Warranty Claim Tips
- Solar panel warranties guarantee minimum power output (typically 80% at 25 years) — monitor your production
- Microinverter warranties (25 years from Enphase) often outlast string inverter warranties (12 years)
- File degradation claims before year 25 — most expire on the installation anniversary
HomeScore Pro Tips
- SunPower and LG had the strongest degradation guarantees in the industry (92%+ at 25 years)
- A single panel replacement costs $400–$1,000 including labor — warranty saves $10,000+ over a system lifetime
- Keep your interconnection agreement and permit — they prove installation date
