Military Engineer Services (MES) has issued a notice inviting tender for supply, erection, installation, testing, and commissioning a 1.68 MW grid-connected rooftop solar system at Ambala Air Force Station.
The project’s estimated cost is ₹94.9 million (~$1.24 million). The overall project involves the construction of a substation building and other premises with water, electricity, and other facilities. The electricity for the proposed buildings is to be procured from the tendered rooftop solar project within MES Ambala Air Force Station premises. The entire project must be completed within 15 months.
Bidders must submit an earnest money deposit of ₹799,900 (~$10,503). Successful bidders will also have the option to convert the earnest money deposit into part of the performance security. Successful bidders must furnish 3% of the contract amount as a performance security deposit within 28 days from receiving the work order.
The last day to submit the bids is April 26, 2022.
Bidders must have experience commissioning one solar project costing ₹76 million (~$998,128) or two projects costing ₹47.5 million (~$623,830). Alternatively, the bidder could have commissioned three solar projects costing ₹38 million (~$498,894).

Bidders can use either polycrystalline or monocrystalline solar modules for the project. If the bidders decide to use monocrystalline modules, they should install 3,094 modules consisting of 72 mono perc P-type solar cells of 545Wp each. The modules must be warranted for their output watt capacity, which must not be less than 90% of the initial value at the end of ten years and 80% of the initial value at the end of 27 years. The modules must have a performance warranty of more than 97.5% during the first year of installation.
The modules must perform satisfactorily in relative humidity up to 100% with temperatures between -10°C to +85°C. They must withstand adverse climatic conditions, such as high-speed wind, blow with dust, sand particles, saline climatic or soil conditions, and wind 180 km/hr on the panel’s surface.
According to Mercom’s India Solar Tender Tracker, MES has so far floated 22 MW of tenders for rooftop solar projects.
