In June last year, CREST invited expression of interest (EoI) from engineering, procurement, and construction companies (EPC), manufacturers, and system integrators to set up grid-connected rooftop solar systems of 1 kW to 10 kW in Chandigarh.

Earlier, CREST had invited bids for setting up 2 MW (varying from 2 kW to 100 kW) of grid-connected rooftop solar systems at various government buildings and institutions in Chandigarh.

According to Mercom’s India Solar Tender Tracker, CREST has issued tenders for 13 MW of rooftop solar projects to date.
