报告的PV系统标称值是在严格控制的测试条件下测量的。虽然严格标准化，以实现不同的，新制造的面板良好的基准能力;这些条件几乎不存在于现实生活中的实施网站。更糟糕的是，从长远来看，高度变化的气候，降水，烈日和冰冻的雪会磨损这些系统。因此，任何光伏系统的实际性能都不可避免地不同于标准测试条件下报告的性能。为了更准确地预测系统寿命期间的发电量，了解当地条件的影响以及光伏电池板对这些条件的适应性非常重要。为此，世界各地已经报道了几项户外性能研究，并且文献正在增长。这项工作报告的影响，福岛的天气，这是已知的，在秋季有风，在冬季有大雪，对安装的光伏系统。此外，属于不同光伏技术和制造商的许多面板并排安装，以比较其性能的变化，从而衡量其质量和弹性。为了调查微气候或当地地理条件的可能影响，利用了福岛县的两个试验场。最后，一个光伏系统的计算样本，以展示这些研究结果对光伏系统的规划和运行阶段的影响。
Nominal values reported for PV Systems are measured at carefully-controlled test conditions. While being strictly standardized to achieve a good benchmarking capability for different, newly manufactured panels; these conditions hardly exist in real-life implementation sites. To add to the problem, highly varying climate, precipitation, scorching sun and freezing snow wear out these systems in the long run. Therefore, actual performance of any PV system is, inevitably, different than those reported under standard test conditions. In order to have a more accurate expectation of power generation over the lifetime of a system, it is important to know the impact of local conditions and the resilience of PV panels to them. To this end, several outdoor performance studies have been reported around the world and the literature is growing. This work reports the impact of Fukushima's weather, which is known to be windy in autumn and have heavy snowfall in the winter, on the installed PV systems. Also, numerous panels belonging to different PV technologies and manufacturers are installed side-by-side to compare the variation in their performances and, thus, benchmark their quality and resilience. To investigate possible impact of micro-climate, or local geographical conditions, two test sites in Fukushima Prefecture are utilized. Finally, a sample PV system calculation is presented to showcase the impacts of these findings on a PV system in planning and operation stages.
