The international Energy Agency (IEA) founded in November 1974, is an autonomous body ^R\et.W`s
within the framework of the Organisation for Economic Co-operation and Development ,_HSvs7-
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 b[+G+V
member countries. The European Commission also participates in the work of the Agency. e} | UVoeH
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D }yM /z
agreements established within the IEA, and since 1993, its Participants have been conducting a >KF1 ]/y<
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Gao8!OaQ
electricity. H/!_D f
The Overall programme is headed by an Executive Committee composed of one representative k.Tu# 7
from each participating country, while the management of individual research projects (Tasks) Q' ? { _
is the responsibility of Operating Agents. Currently nine Tasks have been established in the s$g"6;_\
IEA PVPS programme. 7R9S %

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 02g!mJW>}y
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 5Ym/'eT
systems will continue to represent a significant PV market segment, not only in developing *}BaO*A
countries, but also in the important home markets of industrial countries. Experts from 15 IEA vZEeb j
countries are sharing their experiences in this area. [x}]sT`#a
