What this calculator is for

  • • A first-pass comparison using the consumption, tariff, offset, size and financing inputs you choose.
  • • Understanding how assumptions affect system size, annual generation, savings and payback.
  • • Preparing questions before requesting an EPC, RESCO or financing proposal.

What still needs site validation

  • • Interval load, self-consumption, demand charges, time-of-day tariffs and export settlement.
  • • Usable roof area, structure, shading, electrical interconnection, approvals and shutdown requirements.
  • • Current equipment offers, taxes, depreciation treatment, financing, degradation and O&M costs.

Visible screening defaults: 3.5 kWh/kWp/day generation, ₹40,000/kWp base installed cost before the modelled GST, ₹500/kWp Year-1 O&M, 3% tariff escalation, 5% O&M escalation and 0.5% annual degradation. Change user-controlled inputs and treat every default as a sensitivity, not a market quote.

Results are indicative screening estimates, not a quote, engineering design, tax opinion or savings guarantee. Validate the model with current bills, interval load, site data, quotations, applicable regulations and professional advice before investment.
