Excellent panel. The assembly is on top, even the body is on top. Even better, I bought it on a lightning deal and got a $25 off, even though I had to spend $12 of that $25 to buy an Anderson SAE adapter to connect to my controller. Works great, I got 4 amps out. on a day with just a misty sun. I have a maximum of 5.1 amps. Very nice folder.
