Abstract

This research focuses on developing a method of evaluation the effect of concentrator on the solar panel performance to get a higher power and optimum efficiency. Also the effect of temperature on the solar panel system with and without concentrator was studied. A Flat Mirror has been used as a Concentrator (FMC) for low cost and low control power consumption which was fixed to the solar panel module. FMC has been used to increase the incident irradiance on solar panel system by concentrating the sun light ray on it and then to improve the cell performance. A comparison is made between two PV solar panel systems with and without concentrator. The FMC consists of two flat mirrors made of glass, with dimensions (146cm × 68cm) enclosed by aluminum frame and connected at an angle 60 ° with a solar panel (147cm × 68cm) tilted at 45° from the horizon. The results indicated that when the concentrator is used with the solar panel the efficiency increased by a factor of (51%) to (64%) and the variation in efficiency (Δƞ) is (25.4%), the variation in maximum output power (ΔPm) is (17%) and all solar parameters increased. The temperature of the environment affected all solar panel characteristics especially the power, and efficiency affected strongly by high temperature.This research focuses on developing a method of evaluation the effect of concentrator on the solar panel performance to get a higher power and optimum efficiency.

利用平镜聚光器提高太阳能电池板的性能效率

本研究的重点是开发一种评估聚光器对太阳能电池板性能影响的方法，以获得更高的功率和最佳的效率。同时研究了温度对太阳能电池板系统的影响，包括带聚光器和不带聚光器。利用平板反射镜作为聚光器(FMC)，将其固定在太阳能电池板模块上，具有低成本和低控制功耗的特点。FMC通过将太阳光集中在太阳能电池板上，从而提高太阳能电池板系统的入射辐照度，从而提高电池的性能。对两种带聚光器和不带聚光器的光伏太阳能电池板系统进行了比较。FMC由两个由玻璃制成的平面镜子组成，尺寸(146cm × 68cm)由铝框架包围，与太阳能电池板(147cm × 68cm)以60°的角度连接，从地平线倾斜45°。结果表明:当聚光器与太阳能板配合使用时，效率提高了51% ~ 64%，效率变化(Δƞ)为25.4%，最大输出功率变化(ΔPm)为17%，各项参数均有所提高。环境温度对太阳能板的各项特性影响最大，其中功率影响最大，而效率受高温影响较大。本研究的重点是开发一种评估聚光器对太阳能电池板性能影响的方法，以获得更高的功率和最佳的效率。同时研究了温度对太阳能电池板系统的影响，包括带聚光器和不带聚光器。利用平板反射镜作为聚光器(FMC)，将其固定在太阳能电池板模块上，具有低成本和低控制功耗的特点。FMC通过将太阳光集中在太阳能电池板上，从而提高太阳能电池板系统的入射辐照度，从而提高电池的性能。对两种带聚光器和不带聚光器的光伏太阳能电池板系统进行了比较。FMC由两个由玻璃制成的平面镜子组成，尺寸(146cm × 68cm)由铝框架包围，与太阳能电池板(147cm × 68cm)以60°的角度连接，从地平线倾斜45°。结果表明，当聚光器与太阳能板配合使用时，效率提高了1倍(51%)至1倍(64%)，效率变化幅度较小。
