This solar array has three, 15-watt panels mounted on aluminum rails for a total of 45 watts and it measures about 3 feet square. I removed it from my boat recently and have the original docs and the controller, which appears to have problems. I think it came originally from Harbor Freight; I don't know the age.
The price is right! Pick up on Kent Island.
I can't figure out how to include the photo in this posting, but can send it to you by email.
