Abstract

The scope of this paper is to give an overview of the operational performance and system costs of PV systems from the data collected over a 18-month-period as part of the IEA PVPS Task 2 Economic Survey. The 657 datasets analysed are mainly from small residential grid-connected PV systems and also from some larger gridconnected PV systems from 17 countries, they include freestanding, roof top and facade integrated systems. The PV plants investigated were built between 1983 and 2006. The monitoring period for these plants ranges from 1 to 15 years. Analysis of the data available shows a trend towards lower system cost and a higher performance ratio (PR) over time.
