Solar panel overkill?
I have been mentally designing a solar system for our small class C. I have 2 6 volt GC batteries and have no extra room to add more. I was originally thinking of installing a 24V 235 watt panel fro...

I would not recommend a 200+ watt solar panel for any RV. Unless you have a really large area that is not over a curved roof that will make it to high in the wind while driving.
The problem with 200 watt panels is there is to many square feet of panel, and typically only 4 mounts. You can have a lot of uplift during certain driving conditions. Or the pane can act like a wing, and take off, ripping it's mounts from the top of the RV.
My larger pair of panels are 120 watts and the pair cover the front 4' of my motorhome. They whistle while driving, probably catch a lot of air, but have not managed to pull their mounts loose in 10 years of use and about 25,000 miles driving.
The panels measure 65.55" X 39.57". Was thinking of making them tilt not so much for the angle of the sun but for roof access so I could tilt them out of the way. I could make 6 mounts instead of 4 if that is advisable. Would just be one more knob to unscrew for tilting. Not sure yet how much roof is arched - will have to get up there again and check. Do you think that molly bolts or toggle bolts would rip out of the roof from wind?
