Solar Powered Boats have become the norm among serious cruisers. Turn your boat into a solar yacht with the addition of a solar system.
If you're looking for self sufficiency on the water a solar powered boat just may be the answer

Power your boat without the negative environmental impact of running an engine at anchor. Solar yachts have all the power needed to live comfortably aboard for a week, a month or years, all provided by a few solar panels.
No more starting the engine and polluting pristine anchorages with carbon emissions and noise. A solar powered boat silently soaks up the sun and converts it to clean energy that powers all of your necessities. Some of the benefits of a solar powered boat are:
The number and size of solar panels required depends on how much electricity an individual boat uses. Throw in variables like geographic location, time of year and electronics on board and the issue can become very fuzzy. Here's what we have on our boat, "Pacific Jade", which is pictured above.
The closer you are located to the equator the more of the sun's rays strike the panels. This obviously translates into more power production per panel. The panels work most efficiently when the sun is high overhead (from 1000 hrs to 1500 hrs. (10am to 3pm)
We lined the inside of our fridge with that silver bubble stuff used for blocking the sun inside windshields.
They're easy to cut to fit and stay in place once established; easy to clean too.

To the right is a photo of one of our buddy boats "Grey Max". Her solar array consists of 8 pv panels and in the center is a solar water heater.
Grey Max is so self sufficient that her owners don't even plug in when they're at the dock.
Note that the panels are mounted over the cockpit to shade the occupants and to allow the panels to freely access the sun with few obstructions.
