The international Energy Agency (IEA) founded in November 1974, is an autonomous body zc rY>t#l
within the framework of the Organisation for Economic Co-operation and Development ^ D%FX!$
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Zf$Np50@(
member countries. The European Commission also participates in the work of the Agency. Gg Jf7ie4
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D f| _u7"OX
agreements established within the IEA, and since 1993, its Participants have been conducting a t>=fTkB
variety of joint projects in the applications of Photovoltaic conversion of solar energy into VTy9_~q
electricity. El\%E"Tk%
The Overall programme is headed by an Executive Committee composed of one representative JjaoOe
from each participating country, while the management of individual research projects (Tasks) I$q]. B
is the responsibility of Operating Agents. Currently nine Tasks have been established in the wX >*H
IEA PVPS programme. I9h ?;(
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark 'R-3fO???
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), (T`E!A0I\?

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ;AO#xv+#
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV V |(H|9
systems will continue to represent a significant PV market segment, not only in developing 4=<tWa|@9
countries, but also in the important home markets of industrial countries. Experts from 15 IEA I:K"'R^
countries are sharing their experiences in this area. ^[:p|U2mA
