Solar in Troy
Troy's Building Department issues the city's electrical permits itself and keeps an inspection line, 248-689-5744, open from 8 AM to 2 PM. Its contact box number is 248-524-3344, per the city's page. The electrical section of the 2026-27 fee schedule lists generators and general items but no photovoltaic row, and the only solar line sits under mechanical permits, so ask the department what a PV electrical permit costs. Troy's electric utility, per the MPSC territory map, is DTE Electric alone.
You'll want to confirm the address with DTE anyway. DTE puts the interconnection process at approximately six weeks. After it approves an application, the installer has 180 days to install the system and upload an approved electrical inspection sticker, and the sticker comes from the local inspection, which in Troy means the Building Department's inspectors. So the inspection is a step the utility waits on. When the work is done, the 8 AM to 2 PM line is where the inspection gets booked, and that sticker is what lets DTE finish its side.
