In this paper, the performance ratio (PR) of PV system is evaluated by field testing. The sampling strategy of efficiency chain for PV system is determined by analyzing long-term operation monitoring data of PV system. The efficiency parameters of components are extracted. The efficiency model of components in PV system is established in PVsyst software. Combining efficiency models, geographic information and the long time weather information, the PR of PV system and the yield over the next twenty-five years can be evaluated.

This paper evaluates PV system performance ratio and yield over the next 25 years by field testing, analyzing long-term operation monitoring data, and using efficiency models and geographic information.
