How we calculate this
  • Generation: about 1,500 units per kW per year in Chandigarh, varying by month as shown in the chart.
  • Roof space: about 90 sq ft of shade-free roof per kW.
  • Price: typical installed cost of ₹52,000 to ₹65,000 per kW for homes and ₹48,000 to ₹55,000 per kW for businesses, depending on size. Your quote depends on brands, structure height and wiring.
  • Subsidy: PM Surya Ghar pays homes ₹30,000 per kW for the first 2 kW and ₹18,000 for the third, up to ₹78,000.
  • Savings: units you'd otherwise buy, at your current rate. Panels are assumed to lose 0.5% output a year, with no tariff increases, so long-term savings are likely understated.
  • CO₂: 0.71 kg per unit, India's average grid emission factor.
