NIT Rourkela Secures Patent for Low-Cost Solar Power Optimization Technology

A research team from the National Institute of Technology (NIT) Rourkela has developed an innovative and cost-effective solution to maximize solar power generation under varying weather conditions. Led by Prof. Susovon Samanta from the Department of Electrical Engineering, along with researchers Satabdi Bhattacharya and Madhusmita Barik, the team has secured a patent for their breakthrough technology, titled “Method And System For Voltage Sensor-based Maximum Power Point Tracking For Photovoltaic System.”

Supported by the Department of Science and Technology (DST) under the Clean Energy Research Initiative (CERI), the patented technology enhances Maximum Power Point Tracking (MPPT), a crucial mechanism in solar energy systems. Unlike traditional MPPT methods that rely on expensive current sensors and slow response times, this innovation employs a voltage sensor-based approach, significantly reducing costs and improving tracking efficiency.

The system comprises a solar panel, voltage sensor circuit, DC-DC converter, and a microcontroller, ensuring quick adaptation to fluctuations in sunlight and temperature without artificial perturbations during steady-state conditions. This enables more stable and efficient power extraction, making solar energy systems more affordable and reliable.

Speaking about the innovation, Prof. Samanta highlighted its broad applications, including IoT devices, home solar setups, and off-grid energy solutions in remote areas. By eliminating costly components and improving performance, the technology paves the way for accessible and efficient renewable energy solutions, reinforcing NIT Rourkela’s commitment to clean energy advancements.
