Electricity Bill Savings Calculator
Enter your monthly units and roof area to see the system size, generation and share of your usage solar could cover.
Shown on your electricity bill.
Assumptions and formulas
4 peak sun hours/day, 80% system efficiency, 550 W panels, 10 m² per kW (flat roof) or 8 m² per kW (sloped roof), 0.5% yearly output decline. Monthly generation = kW x 30 x 4 x 0.8. Rupee savings, cost, subsidy and payback are shown as ₹X00 because they depend on your tariff, quote and scheme eligibility. Use the ROI calculator with your own quote to compute them.
Disclaimer: results are illustrative estimates based on the assumptions above, not a quotation or guarantee. Actual generation depends on your site, shading, season and equipment.
Reading the result
Solar offsets units, not fixed charges. Your bill will usually fall but not vanish, and the exact rupee saving depends on your tariff slabs and DISCOM rules.
