The international Energy Agency (IEA) founded in November 1974, is an autonomous body Yt{Y)=_t
within the framework of the Organisation for Economic Co-operation and Development '7xY ,IY
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 \dCdyl6V
member countries. The European Commission also participates in the work of the Agency. )>?K:y8I~
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D x2nNkd0h
agreements established within the IEA, and since 1993, its Participants have been conducting a OgzPX^q/=
variety of joint projects in the applications of Photovoltaic conversion of solar energy into yqAw7GaBN
electricity. M9i u#6P
The Overall programme is headed by an Executive Committee composed of one representative PgxU;N7Y
from each participating country, while the management of individual research projects (Tasks) Lu <'A4Q1
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ~+|p.(I
IEA PVPS programme. 3 =S.-

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, W"~G]a+
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV }F\0Bl&
systems will continue to represent a significant PV market segment, not only in developing YoahqXR `
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 9B F #R<}h
countries are sharing their experiences in this area. .m4K ]^m
