Small businesses are open to adopting rooftop solar if loan repayment is not an additional burden and is equal to their savings on electricity bills. Entities in the commercial and industrial segment are increasingly moving towards renewable energy options, including rooftop solar, given the immense benefits they bring in terms of cost savings and reputation as sustainable companies. Vikas Agarwal, the co-founder of non-banking financial company Credit Fair, said in an interview with Mercom India that there is an uptick in rooftop installations in the residential segment after the Union government launched a national portal for rooftop solar to submit applications.

Sterlite Power has bagged an interstate transmission system project for the evacuation of 20 GW of power from renewable energy zones in Rajasthan under Phase III, Part-G. The company participated in tariff-based competitive bidding and was awarded the letter of intent by PFC Consulting, a wholly-owned subsidiary of Power Finance Corporation, to build the project on a build, own, operate, and transfer basis for 35 years. The project comprises the construction of a 765 kV transmission corridor which will be laid across a 350 km stretch from Fatehgarh III to Beawar in the Ajmer district.

Gujarat Urja Vikas Nigam (GUVNL) has invited bids to procure power from 500 MW of grid-connected wind projects (Phase V) with a greenshoe option of an additional capacity of up to 500 MW. The last day to submit the bids online is April 11, 2023. Bids will be opened on April 17. GUVNL will enter into a PPA with successful bidders for 25 years from the scheduled commercial operation date of the project or the date of full commissioning of the project, whichever is earlier.

Union Minister of Renewable Energy and Power R. K. Singh informed the Rajya Sabha that the government aims to reduce a total of ₹1 trillion (~$12 billion) worth of fossil fuel imports by 2030, following the targets set under the National Green Hydrogen mission. The minister said nearly 50 million metric tons of carbon emissions are likely to be mitigated through the production and use of green hydrogen.

The European Union has unveiled two key initiatives to make the transition to clean energy and ensure it has access to critical raw materials to make the switch. The measures are expected to enable the bloc to counter the competition from the United States and China on the clean energy front. The first of these initiatives announced by European Commission President von der Leyen as part of the Green Deal Industrial Plan is the proposed Net-Zero Industry Act that promotes the scaling up of clean technology manufacturing.

Italy-based renewable energy company Enel Green Power, researchers at the National Solar Energy Institute, and the French Alternative Energies and Atomic Energy Commission claimed to have achieved a power conversion efficiency of 26.5% for a 2-terminal tandem perovskite solar cell. The improved efficiency in the collaborative research was obtained for a PIN architecture cell in the device with an active area of 9 cm² and an open-circuit voltage of over 1,880 Mv, with shading correction.

Researchers at Helmholtz-Zentrum Berlin have found that solar cells made of metal halide perovskites achieve high efficiencies and can be produced from liquid inks with little energy input. Metal halide perovskites are a particularly inexpensive and promising material class for next-generation solar modules. Perovskite solar cells can be fabricated using coating processes that use liquid inks made from precursor materials and various solvents. After the coating, the solvents evaporate, and the perovskites crystallize into a homogeneous layer.
