What it means on a roof
Thirty years of production
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 (-0.370 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
