The international Energy Agency (IEA) founded in November 1974, is an autonomous body -yY]0
within the framework of the Organisation for Economic Co-operation and Development +VHo YEW
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 _u;34H&/
member countries. The European Commission also participates in the work of the Agency. 0f,Ii_k bT
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D o [ nr)
agreements established within the IEA, and since 1993, its Participants have been conducting a \p!mX|
variety of joint projects in the applications of Photovoltaic conversion of solar energy into - [7S.
electricity. BEii:05
The Overall programme is headed by an Executive Committee composed of one representative \05 n$.
from each participating country, while the management of individual research projects (Tasks) RZI4N4o
is the responsibility of Operating Agents. Currently nine Tasks have been established in the -}Gk@=$G

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 4:qM 'z
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV :JG2xtn
systems will continue to represent a significant PV market segment, not only in developing FQikFy(YY
countries, but also in the important home markets of industrial countries. Experts from 15 IEA G+j cR; s
countries are sharing their experiences in this area. o%?~9rf]]
