SOLAR / HOMEOWNER GUIDE
Solar warranties: who fixes it and who pays?
A replacement part does not always mean a free repair. Find out who pays for diagnosis, labor and removal when solar equipment fails.

Start here.
Solar equipment and installation can have separate warranties. Ask who handles the claim and whether diagnosis, shipping, removal and reinstallation are covered. A panel output warranty is not the same as a whole-system production guarantee.
Create a responsibility list.
For each major component, record the company providing coverage, how long it lasts, what it excludes and whom to call. Separately identify coverage for installation work and leaks around roof attachments. Ask for the actual documents tied to the proposed models.
Ask about labor and access.
A replacement part does not necessarily cover diagnosis, removal, shipping, reinstallation or travel. Request an explanation of those costs. If panels must be removed to reach a failed component, ask how that work is treated.
Separate output promises from equipment coverage.
Ask whether the offer contains a panel performance warranty, a system-production guarantee or neither. Identify how a shortfall would be measured and what remedy is available. Those terms should not be inferred from a savings chart.
Discuss future changes and ownership.
Ask how roof replacement, equipment upgrades or selling the home affects warranty and service arrangements. For leased or financed equipment, keep ownership and lender terms separate from manufacturer coverage. A transfer process may involve more than updating an app login.
Solar installer out of business? Start with the paperwork.
An unavailable installer does not tell you whether a separate manufacturer warranty applies. Find the original contract, equipment models and serial numbers, installation date, registration records and any previous claim numbers. Contact the manufacturer through its official support channel to confirm the applicable terms and claim process.
Ask whether another qualified provider can carry out approved warranty work and which charges would remain yours. Do not authorize a repair on the assumption that labor, travel or roof access will be reimbursed. Get claim approval and any reimbursement limits in writing.
If you lease the system or have a power purchase agreement, check with the system owner before arranging changes. If you bought the home with solar, ask about account access and any required warranty transfer. We do not take over the original installer’s workmanship obligations.
