The international Energy Agency (IEA) founded in November 1974, is an autonomous body Rn{q/h
within the framework of the Organisation for Economic Co-operation and Development $2BRi@
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 7>{edNy!,
member countries. The European Commission also participates in the work of the Agency. OxF\Hm)(
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D )ymF:]QC
agreements established within the IEA, and since 1993, its Participants have been conducting a eEsEW<su
variety of joint projects in the applications of Photovoltaic conversion of solar energy into HkvCQ H
electricity. 0jv9N6IM
The Overall programme is headed by an Executive Committee composed of one representative if5Y!Tx?G
from each participating country, while the management of individual research projects (Tasks) mUy/lo'4
is the responsibility of Operating Agents. Currently nine Tasks have been established in the jTws0=F*
IEA PVPS programme. 6@2p@eYo

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, qe(X5?#;
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV e;3$7$n Pv
systems will continue to represent a significant PV market segment, not only in developing n 2#uH
countries, but also in the important home markets of industrial countries. Experts from 15 IEA tzpGKhrk6
countries are sharing their experiences in this area. 2|}p&~G(
