The international Energy Agency (IEA) founded in November 1974, is an autonomous body wB{;b B{
within the framework of the Organisation for Economic Co-operation and Development *cg(
?yg
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 *I0-O*Xr
member countries. The European Commission also participates in the work of the Agency. `3'0I /d"z
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Iu35#j
agreements established within the IEA, and since 1993, its Participants have been conducting a $e BX
variety of joint projects in the applications of Photovoltaic conversion of solar energy into s{4 \xAS>
electricity. &h,5:u
The Overall programme is headed by an Executive Committee composed of one representative aRJ>6Q}
from each participating country, while the management of individual research projects (Tasks) A=-F,=k(!/
is the responsibility of Operating Agents. Currently nine Tasks have been established in the OcSEo7W
IEA PVPS programme. 2. X" f

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, pBC<u
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV z>[tF5
systems will continue to represent a significant PV market segment, not only in developing /)rkiwp
countries, but also in the important home markets of industrial countries. Experts from 15 IEA *$M'`vj:
countries are sharing their experiences in this area. 0J8K9rP;z
