The Ministry of New and Renewable Energy (MNRE) has issued a order notifying the latest benchmark costs for the installation of new grid-connected rooftop solar PV systems for the financial year 22.
After 10 days from notification, the benchmark cost for FY 22 applies to all projects to be awarded and empanelment of vendors by state implementing agencies under phase-II of the MNRE’s rooftop solar programme.
The benchmark costs include solar photovoltaic (PV) modules with domestic cells and modules and inverter (single/3 phase). The balance of the system includes cable, switches, circuit breakers, connectors, junction boxes, mounting structures, earthing, lightning arresters, civil works, installation and commissioning, a five-year comprehensive maintenance contract, transportation, insurance, and taxes. These benchmark costs do not, however, include net metering cost and battery back-up costs.
In the state other than special category the benchmark cost for rooftop projects in the rage of 10 KW-100 KW is $41.64 ($0.56)/W. This is 9.6% increased rate over the last year.
In special category states like Northeastern States, Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and the Union Territories of Andaman and Nicobar, rates for the capacities of 1kW to 2kW are at 51.67 ($0.70)/W.
Earlier this year MNRE had issued a amendments in implementation guidelines for the second phase of its Rooftop Solar Programme.
