JAMMU, Apr 21: A day before of World Earth Day, Shoolini University’s (SU) Centre of Excellence in Energy Science and Technology today unveiled a novel Thermo Electric Cooling (TEC) system for Photovoltaic (PV) modules used in solar panels.
This innovative method addresses the critical issue of solar panel overheating, significantly enhancing power generation and extending panel lifespan.
Led by researchers Dr Rahul Chandel and Dr Shyam Singh Chandel, the Photovoltaics Research Group at Shoolini University has demonstrated that TEC systems can precisely control panel temperatures by converting excess thermal energy into electricity, avoiding the limitations of traditional air- or water-cooling techniques.
In their experimental study conducted in Shimla, a TEC-equipped solar panel maintained a stable temperature around 25°C, compared to a standard panel which soared to 63°C, an impressive difference of up to 38°C.
This cooling innovation led to efficiency improvements in the range of 6-27%, depending on PV technology and installation type.
Highlighting the global importance of this research, Prof Atul Khosla, Vice Chancellor of SU, said, “At Shoolini University, we are committed to driving transformative innovations that make a real-world impact. The breakthrough by Dr Rahul Chandel and Dr Shyam Singh Chandel represents a major step forward in sustainable solar technology and has been recognized by prestigious platforms like PV Magazine. This work has the potential to change how the world produces and utilizes solar energy.”
Speaking on the occasion, Dr Rahul Chandel emphasized the need for further innovation, particularly in developing high-efficiency thermoelectric materials through advanced nanofabrication techniques, to bring TEC cooling fully into commercial viability.
In addition to improving energy output, the TEC technology promises significant long-term operational and economic benefits. By reducing thermal stress, it extends the service life of solar panels, lowers replacement costs and minimizes solar waste.
While TEC systems can be retrofitted onto existing PV modules, their greatest impact is expected in new integrated designs optimized for diverse climates, from tropical zones to arid deserts.
Currently, the research team is seeking collaborations with industry partners and funding agencies to scale and commercialize the technology.
