Do you absolutely have to drill into your roof and shingles into your rafters or cut off a square and mount to rafters to install solar panel mounts or is there a no-drill solution for sloped roofs? I have a massive roof, built like a pyramid and I want to install some mounts to get it solar panel ready, what kind of mounts should I be looking into? Most of the videos I've seen on social media are the type that cut a small rectangle to expose the rafter to mount to it and patch. Anyone here have solar mounted on their shingle roof or have mounted racks before?
>>2873678In principle anything works as long as it holds the panels in place, you could make something out of steel that hooks over the top and is weighed down, but this relies on your roof being strong enough to handle the load. The picture you posted is specifically from one such system so you should probably know about it. The best solar panel mount is always ground, if you have space on the ground then maybe consider spamming them there.
I/we used Unirac. didn't choose it. it's just was the guy who sold us our original setup carried. I have no complaints. it does what it is built for. it has been installed on two different roofs. two years on our old house, 5 months on our solar shed at new house. it has withstood 120kmh winds, sustained.it is the opposite of what you are looking for, but it may be the answer, regardless. it has 4 mounting brackets anchored to rafters, through composition shingles & tar underlayment for our entire array. have never had a leak.
