摘要

本文对日本雪国建筑墙体上安装的12kwp光伏阵列的性能进行了总结和分析。该分析是基于1999年以来2年的监测结果。该光伏系统的亮点在于，通过光伏阵列周围新雪反射的阳光，增加了直流能量输出。分析结果表明，降雪天气的日综合直流能量输出远高于无降雪天气。分析结果还表明，积雪反射不仅会影响光伏发电系统的输出功率，还会影响逆变器的额定功率。

Performance analysis of a PV array installed on building walls in a snowy country

This paper summarizes the performance and analysis of a 12 kWp PV array installed on building walls in a snowy country in Japan. The analysis is based on the monitoring results over 2 years since 1999. The highlight of this PV system is that the DC energy output increased by reflection of sunlight from fresh snow around the PV array. Analyzed results show daily integrated DC energy outputs on snowy days are much higher than those without snowfall. The analyzed results also show the reflection from snow affects not only the power output, but also a power rating of inverter for the building-wall PV system.
