Abstract
It has been passing through 10 years after the introduction of the “Surplus power purchase system for solar power (photovoltaic power generation)”. So-called 2019 year’s problem suggests us a turning point of our attitude facing to the solar power. In this paper, we pick up the light and shadow phases of the solar power system based on a record of 10 years’ photovoltaic generation in our personal small power plant. With the analysis of the record, we discuss mainly on the topics of (1) relationship between characteristics of the climate of particular region and calendar, and (2) problems of solar power system and their countermeasures. Finally, we summarize our results from the relevance to the time studies.
