Shoolini University Unveils Breakthrough Thermoelectric Cooling System to Boost Solar Panel Efficiency and Lifespan

•  A new thermoelectric cooling (TEC) technology enhances solar panel efficiency by up to 27%, effectively solving overheating issues without using harmful refrigerants.
•  The breakthrough extends panel lifespan, reduces energy waste, and supports global clean energy and climate action goals (SDG 7 and SDG 13).

Shoolini University’s Centre of Excellence in Energy Science and Technology before World
Earth Day on April 22 has announced a pioneering advancement in solar energy technology with the
development of a novel thermoelectric cooling (TEC) system for photovoltaic (PV) modules. 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.
A major highlight of this technology is its environmental impact: unlike conventional cooling systems
that rely on harmful chlorofluorocarbons (CFCs), TECs provide an eco-friendly alternative with zero
greenhouse gas emissions. As global electricity demand for space cooling is expected to triple by
2050, especially in developing nations, traditional systems pose a growing environmental challenge.
TEC technology addresses this by eliminating the need for refrigerants, offering a sustainable
solution to the increasing demand for energy-efficient cooling while mitigating climate change. This
makes TEC an essential innovation in balancing global energy needs with environmental
responsibility, supporting clean energy initiatives (SDG 7) and climate action goals (SDG 13).
Highlighting the global importance of this research, Prof. Atul Khosla, Vice Chancellor of Shoolini
University, 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.”
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. 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.
As the global demand for clean energy rises and extreme climates challenge existing solar
technologies, Shoolini University’s innovation offers a promising path toward a more resilient,
efficient, and sustainable energy future.
