How to Choose the Best Marine Solar Panels

Solar panel


All solar panels should serve for a long time. Don't buy a solar with one year of service time and consider it as an accomplishment. In fact, the lifespan of a solar should be in decades, but for a start, choose a solar that will last for at least five years.  

Waterproofing qualities

Marine solar should be designed to live with its mode of transportation- water. To avoid water incapacitating the solar, go for a solar with waterproofing properties. It will compliment your offshore life.


Flexible solar is easy to use. You can easily mount it on an array of roofs; hence, it's a better option to use on marine vessels. Also, flexible solar is fancy and aesthetically appealing.


Since you are living an off-grid mobile life, there is no need to purchase solar panels that are difficult to carry. They will render your mobile life, immobile! A portable solar panel is best suited for you.

Best Marine Solar panel FAQs

Which is the best marine solar?

All of the above highlighted solar panels are the best. The above is an expert-generated list on the basis of reliability and efficiency, but the choice depends on your needs.

How much power should a solar panel produce in order to run a fridge on a boat?

Over 250 Watts!  Domestic refrigerators consume at least 250Watts. Though solar-powered fridges consume less solar energy, there is no significant difference in the power consumed. To be on the safe side, get a 300W solar.

How often should I wash my marine solar panel?

Two times a year. Cleaning solar panels is a rule of thumb because they gradually accumulate dirt. Dirt reduces the amount of light reaching the cells, and on the receiving end is a severely crippled power supply system.
