Roof integrated solar, re: Kiley Jacques article
I am designing a house to a required 150mph wind load. I want a net zero house with PV on the roof, I have ideal orientation and no obstructions. I do want the solar panels integrated with the roof. Per the article, the ideal installation is on a standing seam roof. This may make it easy for the solar installer but seems crazy to me. First, the metal roof is expensive and will be invisible and not provide much roof protection as its covered with panels. Secondly, the use of clamps on the roofing seams places the responsibility for the structural integrity of the solar installation on the roofer! It seems to me there should be a roofing system specifically to go under solar panels that will last longer than the panels and would not need to be changed out even if the rest of the roof must be replaced. I’ve talked to roofers and solar installers about this and they best they can do is shrug their shoulders. Any good ideas out there because what we are doing is not acceptable?

This looks interesting (to me, anyway..)

Both integrate the solar capability with the roofing material.
Not sure how the slate roof helps, probably more expensive than metal and more difficult to install panels on. Tesla doesn't really seem to be serious-very expensive and no data. There should be a low cost "under roofing" for solar panels since that part of the roof does not have to deal with sun, hail, driven rain, high winds.... But thanks for the input.
If you look at the greenstone site, the design they use has an engineered under-structure, which will support either their slate, or solar panels designed to fit.
