When it comes to getting the right solar panel for your boat, there’ll be a few things that you’ll be looking for.

The first thing is size. You want something that will fit on your boat and not take up too much space. The second thing is weight.

If you’re going to be using this on your boat then you don’t want anything too heavy.

And finally, you want something that’s easy to install if you are going to DIY but a professional solar installer shouldn’t have a problem either way.

But if you get a marine solar panel, then you can be sure that you’ll have everything you need to be completely self-reliant when you are out on the waves.

This is very important if you are fishing in deep waters and far away from any sources of power.

Here’s our guide to the best marine solar panels.

Buyer’s Guide

When it comes to buying the right marine solar panel for your boat, there’ll be a few features that will be essential.

The weight will factor into it, as you’ll want to have something that you can shuttle aboard your boat without too much strain. You also don’t want a solar panel that will capsize the boat. Here are a few other things you should be looking for:

Size

You’ll need to decide how big of a space you’re willing to devote to installing your solar panel.

It’s best to buy a solar panel that will fit snugly into your boat so that you won’t have to move it around every time you head out onto the water.

Power Output

Your solar panel needs to be powerful enough to provide all of the power that you require.

For example, if you plan on charging multiple devices, then you’ll want a solar panel that has enough power to keep them charged.

On the flip side, if you only plan on powering one device, then you’ll want something that is smaller and lighter.

Portability

If you’re planning on taking your solar panel along on trips, then you’ll want to look for something that is lightweight.

If you’re going to be carrying it around for long periods of time, then you’ll want it to be durable.

Durability

If you’re going to be using your solar panel in harsh environments, then you’ll want some sort of protection system.

A good solar panel will come with a built-in protective cover that will protect against dust, dirt, and moisture.

Warranty

The warranty is another thing to consider when purchasing a solar panel. Most manufacturers offer a 3 year or 5-year warranty, depending on what type of product they sell.

Warranties vary by manufacturer, but most will include replacement parts and labor.
