The international Energy Agency (IEA) founded in November 1974, is an autonomous body vx\r!]
within the framework of the Organisation for Economic Co-operation and Development +\x,HsUc"
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 PYiU_
member countries. The European Commission also participates in the work of the Agency. 6 0 P<4
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D FSP+?((
agreements established within the IEA, and since 1993, its Participants have been conducting a {]*c29b>
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ph QU D
electricity. UMv.{iEj
The Overall programme is headed by an Executive Committee composed of one representative 16w|O |^<
from each participating country, while the management of individual research projects (Tasks) { SOr#{1z*
is the responsibility of Operating Agents. Currently nine Tasks have been established in the +ndaLhj'
IEA PVPS programme. ksc;X$f&4

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, B#exHf8
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 7jxslI&F
systems will continue to represent a significant PV market segment, not only in developing $:BKzHm g
countries, but also in the important home markets of industrial countries. Experts from 15 IEA H
>j
countries are sharing their experiences in this area. QFE :tBHe
