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

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.

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


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.


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.


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.
