分析了在韩国的第一个实际应用的设计和安装的建筑一体化光伏（BIPV）模块的窗户覆盖建筑物的正面，通过使用透明的薄膜非晶硅太阳能电池。通过2年的长期性能监测进行了该分析。通过对实际BIPV系统的2年监测，估算了单位功率输出的电能产生量，分别为48.4 kWh/kWp/月和580.5 kWh/kWp/年，而本研究中的实测发电量数据几乎是现有数据的一半，这些数据来自于一般的非晶薄膜太阳能电池应用。其原因是本研究中测试的BIPV系统的方位角向西南方向倾斜50度，并且由投影建筑物质量引起的自遮蔽导致发电效率进一步降低。从模拟影响因素，如方位角和阴影，在测试条件下，测量的能量产生效率可以提高高达47%，通过改变建筑物的位置方面的方位角和阴影，从而允许更好的太阳能辐射的光伏组件。因此，从BIPV系统的真实的应用来看，与方位角和遮蔽相关联的PV模块的安装可以说是对PV性能的本质影响因素，并且这两个因素都可以是有用的设计参数，以便优化用于建筑BIPV应用的PV系统。(C)2011爱思唯尔有限公司版权所有。
An analysis has been carried out on the first practical application in Korea of the design and installation of building integrated photovoltaic (BIPV) modules on the windows covering the front side of a building by using transparent thin-film amorphous silicon solar cells. This analysis was performed through long-term monitoring of performance for 2 years. Electrical energy generation per unit power output was estimated through the 2 year monitoring of an actual BIPV system, which were 48.4 kWh/kWp/month and 580.5 kWh/kWp/year, respectively, while the measured energy generation data in this study were almost half of that reported from the existing data which were derived by general amorphous thin-film solar cell application. The reason is that the azimuth of the tested BIPV system in this study was inclined to 50 degrees in the southwest and moreover, the self-shade caused by the projected building mass resulted in the further reduction of energy generation efficiency. From simulating influencing factors such as azimuth and shading, the measured energy generation efficiency in the tested condition can be improved up to 47% by changing the building location in terms of azimuth and shading, thus allowing better solar radiation for the PV module. Thus, from the real application of the BIPV system, the installation of a PV module associated with azimuth and shading can be said to be the essentially influencing factors on PV performance, and both factors can be useful design parameters in order to optimize a PV system for an architectural BIPV application.
