The international Energy Agency (IEA) founded in November 1974, is an autonomous body o j /:
within the framework of the Organisation for Economic Co-operation and Development ,F`:4=H %
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 6q RZ#MC
member countries. The European Commission also participates in the work of the Agency. rj&
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 6TvlK*<r=
agreements established within the IEA, and since 1993, its Participants have been conducting a ?vuM'UH-
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ,R5NKWo
electricity. *

The Overall programme is headed by an Executive Committee composed of one representative ]X?~Cz/wl
from each participating country, while the management of individual research projects (Tasks) L:"i,K#P
is the responsibility of Operating Agents. Currently nine Tasks have been established in the qcEi J}-
IEA PVPS programme. TK<~ (Dk

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, }2:/&H'
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ]#]|]>&

systems will continue to represent a significant PV market segment, not only in developing R|
