## 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, NT12R/48GDF-455W:** 15,266 kWh
- **Cumulative output, JKM450-475N-48HL4M-DV (470W class):** 15,769 kWh
- **Gap:** 503 kWh
