The company said the upgraded facility is designed to conduct accelerated lifetime testing, support research and development of new module technologies, and validate product durability under India's diverse climatic conditions.
The laboratory is equipped to perform 18 module qualification tests covering mechanical, thermal, environmental, electrical and corrosion-related parameters, aligned with international standards including IEC, UL and BIS requirements.
According to the company, the facility will allow it to independently validate the performance and durability of its solar modules before deployment, reducing reliance on external testing cycles and accelerating product development.
The testing capabilities include thermal cycling, damp heat exposure, humidity freeze testing, potential-induced degradation (PID) resistance, UV exposure, hail impact resistance, mechanical load testing, salt mist corrosion and sand and dust testing, among others.
The company said the facility also incorporates an AI-assisted electroluminescence testing system to detect micro-cracks and manufacturing defects during production.
Located alongside Gautam Solar's manufacturing plant in Bhiwani, the laboratory is now fully operational with all 18 testing stations commissioned and validated.
The expansion comes as India's solar manufacturing industry seeks to improve product quality and reliability standards amid growing domestic demand and rising exports to international markets.
Gautam Solar said the facility would strengthen confidence among project developers, engineering, procurement and construction (EPC) contractors, financial institutions and international buyers that increasingly require robust in-house testing capabilities in addition to third-party certifications.
The company noted that the laboratory complements its existing certifications, including IEC, UL, CE, CEC and ALMM approvals, and supports its ambitions in export markets such as Europe, the United States and Southeast Asia.
"At Gautam Solar, quality is not a claim — it is a system. The Upgrade of our Reliability Lab takes that commitment to a fundamentally new level. We can now conduct the full suite of accelerated lifetime tests in-house, at our own facility, with our own engineering team. That means we catch problems before they reach the field, accelerate new product development with confidence, and give every customer, lender, and partner detailed, internally verified reliability data alongside our third-party certifications,” said Gautam Mohanka, Director, Gautam Solar.
“It signifies our 29+ years of experience, excellence and trust. India is building the world’s largest solar programme. This lab is our commitment to ensuring every Gautam Solar module is worthy of that responsibility," added Mohanka.
