Solar questions
I'm mounting three 210 watt Newpowa panels on my 30'Class A motorhome. I'm using Renogy Z brackets to mount them to my fiberglass roof. The panels are pre drilled to accept 8 of these brackets. Do you...

4 are plenty for the panels, but for the fiberglass roof I would use at least 6.
I second on cutting your own angle iron aluminum brackets if this is possible for you. I did this and then just use self-tapping screws into the sides of the panels where it is safe to do so through the frame and not hit any critical parts.
Are you using VHB tape to the roof or mounting with hardware through the roof? Fiberglass roof can be a solid roof or can be rolled-out sheets that are more flimsy, so just curious.
You can use wire that is thinner than the electrical optimum gauge of course and it will work just fine. The differences will be only noticed when you need maximum charge and every last solar particle you can catch..
I would just get a higher amp controller so you can run in series and use the thinner wire. Is this an option? Did you keep the receipt for the controller? In the long-run you will be glad you did.
