In this paper, we would like to report on a prototype of dense array concentrator photovoltaic (DACPV) system including the practical implementation and economic assessment. The newly proposed system consists of primary concentrator in the form of non-imaging dish concentrator and secondary concentrator as an array of dielectric filled crossed compound parabolic concentrators coupled to multi-junction solar cells. Optical and electrical simulations have been carried out to analyze the overall performance of the prototype for difference rim angles and tracking accuracies. A special method has been developed to plot the I-V and P-V curves of the prototype on-site without using commercial I-V tracer. The average cell efficiencies for all basic modules in the DACPV receiver were measured onsite in the range from 35.0% to 36.1%, which is very close to the laboratory test result conducted by Spectrolab at 38.5%. On the other hand, the system efficiency of our prototype system was measured only in the range between 16.1% and 17.4% at DNI ranging from 740 to 801 W/m². For economic analysis, the cost per watt of current prototype has been determined as USD 5.8/W based on the price of only building one unit. The techno-economic of DACPV system can be further improved in the future by increasing solar concentrator ratio more than 1600 suns and reducing the optical losses incurred by the secondary concentrator.

在本文中，我们将报告密集阵列聚光光伏（DACPV）系统的原型，包括实际实施和经济评估。新提出的系统由非成像碟式聚光器形式的主聚光器和作为与多结太阳能电池耦合的电介质填充的交叉复合抛物线形聚光器阵列组成的次级聚光器组成。进行了光学和电气仿真，以分析原型在不同轮辋角度和跟踪精度方面的整体性能。已经开发出一种特殊的方法来现场绘制原型的IV和PV曲线，而无需使用商业IV示踪剂。现场测量的DACPV接收器中所有基本模块的平均电池效率在35.0％至36.1％的范围内，非常接近Spectrolab进行的实验室测试结果的38.5％。另一方面，在740至801 W / m ^2的DNI下，我们的原型系统的系统效率仅在16.1％至17.4％的范围内测量。为了进行经济分析，基于仅构建一个单元的价格，当前原型的每瓦成本确定为5.8美元/瓦。通过将太阳能聚光器的比率提高到1600太阳以上，并减少由二次聚光器引起的光损耗，将来可以进一步改善DACPV系统的技术经济性。
