Calculation
P = A · G · η
Area, irradiance and efficiency multiply; temperature and inverter losses reduce real output.
P = A·G·η

Result
Select a target and calculate.
Understand the inputs
- PV peak power P — Electrical DC power at assumed irradiance.
- Module area A — Active module area.
- Irradiance G — Solar irradiance; 1,000 W/m² is STC.
- Module efficiency η — Share of irradiance converted to DC power.
Example
10 m² · 1,000 W/m² · 20% = 2 kW.
Assumptions and limits
Uniform irradiance and cell temperature; shading and system losses are excluded.
