    I certainly would never accept any workers walking on any panels I owned.

    This is one of those situations where any stress problems may not show up for 5 yrs or more .Then faults may appear in the panels . Then what.? You are going to have a fun time getting the contractor to accept the damage (mabe not even in business)and the panel manufacturer may reject the claim for faulty panel..

    Better safe and not do it. than accept it and regret it later.

      That is 40 pounds per sq FOOT not inch uniformly distributed load. 100 lb woman in spike heels can create a point load of over 400 PSI. I have seen many floors dented and ruined by spike heels.

          Yep My Bad in a typo of PSI istead of PSF.

          Point still stands as Floor live loads and roof snow loads are calculated the same way.

              I looked at your home page and suddenly your comments make more sense.

              Any way enough

              Do you think you could drive a car onto solar panels?
              Please I know these are test conditions but this is a very cool video

              Hey and there is even a lady with some high heels for ya
              Those are one tough panels. Looks like a quality product and something I would very much like on my house.

              It is a shame their stock value has gone down from about $66 per share at their peak in 2007 to $0.51 as share today.
