小規模太陽光発電所の逸失電力量分析

～出力抑制と不適切な管理による累積損失率の比較～

Although the curtailment of solar energy in Japan remains at an appropriate level by international comparison, it is often considered serious because of the possibility that the amount of loss of energy due to curtailment may affect business operations. On the other hand, analysis of time-series data from more than 200 small-scale solar power plants compiled by the authors indicates that the amount of loss of energy due to improper maintenance is not negligible and has reached a level more serious than curtailment at some power plants. This report quantitatively evaluates the lost power generation from these two perspectives, proposing cumulative curtailment ratio as a novel indicator.
