Calculate Your Solar System Requirement
Find out your required solar capacity, number of panels, roof area, and government subsidy benefits in seconds.
Formula
Daily Unit Consumption = Total Units Consumed ÷ Number of Days
Required Solar System = Daily Unit Consumption ÷ 3.5
Number of Solar Panels = Required Solar System ÷ 0.59
Total Panel Capacity = Number of Panels × 0.590 kW
Required Roof Space = Number of Panels × 32 sq.ft.
Total Cost Before Subsidy = Total Panel Capacity × ₹70,000/kW
Required Load = Required Solar System ÷ 0.85
Subsidy:
1 kW to 2 kW = ₹30,000
Above 2 kW to 3 kW = ₹60,000
Above 3 kW = ₹78,000
