[RE-wrenches] Need info resource re wind & hail damage

[Larry Crutcher, Starlight Solar Power Systems]

William, sounds like you have been hiding in my showroom. We see this weekly and it is definitely not good to get in the middle. Just offer the facts, plainly presented.

Alan, If anecdotal stories will help, I personally had my PV system survive a 12 minute hail storm with up to 2.5 inch sizes. My modules were facing the the hail direction. The PV survived unscathed but the house had $23,000 in damage. We also have had RV customers tell of windshield smashing stones with no harm to the PV modules.

Good luck!

Allan:

I have some resources for you right here:  don't get involved in marital disputes.  Consider this:

They, collectively, either want PV or they don't.  Until they agree they want solar, you are wasting your time siding with one against the other.  All of the evidence in the world will not change a mind that is not willing to change.

Good luck.

My husband says it turned him off solar.It comes up every time I talk to him. Either he is complaining about the wind or the hail or whatever.

Anything that came from Sandia Labs would be ideal, but it just has to be reputable enough to satisfy a grouchy retired national lab engineer. Web links, reports, product warranties, etc. - all good.
