Abstract

The advancement of PVT technology in the contemporary era is experiencing an upward trend. This phenomenon can be attributed to the growing societal demand for energy, particularly renewable energy derived from solar sources. The present study investigates the rectangular configuration of a water-based heat absorber within a photovoltaic-thermal (PVT) system. The rectangular model PVT system was simulated using nine different mass flow rate of water variations within the rectangular model channel. The dataset has nine mass flow rate of water variants ranging from 0.001 kg/s to 0.009 kg/s, as well as six solar radiation variations: 500 W/m2, 600 W/m2, 700 W/m2, 800 W/m2, 900 W/m2, and 1000 W/m2. The maximum average outlet temperature achieved under 1000 W/m2 solar radiation is 50.53%, given a 0.001 kg/s fluid mass flow rate. The maximum average photovoltaic (PV) efficiency is 11.93% when exposed to 500 W/m2 solar radiation intensity. The maximum average photovoltaic-thermal (PVT) efficiency is 76.23% when exposed to 500 W/m2 solar radiation intensity. Therefore, utilizing rectangular collectors in water-based photovoltaic-thermal systems potentially substantially enhanced the average thermal efficiency and overall PVT efficiency. Consequently, it is advisable to consider incorporating rectangular collectors in the future improvements of PVT technology.

基于矩形集热器的光电热模拟方法

当代光伏发电技术的发展呈上升趋势。这一现象可归因于社会对能源，尤其是来自太阳能的可再生能源日益增长的需求。本研究调查了光伏热发电（PVT）系统中水基吸热器的矩形配置。利用矩形模型通道内九种不同质量流量的水变化对矩形模型 PVT 系统进行了模拟。数据集包含九种水的质量流量变化，从 0.001 kg/s 到 0.009 kg/s，以及六种太阳辐射变化：500 W/m2、600 W/m2、700 W/m2、800 W/m2、900 W/m2 和 1000 W/m2。在 0.001 kg/s 的流体质量流量条件下，1000 W/m2 太阳辐射条件下的最大平均出口温度为 50.53%。在 500 W/m2 太阳辐射强度下，最大平均光电（PV）效率为 11.93%。当太阳辐射强度为 500 W/m2 时，最大平均光电热（PVT）效率为 76.23%。因此，在水基光电热系统中使用矩形集热器可大幅提高平均热效率和整体光电热效率。因此，在未来改进光伏热技术时，最好考虑采用矩形集热器。
