Hi Bill -
I'm adding this question to the wrenches list since it is technical in nature. I don't know about standard modules, but I've heard that it is not good to leave SunPower modules sitting out in the sun without connecting them for long periods of time. One of our installers who worked on a large SunPower commercial installation said that they were instructed to ground the positive lead of each module to a ground electrode until commissioning the system. I have contacted SunPower about this issue and I'm still waiting to hear an official response.

Any experience with this? Anything to it? -- Best, Bill Roush Heartland Solar Energy Industries Association www.hseia.org
