Abstract

This case study explores the integration of thermoelectric generators (TEG) with solar photovoltaic (SPV) panels, aiming to reduce panel temperature, improve energy density, and decrease space requirements. A comparative experimental analysis between ideal PV, PV + TEG, and PV alone is conducted. A 445Wp SPV panel for all cases with 180 TEGs attached in PV + TEG mode is analyzed. Experimental results show that the hybrid PV + TEG system enhances power density by 8.5 % and reduces space needs by 16 % for the same power output. However, the integration increases the cost per unit by 25.12 % compared to PV panels alone, making it less economically feasible. Ideal PV panels demonstrated superior cost efficiency and power density. Despite the higher operational costs, the hybrid system is beneficial in space-constrained scenarios due to its higher energy density. Further, a conclusion is drawn from the techno-economic analysis to focus on optimizing the number of TEGs placed under SPV and improving MPPT algorithms to enhance performance and reduce costs.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
