This calculator follows the calculation assumptions supplied by B&B Green Energy. The 3 kW on-grid price is ₹2.33 lakh and 5 kW is ₹3.50 lakh. Intermediate and larger capacities are estimated by interpolation/extrapolation for calculator purposes and should not be treated as a final quotation. Hybrid pricing is not calculated because no hybrid price schedule was supplied.

Calculation method

How the Estimate Is Calculated

Solar Generation1 kW = 4 units/day. Therefore 3 kW = 12 units/day = 4,380 units/year. 10 kW = 40 units/day = 14,600 units/year.

Domestic SavingsAnnual solar units × ₹8. Example: 3 kW = 4,380 × ₹8 = ₹35,040 estimated annual electricity value.

Commercial SavingsAnnual solar units × ₹10. Example: 3 kW = 4,380 × ₹10 = ₹43,800 estimated annual electricity value.
