The international Energy Agency (IEA) founded in November 1974, is an autonomous body rT;l#<#VE
within the framework of the Organisation for Economic Co-operation and Development o92BGqA>&
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 w-)JCdS6Tb
member countries. The European Commission also participates in the work of the Agency. lgVT~v{U`n
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D *$VeR( QN
agreements established within the IEA, and since 1993, its Participants have been conducting a Tg@G-6u0c
variety of joint projects in the applications of Photovoltaic conversion of solar energy into #+6j-^<_6
electricity. g8Y)90 G
The Overall programme is headed by an Executive Committee composed of one representative t4 ; gY298
from each participating country, while the management of individual research projects (Tasks) j l 7>
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 9 f bo
IEA PVPS programme. )2W7>PY

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Su,<id S
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV py~[M'p(H
systems will continue to represent a significant PV market segment, not only in developing kd&~_=Q
countries, but also in the important home markets of industrial countries. Experts from 15 IEA t`}=~/#`X
countries are sharing their experiences in this area.
