over 25 years, in today’s money

  • Generation: ~1,450 units/kW/year (jharkhand average; site-specific after survey)
  • System cost: ₹58,000/kW installed, Tier-1 mono panels, on-grid
  • Battery (if selected): ₹32,000/kWh LiFePO₄, sized at 1.5×kW (min 5 kWh)
  • Tariff escalation 5%/year; panel degradation 0.5%/year
  • O&M free for 5 years, then ₹2,000/kW/year
  • Residual grid usage assumed 5% of current bills
  • EMI: 9% APR on 90% of net cost (partner banks offer 8.5–10.5%)

We apply the current PM Surya Ghar formula — ₹30,000/kW for the first 2 kW plus ₹18,000 for the third, capped at ₹78,000 for residential on-grid systems up to 10 kW (actually 3 kW+ fetches the cap). Your final subsidy is confirmed by DISCOM on the national portal; we file it for you.

A standard setup needs ~85 sq.ft of shade-free roof per kW. If your terrace is smaller than your bill demands, we either suggest high-efficiency panels (more kW in the same area) or a two-zone design. The survey measures usable area precisely — chimneys, tanks and parapets all count.
