The international Energy Agency (IEA) founded in November 1974, is an autonomous body v JGH8$%;,
within the framework of the Organisation for Economic Co-operation and Development u8KQ V7E
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 -.?

member countries. The European Commission also participates in the work of the Agency. d3q.i5']G
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D mOh?cjOi
agreements established within the IEA, and since 1993, its Participants have been conducting a R|(X_A
variety of joint projects in the applications of Photovoltaic conversion of solar energy into %V ]v,
electricity. B-]bhA4|:
The Overall programme is headed by an Executive Committee composed of one representative 5PZ7-WJ/
from each participating country, while the management of individual research projects (Tasks) 3Fn}nek
is the responsibility of Operating Agents. Currently nine Tasks have been established in the {

IEA PVPS programme. 6>#8 ^{[
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark z-kv{y*Hu

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, )e'F [
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV B *O/>=_
systems will continue to represent a significant PV market segment, not only in developing +g7]ga
countries, but also in the important home markets of industrial countries. Experts from 15 IEA TA/hj>rV
countries are sharing their experiences in this area. H
