A 30 kW concentrator photovoltaic power plant was constructed and has started operation with the following new technologies: A new Concentrating PhotoVoltaic (CPV) tracker developed for high wind area like Korea and Japan by Daido Steel. (The power consumption of the tracking motors was only 19.6 W, namely 0.07% of the rated power.) With improved optics that reduce the mismatch losses associated with optical aberrations, an efficiency of 25.8% was achieved under standard testing conditions (STC) even in a large 23.8 m(2) array size. A rapid installation sequence was developed. It was designed for long-term power supply to a local sewage center. Peak power corresponds to 10% of the demand. As a result, the system performance ratio was 0.87, and the capacity factor was 11.7%. The energy generation per rated power was 1,020 kWh/kWp. While it is true that CPV systems perform better in dry and high irradiance areas, our 30 kW system installed in a cloudy area like Japan, showed satisfactory performance.
一座30千瓦的聚光光伏电站已建成并采用以下新技术开始运营：大同钢铁公司为韩国和日本等高风地区开发的新型聚光光伏（CPV）跟踪器。（跟踪电机的功耗仅为19.6瓦，即额定功率的0.07%。）通过改进光学器件以减少与光学像差相关的失配损失，即使在23.8平方米的大型阵列尺寸下，在标准测试条件（STC）下也实现了25.8%的效率。开发了快速安装顺序。它设计用于长期为当地污水处理中心供电。峰值功率相当于需求的10%。结果，系统性能比为0.87，容量因子为11.7%。每额定功率的发电量为1,020千瓦时/千瓦峰。虽然CPV系统在干燥和高辐照地区表现更好，但我们安装在日本等多云地区的30千瓦系统表现出令人满意的性能。
