## Thirty-year yield

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

Same temp coeff. for both panels (-0.300 %/°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, 450 Wp HC NE:** 14,070 kWh
- **Cumulative output, 450Wp HC NE (G/G-TC):** 14,070 kWh
- **Gap:** No difference
