The international Energy Agency (IEA) founded in November 1974, is an autonomous body \( LKLlam
within the framework of the Organisation for Economic Co-operation and Development vHZw{'5y
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 :(c2YZ
member countries. The European Commission also participates in the work of the Agency. )@RTU~#
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ]0G OSh
agreements established within the IEA, and since 1993, its Participants have been conducting a 1uG?R
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 57'=Qz52
electricity. .Kv>*__-Q
The Overall programme is headed by an Executive Committee composed of one representative #r `hK)
from each participating country, while the management of individual research projects (Tasks) {d.`0v9h
is the responsibility of Operating Agents. Currently nine Tasks have been established in the WIb\ +!

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 7 6~x|6)
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV L}ud+Wfox
systems will continue to represent a significant PV market segment, not only in developing z%Ywjfn'
countries, but also in the important home markets of industrial countries. Experts from 15 IEA .L0pS.=LT
countries are sharing their experiences in this area. L01 R.3Z+
