Best Boat Solar Panels reviewed

Your boat should be your home away from home, in every way possible. For many, their idea of a home involves some sort of access to electricity and the appliances that come with it. 

That’s why boat solar panels are all the rage at the moment. The ability to power your electronics while on board is taking boating excursions to the next level. Listening to music, catching the live football game and even being able to use solar power for your fridge to keep your food & drinks ice cold is a worthwhile addition to your day on the water.  

We took the time to round up six of the best boat solar panels on the market today. We’ve reviewed the pros and cons of each in order to give you a comprehensive analysis of what to expect from each of these products. 

Before we get into each one, let’s break down the world of boat solar panels as it currently stands. 

About Solar Panels

Boat solar panels have gained popularity in recent years since boat owners discovered that they could bring the comforts of the shore on board.  

Like regular solar panels, boat panels use the energy from the sun to deliver power to a central outlet point where appliances can use it.  

Basically, solar panels absorb the light and energy rays from the sun & are able to store this power for long periods of time. This is great for boating excursions that continue from day into the night; lights on and around the boat can be powered via the panels for the duration of the trip.  

Boat solar panels require some basic installation before boat owners can successfully make use of them. They need to be securely fitted to the boat and out of the way of any obstructions that might hinder the energy flow. 

Solar Charging

Solar charging comes with many welcome benefits especially when being used on a boat. 

Keeping the batteries of all of your electronics and/or appliances charged is a big one. Having a charged cell phone handy at all times, for example, is a very important part of boating safety.  

A boating trip is only as successful as the navigation equipment that it makes use of. Navigation equipment requires energy to run! A solar panel is the surest way to ensure you’re never left without direction. 

A Few Things to Keep in Mind

Solar panels are measured in either watts or amps. The number of watts or amps on your device will determine how much power the unit is able to emit at any given point and also how long the panel will be able to deliver power for.

Higher powered units can be used to power more devices at one time than lower rated units. 

For optimum power, your solar panel will need to be fitted as perpendicular to the sun as possible. Take time identifying the perfect spot on your boat from which to mount it. 


Specs are just as important to find your ideal fit based on preferences and needs.


Consider whether you’d like to mount your panel to your boat permanently or temporarily. Solar panels come in handy in non-boat related situations as well, so if you’re into camping then you might consider using a removable unit so you can take it elsewhere.


A charge controller is necessary if you’ll be using your panel to charge multiple batteries at a time. This device prevents batteries from overcharging and will save you money in the long run from having to replace burnt out battery packs. 


The amount of energy you need to generate for your boat will depend solely on its size and the number of devices that need to be powered. 


Boating solar panels come in various main types:

  • Mono-crystalline
  • Multi-crystalline
  • Amorphous thin film silicon

You can identify mono and multi-crystalline cells by their dark black tone. The amorphous thin film is characterized by its blue or grey shades and is the most common type of cell used in affordable solar panels.


For a boating solar panel, there’s usually no need to fork out more than $500 on a quality unit. In the event of your boat needing slightly more power than most, then a few hundred dollars more may be necessary.
