What a mounting structure does
DOE says PV arrays "must be mounted on a stable, durable structure that can support the array and withstand wind, rain, hail, and corrosion over decades." DOE says these structures "tilt the PV array at a fixed angle determined by the local latitude, orientation of the structure, and electrical load requirements."
Roof repairs after installation
For lease and PPA bids, the FTC says to compare "what happens if you need to repair your roof after the system is installed." Whatever you choose, get the answer in writing.
Leaks and the roof
We do not diagnose leaks. Read what the contract and the warranties say about the roof and the installation workmanship.
When a lease ends
The FTC says that after a lease ends, "the company must remove the system and put your roof back in its original condition."
Stay off the roof
Roof work involves fall hazards. Do not go on a roof based on anything on this site. Use licensed or registered professionals as your state requires.
