This is a fantastic small panel. For anyone who wants a great panel to experiment with or for educational purposes this would be fantastic. It feels well built and pretty solid.

I did notice that the wire going into the junction box on the back of the panel seemed to be a bit loose as if it wasn't solidly connected to the box. This may be normal (I'm not sure as this is my first panel) but it did NOT have any impact on power output when I moved the wires around, so the electrical connection was solid. I put a little low temp hot glue on it to keep it from moving too much and haven't thought about it since. I know that other people with this panel have not had this problem so I probably got a fluke.

The panel works great though, despite this. I have measured 20v (open circuit) in bright sunshine while INSIDE with it. I have it connected to a Morningstar PWM charge controller and a 7.2Ah SLA batt and it had no problem charging it or keeping it charged.

Overall this is a great panel, I would buy it over again even with the seemingly strange wire.
