Scary Photo of the Month – May

I appreciate Shoal’s new arc fault technology as shown in this advertisement, however I was shocked to see the photo of a man standing on PV modules.

This is a reminder that you can not stand on solar PV modules like this if you expect them to last 25 years. Standing on the modules creates micro fractures on the cells that will lead to premature failure. If you were ever in a difficult situation where you needed to step on a module, at least be sure all your weight it applied to the frame and not on the module surface (but even that is risky).
