Installing Solar Panels on a Roof With Exterior Rigid Foam
I have a recent retrofitted passivHaus built in the Bronx, NY with new architectural shingles over a quarter inch thick plywood and 4 inch ridgid foam boards on top with another quarter inch plywood sitting on top of the old existing roof.
I’m now seeking to install solar panels but with all my engagements with local PV installers they don’t seem to have the ability or confidence to find a way to install/anchor the panels to my roof. 1. The PV installers seem to all agree they need to anchor the brackets to the rafters but how can they find it on one go without making my roof into Swiss cheese is the concern.
Do anyone know 1) best way to install solar panels to passivHaus post construction with at least 4 inches of exterior ridge foam boarding? 2) PV installers in NYC who can help? 3) install method?
Note: I am not the architect but the owner of the passivHaus.
I’ve also saw the Q&A below but the info seem to be stale since 2016 entry.
