82. Formulation of Output Change over Time of Photovoltaic Modules

Abstract

Formulas of output change of photovoltaic modules for long term are not yet generally recognized, so that problems remain. In this study, the basic equation for output change over time of photovoltaic modules is derived. Data with complicated changes was able to be expressed by multiplying two basic equations. Parameters can be exchanged to ones at arbitrary temperature by Arrhenius plot. It could be confirmed to apply data to the basic equation in other tests.
