The international Energy Agency (IEA) founded in November 1974, is an autonomous body .YjrV+om1
within the framework of the Organisation for Economic Co-operation and Development o,CA; _
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 iFnOl*TC
member countries. The European Commission also participates in the work of the Agency. ~X~xE]1o|U
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Wd^lt7(j
agreements established within the IEA, and since 1993, its Participants have been conducting a QxL@'n#5
variety of joint projects in the applications of Photovoltaic conversion of solar energy into UVT >7
electricity. +24|_Lx0
The Overall programme is headed by an Executive Committee composed of one representative B-\,2rCC Z
from each participating country, while the management of individual research projects (Tasks) 2;%#C! TG;
is the responsibility of Operating Agents. Currently nine Tasks have been established in the OAW=Pozr9
IEA PVPS programme. K9C@dvFH

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Q\o$**+{
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV g,n-s+
systems will continue to represent a significant PV market segment, not only in developing ;Na8 _}
countries, but also in the important home markets of industrial countries. Experts from 15 IEA `z3|M#r\;
countries are sharing their experiences in this area. TV1e
