The international Energy Agency (IEA) founded in November 1974, is an autonomous body 7xG~4N<)]
within the framework of the Organisation for Economic Co-operation and Development *1_Ef).
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 TK~ KM
member countries. The European Commission also participates in the work of the Agency. d(b~s2\i
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ST g}

agreements established within the IEA, and since 1993, its Participants have been conducting a :LdPqFXj
variety of joint projects in the applications of Photovoltaic conversion of solar energy into #!#s7^%K &
electricity. "*MF=VB1
The Overall programme is headed by an Executive Committee composed of one representative &Ll&A@yU
from each participating country, while the management of individual research projects (Tasks) #ZnNJ\6
is the responsibility of Operating Agents. Currently nine Tasks have been established in the SdnO#J}{

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, C[#C/@
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ]0|A\bE\S
systems will continue to represent a significant PV market segment, not only in developing ),xD5~_=q
countries, but also in the important home markets of industrial countries. Experts from 15 IEA '^$+G0jv
countries are sharing their experiences in this area. E8p,l>6(f
