RenewSys Signs 1.1 GW POE Encapsulant Supply Pact with Kosol Energie RenewSys India and Kosol Energie, headquartered in Mumbai and Ahmed- abad, respectively, have signed a 1.1 GW supply agreement for high-perfor- mance POE (polyolefin elastomer) en - capsulants. The ten-month deal, running from December 2025 to September 2026, will support Kosol’s production of ad- vanced, high-efficiency solar modules at its state-of-the-art manufacturing facilities. The signing was attended by senior leaders from both companies: Manan Jhala, Rakesh Singh, Avinash Hiranan- dani, Kalpesh Kalthia, Kayan Kalthia, and Mitesh Parikh. “Our 1.1 GW agreement with Kosol Energie reaffirms RenewSys’s lead - ership in providing high-quality, In- dia-made encapsulants that meet global performance standards,” said Avinash Hiranandani, Managing Director, Re- newSys India. “We are proud to support India’s tran- sition to clean energy through a reliable and sustainable solar component supply chain,” added Hiranandani. Kalpesh Kalthia, Managing Director of Kosol Energie, added, “This part- nership ensures Kosol continues to deliver solar products built with the highest-grade components. RenewSys’s proven POE technology aligns with our focus on quality, reliability, and long- term performance as we meet growing demand in India and beyond.” The agreement reinforces RenewSys’s position as a trusted supplier to major module makers and advances its mission to power global clean-energy growth. ENERGY UPDATES Govt Notifies New Minimum Efficiency Standards for Solar Inverters, Effective January 2026 The Ministry of Power has specified minimum overall efficiency standards for grid-connected solar inverters up to 100 kW capacity being manufactured in or imported to India. The norms, issued in consultation with the Bureau of En- ergy Efficiency (BEE), will remain valid from January 1, 2026 to December 31, 2027. Under the new framework, all sin- gle-phase (230 V AC, 50 Hz) and three- phase (up to 415 V AC, 50 Hz) non-stor - age, grid-connected solar inverters must meet prescribed minimum overall effi - ciency thresholds based on their rated output power. The standards draw upon IS 17980:2022 and IEC 62891:2020 test protocols. The minimum overall efficiency require - ments are set at 92 percent for inverters below 1 kW, 93 percent for inverters be- tween 1 kW-3 kW, 95 percent for those between 3 kW-5 kW, 96 percent for the 5 kW-10 kW range, 97 percent for invert- ers between 10 kW-20 kW, and 98 per- cent for inverters above 20 kW. Further, there shall be no negative tolerance in the minimum overall efficiency require - ment criteria for obtaining the BEE en- dorsement label. Every tested product must meet or exceed the mandated thresholds, in- cluding manufacturing variations. The government has also made adherence to BIS compliance and testing under the latest IS 17980:2022 standard mandato- ry for participation in the BEE labelling programme. The Power Ministry notification forma - lises the requirement for manufacturers to display an endorsement label reflect - ing inverter efficiency categories, based on static MPPT efficiency and steady- state conversion efficiency. Accredit - ed laboratories under NABL, ILAC, APLAC or NISE will be authorised to issue test reports. The move is expected to bring greater transparency and quality assurance to the solar equipment market, improve system yields, and enhance consumer confidence at a time when India’s solar adoption continues to accelerate across residential, commercial, and utility sec- tors. energetica INDIA- November_2025 14
