included, such as a pair of MC4 cables, z brackets for mounting, and MC4 Y-branch connectors. Installation is simplified by the inclusion of pre-drilled holes on the panels’ rear ends, though their large dimensions may make them a little harder to mount alone.

Unfortunately, this product didn’t make it into the top five because its build quality felt a little cheaper than some of our top picks. Of course, this is to be expected when you consider how much you get for the relatively low price. Keep in mind that this is still an excellent high-output panel set if you’re on a budget.

Key Points at a Glance

  • Comes with extension cables, Y-splitter, and more
  • Features a 20A PWM charge controller
  • Consists of 2x100W panels

Renogy 200 Watts 12 Volts Monocrystalline Panel Solar RV Kit

Renogy 200 Watts 12 Volts Monocrystalline Panel Solar RV Kit
This product from Renogy is relatively similar to the solar panel set that we just reviewed, but it features a slightly higher price point and a few key differences. Along with the adaptor kit, tray cable, and other accessories, this solar panel also comes included with a Bluetooth module for wireless control.

Due to the higher price of this solar panel kit, it features excellent construction, and you can feel that it’s built to last. This product is also designed to put up with strong winds and heavy snowfall, so you won’t have to worry about it getting damaged by the elements, even during the off-season.

While we were very impressed with this product, the high price point held it back from a spot in our top five best solar panel selections, as it simply doesn’t offer as much value for money as some of the competitors. On the other hand, if you have a larger budget and you don’t mind spending the money, this is a very well-built product.

Key Points at a Glance

  • Features 21% solar cell efficiency
  • Comes with a 30 Amp PWM charge controller

Key Points at a Glance

  • Comes with Z-brackets, mc4 adaptor kit, and tray cables
  • Features the Renogy Wanderer charge controller
