84. Development of a hazard estimation method of photovoltaics based on long-term trend of generation and solar radiation data

Abstract

As monthly generations of solar power plants vary according to their environment, especially to solar radiation and temperature on the backside of the PV panels, it is difficult to quantitively grasp a long-term decline trend of generation and to estimate the main hazard only by monitoring a time series of the generation data．This paper reports a development of a hazard estimation method of photovoltaics, especially for small-scale plants, based on long-term trend of generation and solar radiation data.
