I am not sure where to start this one. Seems we had nothing but issues with rack system that we mounted the solar panels on. No matter what we did, the screws kept breaking. We spent an afternoon replacing them in a Home Depot parking lot, only to have the break after a test drive down the road. The road was not rough at all.
So we made the decision to take the whole thing down and we ended up with 600 watts of panels in the bed of the truck for now. I have no idea if that is going to be enough when we stop but for now, it seems to be working. Only future usage will tell us anything.
