WHY USE SOLAR PANELS ON YOUR NARROWBOAT?

Tilting solar panels for boats Energy independence - solar energy gives you a level of reliability and independance.
Convenience - when you know you are going to be home too late to run the engine you won't have to worry about your batteries, or turn your fridge off. Many customers report back that the greatest benefit for them has been freedom from being tied to the boat. They are able to go out for the day and are not constantly worrying about hurrying back to do a two hour engine run - I'm sure we can all relate to that!
Financial benefits - solar energy is free and there is enough for everyone. Less running of your engine means less spent on fuel. The intervals between engine services will be longer if you run your engine less. Your batteries won't sulphate as quickly when kept topped up by solar panels, so will last longer. Your panels will pay for themselves in the money you save.
Environmental impact - unlike fossil fuels, solar energy doesn't produce harmful pollutants.

The latest solar PV technology enables you to use energy from the sun even on a cloudy day. How long will the solar cells last? Right now, solar power systems are projected to last for about 20-25 years.

So, how the heck is electricity made from light? Scientists discovered that some materials give off electrons when exposed to light. Other materials absorb electrons when light shines on them. By fusing these materials together, an electric pump is formed that causes current to flow, providing electricity. Solar cells are made up of these materials.
