The international Energy Agency (IEA) founded in November 1974, is an autonomous body ~,.}@XlgT.
within the framework of the Organisation for Economic Co-operation and Development UK xeN[fv
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 VjVL/SO/
member countries. The European Commission also participates in the work of the Agency. WKPuI E:
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D .FXn=4l'vV
agreements established within the IEA, and since 1993, its Participants have been conducting a !>5!Fb=Sy
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 14v,z;HXj
electricity. gkyv [
The Overall programme is headed by an Executive Committee composed of one representative @z)_m!yV1
from each participating country, while the management of individual research projects (Tasks) *z

is the responsibility of Operating Agents. Currently nine Tasks have been established in the 7 V+rQ
IEA PVPS programme. }PDNW

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, f#9\&-h e0
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV pP6pn~ }
systems will continue to represent a significant PV market segment, not only in developing %A<|@OSdOa
countries, but also in the important home markets of industrial countries. Experts from 15 IEA _=ee Z4f
countries are sharing their experiences in this area. x
