Solar Repair Costs: What Repairs Actually Cost (2026)

Inverter replacement: the big one

String inverters last 10–15 years and cost $1,500–$3,500 installed to replace. Microinverters last longer (20–25 yrs) and cost $200–$400 each if one fails. Budget for one inverter replacement during a 25-year system life.

Panel and other repairs

Replacing a single panel costs $500–$1,500 (parts + labor). Hail or debris damage on a few panels is usually covered by insurance minus deductible. Electrical faults, rapid-shutdown devices, and monitoring hardware are smaller but real costs.

Warranty is the difference

Most repairs are covered under equipment warranties (25 yr panels, 10–25 yr inverters) and workmanship warranties (10–25 yr). Out-of-pocket costs are mainly for labor on non-covered items and post-warranty failures. Read your warranty before it matters.
