Vyomaa Energy and Sunanda Solar Energy have won Solar Energy Corporation of India’s (SECI) auction to install 2,112 kW of grid-connected rooftop solar systems under the renewable energy service company (RESCO) mode.

Vyomaa will install 335 kW at a tariff of ₹4.47 (~$0.051)/kW at the International Centre for Genetic Engineering and Biotechnology, Delhi, and 1,200 kW at a tariff of ₹4.19 (~$0.048)/kW at the National Institute of Technology, Calicut.

Sunanda will install 177 kW at a tariff of ₹4.43 (~$0.051)/kW at the National Sanskrit University, Tirupati, and 400 kW at a tariff of ₹3.62 (~$0.041)/kW at the National Institute of Technology, Raipur.

The tender was floated in December last year.

The Scheduled Commissioning Date (SCD) for projects’ full capacity will be nine months from the date of the power purchase agreement(PPA). The maximum time allowed for commissioning the full project capacity, with applicable penalties, will be up to six months from the SCD or the extended SCD.

The successful bidders must obtain a no-objection certificate from the distribution company concerned for grid connectivity, as well as the design, engineering, supply, storage, civil work, erection, testing, and commissioning.

They must operate and maintain the solar systems during the duration of the PPA. Only commercially established and operational technologies must be used to minimize the technology risk and achieve timely system installation.

The modules used in the project must be included in the latest Approved List of Models and Manufacturers issued by the Ministry of New and Renewable .

In the first quarter of 2015, India added 1.2 GW of rooftop solar capacity, up 232% year-over-year from 366.5 MW. Installations declined 6.2% from 1.3 GW in the previous quarter, according to Mercom India Research’s newly released Q1 2025 India Rooftop Solar Market Report.

In April, SECI issued a request for selection to develop grid-connected rooftop solar projects with a cumulative capacity of 6.25 MW. These projects will be implemented on a build-own-operate basis.
