| Abstract |
Serpentine PV/T (Photovoltaic/Thermal) hybrid solar collector is a co-generation system that produces electricity and heat using one collector. In this study, we analyzed the thermal-electrical performance by theoretical analysis and experiment. The serpentine absorber whose solar circuit comprises one whole pipe without connection, is simpler in its composition than the header-riser absorber and also has low flow rate, making it possible to improve thermal stratification in the water tanks. Especially when the absorber is laminated with solar cell through a thin adhesive layer of ethylene-vinyl acetate (EVA), the thermal resistance is minimized and the manufacturing process can be automatized. Zhang and Lavan’s analytical model was introduced to determine the heat removal factor of serpentine absorber, and iterative method was used to obtain these solutions linked to the solar cell power generation analysis. To verify the validity of the theoretical analysis, the thermal performance of PV/T collector was tested in accordance with KS standards (KS B 8295). As a result, the numerical results agreed well with the experimental data. |
