## Thirty-year yield

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

- **Cumulative output, JKM580-605N-72HL4-(V) 605W:** 20,299 kWh
- **Cumulative output, JKM615-635N-78HL4-(V)-F6-EN (620W variant):** 20,802 kWh
- **Gap:** 503 kWh
