## Thirty-year yield

A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year

Same temp coeff. for both panels (-0.260 %/°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, A470-MAH54Mb:** 15,769 kWh
- **Cumulative output, A795-GRH78Dw:** 26,674 kWh
- **Gap:** 10,905 kWh
