I love this product. I had been having problems with my shore power at the marina my boat is kept. It kept frying my battery chargers. I decided to shop around looking for good deals on solar panels. I found this panel and decided with the warranty (5 year limited warranty on workmanship and material, 20-year 80% power output warranty) it was the best deal for this size. The customer service was great. I took it out of the package as soon as it arrived and laid it down in the sun in my back yard. I got 21 volts and 1.4 amps which equals 29.4 watts. It is in a sturdy aluminum frame, not plastic, and looks great. I plan on buying more solar panels from CD Technologies, probably larger than this one. They have sizes from 1 to 175 watts. I would recommend this product to anyone looking to power a solar project.
