ผลของรูปแบบการไหลแบบธรรมชาติกับการไหลแบบบังคับของน้ำต่อค่าประสิทธิภาพของแผงผลิตไฟฟ้าและความร้อนร่วมชนิดกึ่งโปร่งแสง.

The semi-transparent photovoltaic thermal module (SPVT) is a solar module that can generats electricity, heat and part of sun light through the module while operating, which is beneficial for improving of solar utilization per area of the module. This paper presents the effects of the natural and force flow patterns on the efficiency of the SPVT module. The 100 W SPVT module had an area of 0.72 m2 and was designed, studied and experimented at Mahasarakham University. The solar module temperature, water temperature, ambient temperature, solar irradiation and electrical parameters were measured every 15 minutes. The analysis of results showes that the water with active flow pattern induces a module temperature lower than in the passive flow pattern. The active flow of water at 0.02 kg/s causes maximum electrical efficiency, thermal efficiency and overall efficiency of SPVT module by 12.37%, 49.36% and 62.09% respectively. Moreover, thedSPVT module provides sufficient illuminance for the general area during the day. [ABSTRACT FROM AUTHOR]
