Why Use a Solar Calculator in India?
Switching to solar energy is a major financial decision. Our Solar Calculator India helps you make an informed choice by providing accurate estimates for system size, pricing, and government subsidies.

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.
