Reliability Analysis of Photovoltaic Module based on Measured Data

Abstract

Abstract This paper analyzes the reliability of photovoltaic modules based on the electrical data of photovoltaic modules collected by photovoltaic power stations. Traditional module life depends on equipment calibration and lacks consideration of the actual use of modules. The experimental data in this article comes from modules with different service hours in the real power plant environment. The extended β model with four free variables is used to model the power data of the modules to obtain the expected output power of the modules in each service time. The power generated by the module is used as a measure of the reliability of the module, and the reliability index is used to obtain indicators such as the failure rate and the average life of the module.
