Kosol Energie is preparing to expand into battery energy storage systems and agricultural solar as its next growth engines, backed by a strong order pipeline and technology partnerships. Executive director Kayan Kalthia said the company has spent 15 years building a presence in the solar PV sector with a focus on quality and reliability amid intense price competition. The firm is prioritising quality over scale to retain customers and enter new markets.

The company earlier took projects with strict generation guarantees to build credibility and was part of an early rooftop tender, executing a two point five Megawatt (MW) project with SunEdison. More recently it received a letter of intent for 300 MW of rooftop installations under a broader one point one Gigawatt (GW) programme, making it the largest order winner and reflecting growing execution capability. The order book spans multiple verticals and supports further investment.

Kosol is expanding into BESS through a technical partnership with US-based Gridscale to bring battery software and system expertise to India. The company is focusing on increasing domestic value addition in components such as battery management systems and energy management systems to control performance and safety. It has also launched an AI driven microgrid planning platform that models energy use and recommends storage sizing and returns for developers and businesses.

The agricultural division has installed more than 10,000 solar pumps across seven Indian states and over 200 districts, and the agriculture brand Koraam has become the company's most profitable vertical with solar based cold storage and other farmer-centric solutions. The firm reported an order book of more than Rs 40 billion (bn) across business segments and expects battery storage to attract many new entrants followed by consolidation as quality and reliability emerge as decisive factors. The executive said policy support should increasingly target research and skill development alongside financial incentives to capitalise on domestic strengths and reduce sectoral risk.
