UAH research aims to improve solar panel performance thru geothermal cooling

• By utilizing geothermal cooling, a research group from the University of Alcala in Spain has actually established a prototype solar panel with approximately 14% greater performance.

A research group from the University of Alcala (UAH) in Spain has actually created a prototype photovoltaic panel with integrated geothermal cooling, connected to a superficial borehole. With this prototype, the research group has observed effectiveness renovations of as much as 14%-- a considerable step for the photovoltaic or pv solar power technology. The term paper can be accessed here.

Ignacio Valiente develop the Mechanical, Electrical, and also Thermal Technologies Research Group is leading the research team working with the project "Sustainable renovation of power efficiency of solar panels via a modular geothermal cooling system." The project was financed by the community of Madrid after the 2019 require young researchers. The research was also identified as the very best entrance throughout the 2022 Conference on Renewable Energy as well as Environment Engineering.

The research team focused on photovoltaic solar power as it was the cheapest source of renewable energy. Despite the affordable, the reduced efficiency of solar panels stays a significant limitation. Based upon the energy gotten by photovoltaic panels and also their outcome electrical energy, the effectiveness commonly does not go beyond 20%, with much of the waste energy converted to heat.

By acknowledging that the subsurface has a stable temperature level of around 15 degrees Celsius, the research team suggested a cooling system for the panels connected to a superficial geothermal tank. A prototype was then constructed with a solar panel that had actually an integrated heat exchanger at the rear. This was then attached to one more heat exchanger situated 15 meters underground. A tiny pump circulates the cooling fluid through the system.

With the system, the team has actually observed photovoltaic panel temperature level decreases of as much as 20 levels Celsius and also net system performance improvements of as much as 14%. As the heat from the panels is minimal, the temperature of the subsurface tank remains relatively continuous.

The prototype solar panels are not mounted at the Polytechnic School of the University of Alcala where their efficiency is being contrasted to standard panels. The research team has additionally received interest from companies for the modern technology yet the team states that more research requires to be done before to lower the modern technology's production, operation, as well as maintenance costs.
