KOSOL Energie has signed a formal agreement with the Andhra Pradesh Government for the deployment of distributed rooftop solar projects, covering 1.5 lakh homes across the state, as part of the PM Suryaghar Yojana. These microinverters will be deployed there, the company said.
Commenting on the development, Kalpesh Kalthia, Chairman and Managing Director, KOSOL Energie, said, “This 360 MW microinverter deal is a defining milestone not just for KOSOL Energie, but for India’s solar journey. By adopting advanced microinverter technology at this scale, we are reinforcing our commitment to safety, efficiency, and long-term performance. Our partnership with Hoymiles reflects our shared vision of accelerating India’s transition to a cleaner, smarter, and more resilient energy future.”
Piyush Sharma, Channel Business Director, Hoymiles India, remarked, “This 360 MW agreement with KOSOL Energie represents a defining moment for microinverter adoption in India. As the country’s largest microinverter deal to date, it will play a crucial role in accelerating high-quality rooftop solar deployment nationwide. KOSOL Energie’s trust in our technology reflects the industry’s growing confidence in microinverter-based systems for large-scale applications.”
This partnership builds on Hoymiles’ growing presence in India, including successful installations such as a 100 kW solar project in Guruvayur, Thrissur, Kerala. Through this collaboration, KOSOL Energie aims to leverage globally proven microinverter technology, cost-optimised system architecture, along with strong local and global after-sales support, including 24/7 technical assistance and rapid resolution timelines, the company stated.
