Abstract

The continuous rise in energy demand and growing environmental concerns necessitate innovative approaches to optimizing renewable energy technologies. Among these, photovoltaic (PV) panels play a pivotal role but suffer efficiency losses due to surface overheating. Ground-coupled heat exchangers (GHEs) have emerged as a promising solution, leveraging geothermal energy to regulate PV panel temperatures.

This review explores the application of GHEs for PV cooling, focusing on technical advancements, operational parameters, and soil-related influences. Key aspects analyzed include GHE design, working fluid characteristics, mass flow rates, and pipe material properties, all of which critically impact cooling efficiency and energy output. Recent studies indicate that GHE systems can reduce surface temperatures by 20 °C–25 °C and enhance thermal and electrical efficiency by 20 %, respectively. Design innovations, such as vertical and spiral configurations and nanofluid-enhanced working fluids, demonstrate significant performance improvements.

However, several challenges persist, including installation complexities, maintenance difficulties, and soil-dependent variability. This review also examines the economic and environmental feasibility of GHEs, emphasizing their integration with renewable energy systems for sustainable development. Future research directions include optimizing GHE designs, employing artificial intelligence for performance prediction, and exploring cost-effective materials and configurations.

By addressing current limitations, GHEs can significantly enhance PV efficiency, reduce carbon footprints, and promote the broader adoption of renewable energy technologies. This comprehensive review aims to guide researchers and practitioners toward the innovative deployment of GHEs in solar energy applications.
