## 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, CHSM66N(DG)/F-BH-730:** 24,493 kWh
- **Cumulative output, CHSM72N-HC-570:** 19,125 kWh
- **Gap:** 5,368 kWh
