Uttar Pradesh Power Corp. Ltd. (UPPCL) has launched a tender for the selection of developers to supply energy from 1,500 MWh (375 MW x 4 hours) of standalone battery energy storage systems (BESS) in the state of Uttar Pradesh, on an on-demand basis.

Saatvik Green Energy Ltd has announced the launch of its initial public offering (IPO), aiming to raise INR 900 crore. The offer comprises a fresh issue of equity shares aggregating up to INR 700 crore and an offer for sale (OFS) aggregating up to INR 200 crore by the promoters.

Scientists in Belgium have investigated how perovskite absorbers used in solar cell degrade under three different stress test types and have found that the interface between the perovskite layer and the electron transport layer suffers from weak thermomechanical stability, which creates the conditions for performance losses.

The Ministry of New and Renewable Energy (MNRE) has proposed the inclusion of solar wafers under the Approved List of Models and Manufacturers (ALMM), in a move aimed at promoting domestic manufacturing across the entire solar cell value chain. The ALMM for solar wafers will come into effect on June 1, 2028.

Researchers in Spain investigated effective separation of encapsulants from PV glass with a focus on melting behavior and resistance to the hot knife-method of delamination. The results indicated that thermoplastic polyolefin encapsulants were the easiest to remove from the PV glass.

Researchers in China have investigated four strategies that minimize TOPCon solar cell surface recombination centers and improve light trapping performance. They identified alkali polishing with micro-texturing as the most suitable technique to improve TOPCon cell open-circuit voltage and fill factor and the overall device performance.

Polycab has launched its UT Series 350kW three-phase string inverter for utility-scale solar projects in Tamil Nadu. Offering 15/12 MPPTs, this series comes with a maximum 15A/20A DC input current per string, thus supporting bifacial 182mm/210mm modules.

Jaipur-based solar module manufacturer Insolation Energy Ltd has announced that its subsidiary, Insolation Green Energy, has incorporated four new wholly owned subsidiaries for the purpose of setting up solar power plants.

The inverter is designed for three-phase grid configurations without using external transformers. It contains gallium nitride technology, a first for Enphase’s microinverters.

DAS Solar has filed an environmental-impact assessment (EIA) for a 5 GW back-contact (BC) solar cell plant in Guizhou, China, expanding its existing manufacturing operations to supply large-scale and building-integrated PV (BIPV) installations.
