How Manual Calculation Works

If you want to do a rough calculation yourself, here is the formula used by solar installers in India:

System Size (kW) = Monthly Units Consumed / 120

For example, if your bill is for 480 units, you need approximately 4kW of solar capacity (480 / 120 = 4kW). However, roof area and shadow analysis are also crucial factors that our advanced calculators take into account.
