## 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, JKM735N-66HL5-BDV-Z3-EU:** 24,661 kWh
- **Cumulative output, JKM450-475N-48HL4M-DB-Z2-EN (475W):** 15,937 kWh
- **Gap:** 8,724 kWh
