The Ministry of New and Renewable Energy (MNRE) in India offers a number of subsidies for solar power projects. The amount of subsidy available depends on the project size, location, and other factors.

For rooftop solar projects, the MNRE offers a central financial assistance (CFA) of 30% of the benchmark cost or the tender cost, whichever is lower. The state government may also offer an additional subsidy. For example, the state government of Maharashtra offers a subsidy of up to 30% for rooftop solar projects.

For solar projects in rural areas, the MNRE offers a CFA of 50% of the benchmark cost. The state government may also offer an additional subsidy. For example, the state government of Gujarat offers a subsidy of up to 30% for solar projects in rural areas.

For solar projects in off-grid areas, the MNRE offers a CFA of 70% of the benchmark cost. The state government may also offer an additional subsidy. For example, the state government of Uttar Pradesh offers a subsidy of up to 30% for solar projects in off-grid areas.

The MNRE also offers a number of other subsidies for solar power projects, such as subsidies for solar water pumps and solar street lights.
