Energy performance assessment of a semi-integrated PV system in a zero emission building through periodic linear regression method

In this paper, the performance analysis of the PV system is carried out considering the six months in the first year of operation of the system. A graphical analysis based on the linear regression method is presented and the array yield is compared against the reference yield (Performance Ratio). The analysis gives a general overview of the performance of the system, and a focus is then placed on the understanding of the system's output in relation to the undersizing of the PV inverters.
