## 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, JAM54D40-460/LR:** 15,434 kWh
- **Cumulative output, JKM465N-48HL4M-BDV-Z2-EU:** 15,602 kWh
