Re: Photovoltaic panel weights

[Subject Prev][Subject Next][Thread Prev][Thread Next]

     The dead weight of non-ballasted panels is usually a non-issue (3-4 
PSF). The larger problem is usually in how the support systems deliver the 
snow load on the panels to the roof structure below at discrete points vice 
 a simple area load.
