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.

评估热电发电机与太阳能光伏板集成的性能和可行性：一个案例研究

本案例研究探讨了热电发电机（TEG）与太阳能光伏（SPV）面板的集成，旨在降低面板温度，提高能量密度，减少空间要求。对理想PV、PV + TEG和单独PV进行了对比实验分析。在PV + TEG模式下，分析了所有情况下180个TEG的445Wp SPV面板。实验结果表明，在相同的功率输出下，PV + TEG混合系统的功率密度提高了8.5%，空间需求减少了16%。然而，与单独的光伏板相比，集成的单位成本增加了25.12%，使其在经济上不太可行。理想的光伏板表现出优越的成本效率和功率密度。尽管操作成本较高，但由于能量密度较高，混合系统在空间受限的情况下是有益的。此外，从技术经济分析中得出结论，重点优化SPV下的teg数量和改进MPPT算法，以提高性能和降低成本。

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.
