Kirloskar Brothers Limited (KBL) has been granted Indian Patent No. 569497 for its innovative “Hotspot Mitigation Circuit for Photovoltaic Module,” marking a major stride in solar technology. The patent, valid for 20 years from December 20, 2018, addresses a persistent issue in solar energy systems—hotspot formation caused by partial shading.
Hotspots occur when shaded cells in a photovoltaic (PV) module experience reverse bias, leading to overheating, cell damage, and potential fire hazards. KBL’s circuit significantly reduces reverse bias voltage across these cells, preventing breakdown and enhancing overall module reliability.
This invention not only improves safety but also extends the lifespan of solar panels, making them more dependable for long-term energy generation. The technology is especially relevant as India accelerates its renewable energy mission.
Chairman and Managing Director Mr. Sanjay Kirloskar emphasized the company’s commitment to sustainable innovation, stating that the patent reflects KBL’s dedication to engineering excellence and its role in advancing clean energy solutions.
With this breakthrough, KBL reinforces its position as a leader in indigenous technology development, aligning with global sustainability goals and the evolving demands of the energy sector.
