The short answer: ₹3 crore to ₹4 crore, all-in, for a CAPEX-owned 1 MW solar plant in India in 2026 — using Tier-1 N-type TOPCon bifacial modules rated 625 Wp or higher, Tier-1 100 kW string inverters, full Balance of System, installation, commissioning, and composite GST at.

Large-scale solar project costs in India increased for the second consecutive quarter, according to Mercom's Q1 2025 India Solar Market Update, average project costs rose 3% quarter-over-quarter (QoQ) and 1% year-over-year (YoY). The average selling price (ASP) of Indian-made DCR-compliant modules. The average cost of large-scale solar projects in India dropped by almost 23% year-over-year (YoY) in the third quarter (Q3) of calendar year (CY) 2024, according to Mercom India Research's recently released Q3 2024 India Solar Market Quarterly Update. The costs remained flat quarter-over-quarter. India's solar photovoltaics (PV) market is rapidly growing. However, to reach the ambitious goal of 500 GW of renewable energy by 2030, there is a pressing need to increase installed capacity and generation targets. With only around 62 GW of installed solar capacity achieved by the end of 2022. Here's a detailed guide to the solar power plant setup cost in India, including major cost components, size‐based estimates, factors affecting cost, subsidies & financing, plus a sample calculation. If you want, I can also prepare a version specific to your state or district (Ahmedabad / Gujarat). The results reveal that higher module efficiency and greater solar irradiation significantly bring down the cost of Solar projects, bringing it even below the global average LCOE of solar PV of 49$/MWh for higher efficiencies and reducing the payback period to as low as shorter than 5 years.
