How CAPEX, open access, RESCO and zero-investment solar work in practice.

Three Ways to Go Solar

Each case study walks through the structure, cash flows and indicative economics. Figures are illustrative — we model your exact case during feasibility.

CAPEX · Open AccessHaryanaIllustrative

Build Anywhere in Haryana, Use It at Your Factory: 2 MWp Captive Solar via Open Access

A Gurugram manufacturer owns a 2 MWp ground-mounted plant in south Haryana and wheels the power over the grid to its factory, paying regulated charges.

RESCO · PPAGurugramIllustrative

RESCO for a Commercial Building: Pay Only for the Solar Units You Use

A commercial complex hosts a 400 kWp rooftop plant owned by the developer and buys the power at a fixed tariff well below the grid rate.

Zero InvestmentNCRIllustrative

Zero Investment, Full Ownership in ~6 Years: 300 kWp for a Manufacturing Unit

A factory installs 300 kWp with no upfront payment, pays a solar tariff below grid rates for ~6 years, then owns the plant outright.
