This technical report has been prepared under the supervision of PVPS Task 2 by Luzi Clavadetscher, Thomas Nordmann. This report gives an overview of the system costs of PV systems, based on data collected as part of the IEA PVPS Task 2 Economic Survey and of the operational performance, based on data from the IEA PVPS Performance Database.
The report shows the development of the actual PV system cost and the performance over time for grid-connected PV systems built between 1991 and 2005. The results for the grid-connected PV systems investigated show a trend towards lower system cost and increased performance over this period.
The IEA Photovoltaic Power Systems Programme (PVPS) is one of the collaborative R & D Agreements established within the IEA, and since its establishment in 1993, the PVPS participants have been conducting a variety of joint projects in the application of photovoltaic conversion of solar energy into electricity.
