BrightGridSolar systems contain several components, and each component can have different warranty terms. Understanding what each warranty covers is important when comparing installation proposals.
Solar panel product warranty
The product warranty generally covers manufacturing defects or faults in the panel itself. The length and conditions vary between manufacturers.
Solar panel performance warranty
A performance warranty sets expectations for how much generating capacity the panel should retain over time. Solar panels gradually degrade rather than suddenly stopping at the end of the warranty period.
Inverter warranty
The inverter has its own warranty and may have different coverage from the panels. Since inverters contain electronic components, their expected service life can differ from that of the panels.
Battery warranty
Battery warranties can include time limits, cycle limits, throughput conditions or minimum retained capacity requirements. These terms should be reviewed carefully.
| Warranty | What it generally covers |
|---|---|
| Panel product | Manufacturing defects |
| Panel performance | Long-term output expectations |
| Inverter | Inverter faults subject to terms |
| Battery | Battery performance and specified conditions |
| Installer workmanship | Installation-related workmanship |
Do not compare warranty years alone
The conditions attached to a warranty can be just as important as the headline number of years.
