What Insurance Does a Solar Installation Business Need in the USA?
Solar installation involves rooftop work, electrical connections, and significant installed asset values – all of which create specific insurance requirements that differ from general contractor coverage.
Essential Solar Contractor Insurance
General Liability (minimum $1M/$2M): Covers property damage and third-party injury. Critical for solar: ensure your GL policy does NOT exclude roofing work – many standard contractor policies do, and installing panels requires walking on roofs.
Workers Compensation: Legally required in most states with employees. Solar work is high-risk (rooftop, electrical) – premiums reflect this. Budget 8-15% of payroll for WC in solar.
Commercial Auto: Required for vehicles used in business. Solar requires hauling panels and equipment – ensure your policy covers the cargo weight.
Errors and Omissions (E&O): Also called professional liability. Covers claims arising from design errors – wrong system sizing, shading analysis errors, production guarantee disputes. Increasingly required by larger commercial solar clients.
Installation Floater: Covers equipment and materials before they’re permanently installed. A pallet of solar panels sitting on a job site overnight is not covered by standard GL.
The Roofing Exclusion Trap
Many contractors discover too late that their general liability policy excludes “roofing work.” Inspect your policy carefully – and specifically ask your broker: “Does this policy cover work performed on or near rooftops, including solar panel installation?”
