As Above Vikram Solar Secures Major 289.87 MWp Order for Grid-Scale Solar in Rajasthan from NLC India Limited Kolkata, India, 27th October 2026: Vikram Solar, a leading Indian solar PV module manufacturer, has bagged an order to supply 289.87 MWp of N-TOPCon modules to NLC India Limited (NLCIL), on behalf of NLC India Renewables Limited (NIRL) for an 810 MW solar power project at the RUVN Solar Park in Pugal, Bikaner, Rajasthan, one of the largest solar parks in the country. NLC India Renewables Limited (NIRL) is a wholly owned subsidiary of NLC India Limited. Built on N-type TOPCon cell technology, the modules are designed to deliver higher energy yield and stable output in high-irradiance, high-temperature conditions such as those of western Rajasthan. Spread across the Thar region, the RUVN Solar Park is central to Rajasthan’s effort to harness its vast solar resource, as the state continues to lead India’s utility-scale solar build-out. A role in a project of this magnitude reinforces Vikram Solar’s standing as a trusted domestic supplier for grid-scale installations, where consistent quality, bankability and timely delivery are critical. The order further adds to the company’s order book as demand for high-efficiency, domestically manufactured modules continues to rise under India’s drive for self-reliance in solar manufacturing. Mr. Sameer Nagpal, Chief Executive Officer, Vikram Solar, said, “As India builds clean energy capacity at gigawatt scale, the industry is placing greater value on technology and supply partners it can rely on over the long term. Being entrusted with nearly 290 MWp of modules for this landmark project is a strong endorsement of our N-TOPCon technology and our ability to deliver at utility scale. As we deepen our integrated manufacturing capabilities, our priority is to give customers the performance certainty and supply reliability that projects of this size demand.” About Vikram Solar Limited: Vikram Solar Limited is one of the leading Indian solar module manufacturers, specializing in efficient photovoltaic (PV) module manufacturing, with an international presence across 39 countries.
