COST AND PERFORMANCE TRENDS IN GRID-CONNECTED PHOTOVOLTAIC SYSTEMS AND CASE STUDIES IEA PVPS Task 2

This technical report has been prepared under the supervision of PVPS Task 2 by: Luzi Clavadetscher, Thomas Nordmann, TNC Consulting AG, Erlenbach, Switzerland; 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 [1]. 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.
