Engineering Formula

E_m = f_m × E_annual with Σf_m = 1.0

Uses a typical Indian PV monthly-share vector derived from NASA POWER 22-year mean. Substitute local irradiance data for site-specific splits.

Step-by-step Calculation

1.TotalΣ Em15,000 kWh

Design Assumptions

• Distribution valid for lat 20–30 °N, south-facing tilt≈latitude.

Engineering Tips

◆Replace fractions with PVsyst PA report for bankable studies.

Warnings

▲Monsoon months (Jul-Aug) may drop 20–30% vs this baseline.
