Solar panels and roof leaks ?

Apparently 25mm is a standard size iceball to shoot at solar panels in the lab. Which is basically golf ball size. Bigger hail than that, they might not be tested...

Glad I don't live where the hail is that big.

My system was up for over 10 years and a great many storms. I never measured the biggest of the hailstones we had, but Austin has actual hail and several neighbors lost roofs because of it. I never lost a single panel and only a couple of shingles.

Solar panels have long been designed to survive hailstorms.
 
Here is a new solution by Tesla, a solar roof, the shingles are actually solar panels. Don't know cost or availability in any particular area. Anyone have experience with these?
"Solar Shingles" have been out for ages. They're a great look, but they are less efficient and productive than traditional panels.

If companies would start producing panels with architectural shapes I think people would be less opposed to them. That would also require homes be constructed with vent stacks planned better.
 
See a lot of the solar panel's installed on existing roofs . Just wondered are roof leaks a big issue with panels being mounted on roofs ?
It is mostly about workmanship. If the installers know how to make it waterproof, it is not an issue. If you hired the low bidder, it might become a problem down the road.

A hailstorm in San Antonio a few years ago did major damage to a big ground mounted PV system there.
 
I've always wondered, what happens when one of these hail storms goes over top of like a car dealership?
Seen it, hundreds of thousands in damage on the large lots, thousands on the smaller lots. Have a friend that got a great deal on a new BMW that had a little hail damage, about 1/3 to 1/2 off the MSRP.

I had a Fiero GT once upon a time. A huge hailstorm came through at work and a bunch of us went out on the porch to watch the carnage.

I'm thinking my car won't have any damage until a hailstone cracked one of the fake window things. A friend's car didn't fare as well. His car came out of it looking not unlike a golf ball and was totaled as a result.

That kind of storm isn't unheard of in Texas and I never, not once, saw a panel get damaged. One of the things I believe will revolutionize solar production, especially in urban areas, is using panels as construction material - covered walks, parking lots, any place where it would be nice to have a bit more protection from the sun and rain is a place where solar panels belong.

I sure have. We had a bunch of residential modules to replace in San Antonio when that storm went through there that took out so many of those ground mounted ones I mentioned earlier. Our worst commercial hail damage was on a rooftop system up in Dallas. That was a Solyndra system (remember those?); about a third of the modules had at least one broken tube, and that's when we found out about the slippery fluid the tubes had in them. The roof membrane was TPO and there was broken glass and that fluid all over the roof; it was a greasy mess up there.

Interesting. When I worked for the commercial monitoring place we didn't have projects in the big hailstorm areas. I think we might have had one small project in Austin. Most were in the Northeast.

Everything is bigger in Texas. :D

Our solar projects weren't. Most of the renewable energy in Texas is actually wind farms.

I got involved in all things renewable energy related in '07 or so after I read a paper about how no more than 5% if the grid could be powered by renewables, because "reasons". What's funny about Texas is it's supposedly anti-renewable-energy but 1/3rd or more of the power comes from wind on a pretty regular basis.
 
When I saw your post I was like “he did what I’m contemplating”.

How did you tie your horizontal gutters in?

I like the idea of being able to repair things from below.

Would this support need to engineered to get approval for a permit ?
 
The roof of my home is not really ideal for modules, a small house and a hip roof so not a lot of area on a roof plane. I am putting a shade structure up over my patio and am thinking of just mounting the models on that. Shade and module mounting at the same time.

Only your local building department can answer that. Although personally if I were the plan checker, I would probably say yes, because that wood construction doesn't look strong against high winds and I wouldn't want the panels flying onto the neighbors' property.

They told me since I wasn’t placing modules on a barn, Shed or dwelling I didn’t need a permit. I see your point though. I’m in the country where my neighbors aren’t close so I’m not worried about modules flying off and damaging anything. I would be more worried about the whole thing flying away than an individual module coming loose. They’re secured very well in my opinion. I’ve observed them through some serious wind storms and I feel good about the structure.

Out here Tesla is not pushing orders for new roofs and there seem to be ongoing problems with existing installations. Excessive enthusiasm.
 
Ah yes, goop and a prayer. I remember those days.
It wasn't that horrible. Done properly it produced leak-free roofs. Done poorly, because too many new installers didn't take the time to do it right, it resulted in a ton of leaks.

Hi all,

I just got my solar panels installed from Solar City a couple of weeks ago. Last week we had a lot of rain and while i was in the attic putting away Christmas decorations I noticed a small leak near to where my solar panels were mounted.

Solar City originally cleared the installation after the final inspection, since they saw the roof and shingles were fit for the new installation but it seems like during the installation there was a crack in the sheathing with either people walking on the roof or some hole that was drilled for the mounting pucks.
roof repair falls church
I called customer service and I have an appointment for tomorrow morning for someone to inspect the leak.

Does anyone have any experience with Solar City and how the deal with these kind of issues? I saw a post from someone else having similar issues and SC ended up subsidizing part of the roof.
