本文介绍了基于效率方程的模型的发展,以评估HCPV/T系统的性能,并将其输出与安装在意大利巴勒莫的操作案例研究系统的数据进行了比较。用实际运行系统的数据验证了模型的有效性。该模型可以评估(a) InGaP/InGaAs/Ge TJ太阳能电池的电效率和(b)一个模块的电和热功率/能量生产潜力。通过得到实验结果与分析结果的线性回归图,将模型预测结果与实验电、热数据进行比较;实验电学和热学结果的ther2分别为0.91和0.87。利用该模型,评估的InGaP/InGaAs/Ge TJ太阳能电池的平均日分析效率和实验效率分别为33%和25%;每日最大实验值为30%。根据实验数据推导出的方程可知,一个模块产生的年解析电能和势能分别为158 kWh/m2/年和144 kWh/m2/年,年解析热能和势能分别为375 kWh/m2/年和390 kWh/m2/年。
This paper presents the development of a model based on efficiency equations to evaluate the performance of an HCPV/T system and compares its outputs with data of an operational case-study system installed in Palermo, Italy. The model is validated with data of the operational system to show real performance. The model can evaluate (a) the electric efficiency of the InGaP/InGaAs/Ge TJ solar cell and (b) electrical and thermal power/energy production potential of one module. The model predictions are compared with experimental electric and thermal data by obtaining linear regression plots of experimental results vs. analytical results; theR2for experimental electrical and thermal results are 0.91 and 0.87 respectively. Using the model, the evaluated average daily analytical and experimental InGaP/InGaAs/Ge TJ solar cell efficiencies are 33 % and 25 % respectively; with a maximum daily experimental value of 30 %. It was found that the annual analytical and potential (based on derived equations from experimental data) electric energy produced by one module are 158 kWh/m2/year and 144 kWh/m2/year respectively, while the annual analytical and potential thermal energy are 375 kWh/m2/year and 390 kWh/m2/year respectively.
