Recommended height for solar panels
I am laying out a roof plan, looking at shading. I made a good scale drawing and now need to assume a mounting height in order to finalize the shaded no go areas. I suppose there are different opinion...

Hi,
While it is good to have 1" of space between the roof and the panel will allow air to circulate below the panel. Panels make more power when cooler.
3" of space will allow to much air below the panel, and can cause problems with the air blowing the panel upwards while driving. You certainly never want the panel higher in the front, and higher in the back can cause excess pressure on the rearward roof mounts. It is not an exact science, just keep it level with the roof. ANd I would never consider mounting on a angled section of a roof like fifth wheels used to have between the lower section and the upper section. Nowdays fifth wheels typically have higher roofs in the living area and do not have that sharply angled roof area.
