Warranty Claim Process
The steps to file a manufacturer warranty claim for defective solar panels, inverters, or batteries: document the issue, contact manufacturer, obtain RMA number, arrange replacement, and handle reinstallation labor.
Why It Matters
Labor to remove and reinstall a defective panel costs $200-500, which panel warranties rarely cover. Some installers offer workmanship warranties that fill this gap.
Related Terms
Production Guarantee
A written guarantee from a solar installer specifying the minimum kWh of electricity the system will produce annually. If actual production falls short, the installer compensates the difference.
Degradation Rate
The annual decrease in solar panel efficiency. Modern panels typically degrade 0.3-0.5% per year.
