India-based Involtics has launched its GTSI series of single-phase hybrid inverters in 3 kW, 3.6 kW, 5 kW and 6 kW sizes for residential solar systems.
ACME Solar signs 450 MW PPA in India, commissions new 38 MW/82 MWh BESS
ACME Solar has signed two power purchase agreements (PPAs) totaling 450 MW under a firm, dispatchable renewable energy (FDRE) project with SJVN Ltd. It also commissioned an additional 38 MW/82 MWh at its Jaisalmer battery energy storage system (BESS) facility in Rajasthan.
Group Surya commissions 500 MW G12R module line in India
Group Surya has launched a 500 MW G12R solar module production line in Odisha, India, with plans to double capacity to 1 GW within months.
Indian renewables gain 8.6 GW of relief after court delays on bird protections
India Ratings and Research said India’s Ministry of New and Renewable Energy (MNRE) will treat commissioning delays linked to Supreme Court proceedings over the Great Indian Bustard as a force majeure-like event, easing liquidated-damages risk for about 8.6 GW of renewable projects.
RENA secures 1.2 GW TOPCon equipment order in India
RENA Technologies says it will supply advanced wet chemical processing systems for Celloraa Energy’s 1.2 GW tunnel-oxidized passivated contact (TOPCon) solar cell line in Gujarat, India, with water consumption cut by 50%, H₂O₂-free processes, and start of cell production targeted for the end of fiscal 2026–27.
Indian researchers build transparent perovskite-silicon tandem solar cell with 30.2% efficiency
The transparent four-terminal perovskite solar cell employs an ion-modulated spiro-MeOTAD hole transport layer, which passivates interfacial defects, enhances carrier dynamics, and allows for a tunable work function in wide-bandgap perovskites. When integrated into mechanically stacked 4T tandems with an n-TOPCon cell, the device achieved an overall efficiency of 28.4–30.2%, along with improved open-circuit voltage and fill factor.
Premier Energies unveils India’s first zero-busbar TOPCon solar cell
Premier Energies Ltd today unveiled India’s first zero-busbar (0BB) TOPCon solar cell at Intersolar India. The 0BB design marks a structural shift from traditional 10BB and 16BB architectures, replacing thick silver busbars with a dense matrix of ultra-fine silver lines to collect current.
India expected to install about 42.5 GW of new solar capacity in 2026
India installed around 37.8 GW of solar capacity in 2025, according to JKM Research. This comprised about 28.6 GW of new utility-scale solar, a 54.6% increase from 2024, and 7.9 GW of rooftop solar, up 72% year on year. Off-grid additions stood at 1.35 GW, compared to 1.48 GW in 2024.
