What drives the cost of commercial solar installation in ST Clair

  • Racking type: ballasted, attached, ground or carport

Before you hire in ST Clair

Lead-safe work rules apply to most homes

The typical home in ST Clair was built around 1959. Painting, window, siding and remodeling work that disturbs paint in homes built before 1978 must follow the EPA lead-safe (RRP) rule. Ask any contractor for their RRP certification before work starts.

Older plumbing and sewer lines

51% of homes here were built before 1960, when cast iron drains, clay sewer laterals and galvanized supply pipe were standard. A sewer camera inspection before buying or remodeling is cheap insurance.

Permits: check with the ST Clair building department before work starts.

Commercial Solar Installation in ST Clair: FAQ

It depends on system size, roof or site conditions, electrical and switchgear work, interconnection requirements, racking type and the ownership model. Compare proposals on the same scope.
Yes. Commercial solar needs an electrical permit and usually a building permit with engineered drawings. In Detroit, BSEED issues these permits.
Many can, but a structural review is required. Ballasted systems add weight, while attached systems add roof penetrations, so the roof age and structure decide the approach.
