Enerture Technologies, Independent Business Machines, Success Impex, and Sunlive Solar have won Chandigarh Renewable Energy and Science & Technology Promotion Society’s (CREST) tender to build and operate grid-connected rooftop solar projects on government-owned residential buildings.

The tender for 4 MW rooftop solar projects varying from 2 kW to 5 kW in Sector-1 to Sector-20 of Chandigarh was distributed equally between the four winners at the lowest quoted tariff of ₹58,000 (~$699)/kW on a turnkey basis.

The scope of work includes design, manufacture, supply, erection, testing, and commissioning, including warranty, operation, and maintenance. The completion period for the project is three from the order to commence the work.

Only domestically produced solar modules from the Approved List of Models and Manufacturers must be used in the projects.

The modules must be guaranteed for 25 years, while all other equipment is to be guaranteed for ten years. This guarantee must cover unsatisfactory performance or breakdowns due to defective design, workmanship, or materials.

The rooftop solar projects will be considered finished once the installation is done and bi-directional meters are tested.

Additionally, the project completion report must be signed by CREST, the third-party inspection agency, and the bidder. The contractors are required to sign the agreement within 15 days of acceptance of the tender.

Last year, CREST invited bids to commission a 1 MW rooftop solar project at the parking area near DT Mall and 5.5 MW floating solar projects with power evacuation at Water Works in Sector 39, Chandigarh.

The agency also invited bids to commission a 4 MW grid-connected canal top solar power project with power evacuation in Sarangpur, Chandigarh, last year.
