The international Energy Agency (IEA) founded in November 1974, is an autonomous body xY U .D+RY
within the framework of the Organisation for Economic Co-operation and Development 92d6U2T4&
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 WxJf{=-
member countries. The European Commission also participates in the work of the Agency. X

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, I,VH=Yn5,
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV VX+jadYdq
systems will continue to represent a significant PV market segment, not only in developing n;p:=\uN
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ]f: v,a
countries are sharing their experiences in this area. J}@z_^|"mJ
