Any experience with 'Earth 4 Energy'?

Does anybody have any experience with Earth4Energy.com? The claim is that you can build your own solar panels for $200 or less, wind generator for $100 and for $50 they tell you how. Sounds too good, but who knows...

Never heard of them but a quick google brings up a fair bit of home made solar and wind

homemade solar panels - Google Search

Making a solar panel, and making one that can withstand the marine environment, are two different things. I cannot imagine a homemade solar panel holding up for that long.

Ditto with wind, but maybe a bit less so. Wind could be assembled using discrete components, but each one would need to be corrosion resistant. Not that easy.

I don't see any reason why building a solar panel or wind generator for a boat is any more complicated than building one for the desert. In either case, the unit must be made for the environment. Marinizing products is often little more that a spray on sealer.
The main advantage to building your own solar panels is that you can design them to fit your boat.
