Kosol Energie Plans Lab To Test Long Durability Of Modules

Indian solar manufacturer Kosol Energie has now planned a dedicated lab to test the durability and reliability of solar modules. The top management of the firm told Saur Energy about their steps towards boosting research and development on solar modules.

Nitin Sangle, CEO of Sunray Solar, the solar vertical of Kosol Energie said the lab is likely to aid the fim in accessing the durability of the modules and ensuring long-lasting higher higher-efficiency solar modules. He brought attention to its NABL-accredited reliability laboratory, capable of simulating 30 years of solar module performance within just seven months — a move the company says underscores its commitment to long-term performance and product integrity.

Solar Module Reliability Lab 

“This lab is not just a facility, it’s our assurance that what we ship today will still perform efficiently decades from now,” Sangle told Saur Energy. “Such long-cycle tests help determine whether a module can actually last 30 years or not — something the industry needs to be more transparent about.”

The reliability lab complements Kosol’s investments in module engineering and quality control, which, according to Sangle, have helped refine its latest product — the 620Wp Sun Series TOPCon module. Built within the frame of a conventional 550Wp panel, the new product offers increased generation, reduced space requirements by about 15%, and improved levelised cost of energy (LCOE) for solar project developers.

“We believe this will help solar developers extract more value from each project,” Sangle said. “We hope to see wider adoption of our advanced modules.”

Current capacity 

Kosol Energie currently manufactures around 3.1 GW of solar modules annually and offers a broad portfolio spanning solar streetlights, water pumps, cookers, dryers, and rooftop and utility-scale PV systems, tailored for residential, C&I, and utility customers. The company undertakes projects ranging from 1 kW to several megawatts.

While P-type mono PERC remains the company’s baseline technology, its n-type TOPCon modules have seen significant R&D investment. “N-type is a newer technology with tremendous potential, but not all manufacturers have approached it responsibly,” Sangle said. “Our version ensures high efficiency with lower degradation.”

Solar Cell Production

Kosol has not yet entered the solar cell manufacturing space but is focused on module performance. “We use A-grade solar cells and conduct six EL (electroluminescence) scans per panel — three times the industry norm — to ensure top-tier quality,” he added.

The company also maintains a strong presence in the U.S. market, supplying modules and handling EPC (engineering, procurement and construction) projects. Expansion plans in America are under consideration, Sangle said.
