In July this year, ANERT invited bids for the design, supply, installation, and commissioning of 20 MW of grid-connected rooftop solar systems with capacities of 2 kW to 30 kW under various programs in Kerala.

Mercom India Research found that government agencies across India floated solar tenders totaling 14 GW in the third quarter (Q3) of the calendar year (CY) 2022, an increase of 56% compared to the previous quarter.

According to Mercom’s India Solar Tender Tracker, ANERT has floated 53 MW of rooftop solar tender to date.
