"How do you think the panels would hold up to a say once in five years central/west Texas hail storm where you have golf ball size hailstones for 10 or 15 minutes with an occasional tennis ball sized one? FYI, my roofing material is cast concrete shingles and they have held up just fine for the last 25 years." It would be interesting to see a map of the US that illustrated the service factor of solar panels. For instance, I am certain Hawaii or the dry south west would have a high service factor. Here in NE Ohio I suspect the service factor would be fairly low as there are weeks on end in the winter when the roof is covered with snow and the nights are long . Also, where we live many of the homes spend much of the day in full shade. sargosis.com The issue of roof life compared to solar panel life is also interesting. Basically it would seem that a new long lived roof would need to be part of the installation process. I note there are absolutely zero homes in our area with roof solar panels. Some businesses have some - I am sure to be politically correct. Bob

Even at higher terminal velocities than when it free falls in the atmosphere at sea level. If you want you can actually buy "ruggedized" PV's. But it will cost you extra. Most tier one manufacturers make them. Eric
