How the Calculator Works

Our calculations use real satellite data, current subsidy rates, and component-wise EPC pricing.

1

Location-Based Sizing

We fetch your area's Global Horizontal Irradiance (GHI) from NASA POWER satellite data, then size the system using: System kW = (Daily Units / 30) ÷ (GHI × 0.80 PR).

2

Component-Wise Pricing

Cost is calculated per component — panels, inverter, ACDB/DCDB, structure, cabling, installation, and MSEDCL liaison — not a flat per-kW rate.

3

Subsidy & Payback

PM Surya Ghar subsidy is applied automatically. Payback accounts for 0.5% annual degradation and 2.5% tariff escalation over 25 years.
