Key takeaways
- Manufacturer warranties cover equipment; workmanship warranties cover the installation.
- Labor is not always included in an equipment warranty. Ask who pays to diagnose and replace a part.
- Ask how service requests are submitted and what response to expect.
Types of coverage
- Product warranty: covers defects in panels, inverters and batteries, set by each manufacturer.
- Performance warranty: guarantees panels keep a stated share of their output over time.
- Workmanship warranty: covers the installer's work, such as wiring and roof attachments.
- Labor coverage: who pays for technician time when a covered part is replaced.
Service expectations to get in writing
- How to request service and who responds
- How issues are diagnosed and prioritized
- Whether system monitoring is included
- What happens if the original installer goes out of business
