Best Solar Panels For Marine Use

The best solar panels for marine use need to be suitable for a saltwater environment, and marine type vessels.

Most commonly, people seek to use solar panels for charging marine batteries –  boat and yacht battery set ups (or any other vehicle with DC batteries).

These panels not only need to have the sufficient watts and voltage requirements, but features like water resistance and corrosion resistance are important too.

There are rigid (stiff) and flexible panel options which offer different benefits and drawbacks.

A big benefit for marine vessels with motors, like boats, is that solar is cleaner, and also cheaper in the long term than say diesel fuel.

Let’s have a look at some of the available solar options…

Best Solar Panels For Marine Use: Buyer’s Guide & FAQ

What Are Solar Panels For Marine Use

Marine means on the ocean – this can mean boats of different types, yachts, kayaks, and any mode of sea transport or use.

So solar panels for marine use are solar panels you can use on these sea faring modes of transport.


What Types of Solar Panels Are There For Marine Use

The main types are:

Rigid/Hard Solar Panels

Flexible and Bendable Solar Panels


A small form of solar panel for marine use would be the small 6-20 watt folding solar panels (Goal Zero does quality small 20 Watt panels)), or even the waterproof solar panels from Voltaic Systems.


What Are Solar Panels Used For In A Marine Environment

There would be two main uses:

1. Rigid and and flexible panels can be used to charge DC batteries that power boat lights, electronics, pumps etc.

2. Small solar panels can be used to charge USB devices, and small handheld devices like smartphones, tablets, radios etc.


Which Solar Panels To Get For Marine Use – How To Choose

It really depends on what you want to charge.

Read this guide on calculating your solar panel size and number for some tips.

But, when choosing the solar panel to get, consider the following:

1. Do you want a rigid, flexible or folding solar panel?

2. What size (in watts) solar panel do you want?

3. Are those solar panels rated for the voltage of batteries you want to charge?

4. Do you want to use the solar panel for any other application like camping, Rv’ing etc.? If so, check what the panels are designed for

If we had a regular boat set up of say 1 or 2 12v batteries, we would probably stick to a rigid solar panel setup – as they are most cost effective and efficient (as long as you are OK with a more permanent installation).

You also get more established companies with the rigid solar panels.
