Solar Panels for Sailboats Buyer’s Guide

Solar panels are a great way to make your vessel a little more self-sufficient and cost friendly. As long as there is sun in the sky, these solar panels can be used for anything from charging batteries, to working your stereo or even supplying your entire vessel with renewable energy.

Take a look at our buyer’s guide for some tips and features to keep an eye out for when making your purchase.

Amp draw

This refers to how many items you plan to power with your solar energy. Create a checklist of the items you wish to power and much energy is required. From there, simply calculate the amp draw and buy a set of panels that is capable of handling the task.

Actual out vs. maximum output

Remember, maximum output refers to the amount of energy that can be produced and stored on a perfect, sunny day. If you live in a region that isn’t always sunny, you won’t be getting that maximum output.

Size

The size of the panels you choose will need to coincide with the length of your vessel. Typically, the more energy your boat consumes, the bigger the panels required. If your vessel is on the small size, try to purchase solar panels that are small yet efficient, generating the most power yet taking up little space.

Mono-crystalline vs. polycrystalline

Mono solar panels offer high efficiency and power output but tend to be on the expensive side. If you’re on a budget, consider using polycrystalline panels, which produce slightly less power but are much more affordable.

Thin film silicone panels

These are a great option if you have limited space. Cheap and highly flexible, these panels can be mounted onto curved surfaces; however, they are not as efficient as their crystalline counterparts and tend to have a shorter lifespan.
