The international Energy Agency (IEA) founded in November 1974, is an autonomous body G'|ql5Zw
within the framework of the Organisation for Economic Co-operation and Development uFr12ZFgK
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 t:wBh'K~R8
member countries. The European Commission also participates in the work of the Agency. vQ rxx
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D v[L+PD
U
agreements established within the IEA, and since 1993, its Participants have been conducting a HT<p=o'$Z
variety of joint projects in the applications of Photovoltaic conversion of solar energy into wFM H\a
electricity. I`_2Q:r
The Overall programme is headed by an Executive Committee composed of one representative Jg#0g

from each participating country, while the management of individual research projects (Tasks) T Q41i/{
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ~5

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, .x I Aep_
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ^ZMb Je%L
systems will continue to represent a significant PV market segment, not only in developing !Z_+H<fi+I
countries, but also in the important home markets of industrial countries. Experts from 15 IEA (xgw';g
countries are sharing their experiences in this area. x3n9 |Uud
