The international Energy Agency (IEA) founded in November 1974, is an autonomous body *F|+2?a:$
within the framework of the Organisation for Economic Co-operation and Development }_]As}E
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 gw J}]Tf
member countries. The European Commission also participates in the work of the Agency. \imp7}N
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D *_#&"(P
agreements established within the IEA, and since 1993, its Participants have been conducting a 0mVuD\#=!
variety of joint projects in the applications of Photovoltaic conversion of solar energy into PF6 7z]<o
electricity. @.1 Qs`pt
The Overall programme is headed by an Executive Committee composed of one representative ng

from each participating country, while the management of individual research projects (Tasks) <"A#Eok|4
is the responsibility of Operating Agents. Currently nine Tasks have been established in the nNu[c[V
IEA PVPS programme. 0Gx*'B=

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, r_q~'r35 _
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ;AltNGcM
systems will continue to represent a significant PV market segment, not only in developing j
C9<hLt
countries, but also in the important home markets of industrial countries. Experts from 15 IEA nSS}%&a:LX
countries are sharing their experiences in this area. ?;fv !'?%
