The international Energy Agency (IEA) founded in November 1974, is an autonomous body c\ l kD-\
within the framework of the Organisation for Economic Co-operation and Development C>*u()q>4h
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 *bA. zm zM
member countries. The European Commission also participates in the work of the Agency. u:_,GQ )\
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D jtc]>]6i
agreements established within the IEA, and since 1993, its Participants have been conducting a @6T/Tdz
variety of joint projects in the applications of Photovoltaic conversion of solar energy into kpN)zxf k
electricity. 7O-x<P;
The Overall programme is headed by an Executive Committee composed of one representative :G%61x&=Zc
from each participating country, while the management of individual research projects (Tasks) .ctw 2x5W
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Hja3a{LH
IEA PVPS programme. v

Task III of the PVPS programme, active since 1993, focuses on the exchange of information,

quality assurance and technical surveys on stand alone PV applications. Stand-alone PV +!.^zp21
systems will continue to represent a significant PV market segment, not only in developing _>X+ZlpU:
countries, but also in the important home markets of industrial countries. Experts from 15 IEA b!5~7Ub.No
countries are sharing their experiences in this area. ,wAF:7'
