Abstract

It is becoming more important to evaluate the installed PV system´s performance and loss factors to enhance the system´s efficiency and pull more electric power from the systems. This paper describes the evaluation method of PV systems and summarizes the results of annual performance and loss analysis. Grid voltage and snow coverage are two major serious loss factors for PV systems, optimized array configuration results in more system yield on roof mounted residential PV systems
