28th February 2025: A team from the National Institute of Technology (NIT) Rourkela, led by Associate Professor Susovon Samanta, has developed a new method to enhance solar power systems’ efficiency, affordability, and reliability. The team, including PhD student Satabdi Bhattacharya and dual-degree student Madhusmita Barik, has created a voltage sensor-based Maximum Power Point Tracking (MPPT) technique that simplifies and reduces the cost of solar power systems.
Their method eliminates the need for current sensors, using a voltage sensor or resistor divider circuit to improve tracking accuracy and maintain peak efficiency, even under varying weather conditions. Supported by the Department of Science and Technology (DST) under the Clean Energy Research Initiative (CERI), the team’s innovation has been granted a patent (Patent No. 543360).
This technology has significant potential for use in solar-powered IoT devices, consumer solar products, and microgrid solutions, especially in remote areas. The research has been published in respected journals such as IEEE Transactions on Sustainable Energy and IEEE Transactions on Industrial Electronics.
