Solar CAPEX means you own the solar plant outright. You pay the EPC firm to design, procure, build, and commission a turnkey plant on your roof or land. You get the lowest 25-year cost of energy (LCOE around ₹2.40-2.80/kWh against grid HT-I tariff of ₹7.50-9.50/kWh), full asset control, and the 40% Year-1 accelerated depreciation tax benefit. RESCO/OPEX, by contrast, has the developer own the plant; you pay per kWh consumed under a 25-year PPA at ₹4.50-5.50/kWh — zero capex but higher per-kWh cost.

Coastal sites add 5-7% for salt-protection engineering. Maharashtra projects above 100 kW from April 2026 require mandatory 50% / 2-hour BESS adding ~₹1.05 Cr per MW.
3.5-4.5 years for a typical 1 MW industrial rooftop plant on HT-I tariff of ₹7.50-9.50/kWh. The 40% Year-1 accelerated depreciation under Section 32(1)(iia) captures ₹35-40 lakh per MW in tax savings for tax-paying corporates. Net 25-year IRR is 22-28%; lifetime savings ₹38-45 Cr per MW.
