Hi Allen
For what it is worth I had a house in Puerto Rico with two modules on the
roof. Hurricane Marilyn blew the roof off of the house but the panels
stayed on for the ride. The roof landed upside down pinning the modules
under the debris. These the UniSolar UPM880 (non glass) and they survived
Alan,
My personal array survived a tennis ball sized hail event unscathed.The hail
came in out of the west on a 50 MPH or so straight line wind. My array was
fixed rack at 37 degree tilt. The hail hit the modules at enough of an angle
that they all survived. (7KW of 120 watt, 12 volt modules)
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.

We get so-called Texas-snowstorms down here in Austin, especially in the
spring, which are basically sever thunderstorms producing hail, flash floods
and winds approaching tornado speeds. We lost a roof and some window panes
to one hail storm, and had $5k damage done to the car. A baseball-

vulnerable." IEC 61215 actually uses a 1" ice ball (what a weird thing
to use when simulating hail, right?) and shoots it at 11 points on the

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 n
