We keep our RV in covered storage so hail is not a big problem for us, but we have been camping when it has hailed and we had a nasty hail storm hit us a couple of weeks ago when the RV could have been at our house in preparation for a trip. That hail storm had large hail which tore holes in the cover on our backyard pool so we began to wonder what damage hail might do to solar panels.
Our Fuse has 2 flexible solar panels on the roof. Would those be damaged by hail? We are planning to add a 3rd panel and that could be another flexible panel or it could be a rigid one. Are the rigid panels more or less susceptible to hail?
Hailstones up to a diameter of an inch with a speed of 50mph should not be a problem. This is a part of the testing parameters that every solar panel product has to pass (IEC 61215 standard). Regarding the speed and diameters of most hail storms & stones so we can say that 95% of the hailstorms don't damage the solar panels (you probably get more damage on your RV than on the solar panels). Nevertheless: Huge storms with hailsstones with a diameter of a fist damage everything.
Fortunately, when we have hail (very seldom) it is about pea sized! I have never had hail damage to vehicles, house, RV or solar panels! I hope this trend continues when I move my home base to Kentucky!
I live in the Phoenix area of southern Arizona and you would not think that we would have a hail problem in this area but a couple of months ago we had a hail storm with hail about the size of ping pong balls and it hit with enough force to tear holes in our pool cover. That was the reason for the posting.
Hail is pretty uncommon here, as you might expect, but we have seen it a couple of times in the last 10 years. We generally keep our RV in covered storage so that is not the problem. I was just wondering if the solar panels on our RV were likely to be damaged by hail if we ran into it in the future.
