Foreword rRgP/E#_
The international Energy Agency (IEA) founded in November 1974, is an autonomous body 7S'3U}Y>VX
within the framework of the Organisation for Economic Co-operation and Development 0@cc XF E
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 x"7`,W
member countries. The European Commission also participates in the work of the Agency. :j o

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Teo&V
agreements established within the IEA, and since 1993, its Participants have been conducting a *% 6NuZ
variety of joint projects in the applications of Photovoltaic conversion of solar energy into />FgDIO
electricity. =GGt:3Kx-
The Overall programme is headed by an Executive Committee composed of one representative j6@5"wx
from each participating country, while the management of individual research projects (Tasks) afE`GG-
is the responsibility of Operating Agents. Currently nine Tasks have been established in the iPoh 2
IEA PVPS programme. vMT:j

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, "lU%Pm]>
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV JrZ"AId2
systems will continue to represent a significant PV market segment, not only in developing h0;PtQb1
countries, but also in the important home markets of industrial countries. Experts from 15 IEA +T\c <lJ9
countries are sharing their experiences in this area. >M1m(u84#
