The international Energy Agency (IEA) founded in November 1974, is an autonomous body *L!!]Q2c
within the framework of the Organisation for Economic Co-operation and Development TX#m&vh
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 >I=2!C1w
member countries. The European Commission also participates in the work of the Agency. |HZT N"
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D >[X{LI(_<<
agreements established within the IEA, and since 1993, its Participants have been conducting a 7Pa@1']
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 52o x`t |
electricity. *OQG 4aWy
The Overall programme is headed by an Executive Committee composed of one representative LzYO$Ir:g
from each participating country, while the management of individual research projects (Tasks) *5xJv
is the responsibility of Operating Agents. Currently nine Tasks have been established in the +f[ED4E>'(
IEA PVPS programme. 02Ia2e.f
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark vf8\i- U=

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, JMTvSXr
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV u :F~K
systems will continue to represent a significant PV market segment, not only in developing 7.j[ a*^
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 5+f LeC;
countries are sharing their experiences in this area. f-r]
