The size of each project shall be in the range of 25 kWp to 500 kWp only. One project may, however, comprise several rooftop units, each of which may separately connect with the grid and have separate meter.
A single developer can bid for minimum 1 MWp and maximum 10 MWp capacity.
The fixed ceiling tariff under gross metering for over 25 years shall be the weighted average tariff of large-scale solar projects of 5 MW and more, discovered through competitive bidding in the previous financial year and adopted by the commission plus an incentive of 25%.
