Telangana State Renewable Energy Development Corporation (TSREDCO) has invited bids to install and commission 3.07 MW of grid-connected rooftop solar systems of various capacities with net metering at 1,521 government schools across Telangana.

The projects will be developed under the capital expenditure (CAPEX) model.

The average annual turnover of bidders should not be less than ₹50 million (~$628,770) during the last three financial years.

The solar modules should have a minimum capacity of 250W, and the efficiency of the modules should be at least 16%.

All solar modules should carry a performance warranty of >90% during the first ten years and >80% during the next 15 years. They should carry a performance warranty of >97% during the first year of installation, and the degradation of modules should be below 1% per annum.

In February this year, TSREDCO invited bids to empanel vendors to install 50 MW of grid-connected residential rooftop solar projects under Phase II of the grid-connected rooftop solar program of the Ministry of New and Renewable Energy.

Earlier, TSREDCO had floated an empanelment tender for 1-10 kW capacity of residential rooftop solar projects.

According to Mercom’s India Solar Tender Tracker, TSREDCO has issued tenders for 64 MW of rooftop solar capacity to date.
