  14. Panel (Array) ventilation

    I found this on the internet - ( Roof mounting clearance Solar panels you want to mount on a roof must have at least 3 inches but 4 to 6 inches is better, distance between the roof and solar panels frame. The reason for this clearance is that it allows air flow under the solar panels for cooling them. You must never mount panels in a way there isn't any air flow under them because they can become very hot in that way. )

    Thanks 4 all the info - correct me if im wrong : i have 12 x255w already mounted flat on roof and ordered 9x320w (should get them in a week ) from all this info I feel it's better to put (aluminum ) rails and brackets for the new panels - will pay itself off over time ( Not worth it to remove and reinstall the old one's on rails ) Dose anyone know what is the minimum distance it should be between the roof -panel ?
