☀️ PV Generation Estimator

enter installed capacity、annual equivalent full-load hours and system efficiency，estimate first-year and lifetime generation，and convert to annual reduction CO₂。for rooftop distributed and ground-mount pre-feasibility。

installed capacity (kWp)

annual equivalent full-load hours (h/year)

system efficiency PR (%)

project lifetime (year)

first-year degradation (%)

average annual degradation (%)

result

— kWh / first year

No. 25 year-end annual generation—

formula：first-year generation = capacity × full-load hours × PR÷100；No. k year = first year ×(1−first-year degradation)×(1−average annual degradation)^(k−1)，total generation accumulates year by year。
CO₂ emission factor defaults to 0.581 kg/kWh（national grid average），standard coal at 1.4 tstandard coal/tCO₂ rough conversion。
