The international Energy Agency (IEA) founded in November 1974, is an autonomous body @s!9 T
within the framework of the Organisation for Economic Co-operation and Development YSwAu,$jf
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 9n{tbabJ
member countries. The European Commission also participates in the work of the Agency. w"d~R
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D XH4!|wz
agreements established within the IEA, and since 1993, its Participants have been conducting a Qj: D=j8
variety of joint projects in the applications of Photovoltaic conversion of solar energy into p pr95 Y]^
electricity. *0]E4]ZO
The Overall programme is headed by an Executive Committee composed of one representative Awl4*J~
from each participating country, while the management of individual research projects (Tasks) kG_ K &,;@
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Ug>yTc_(7
IEA PVPS programme. ^2E\{$J

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, m[ *)sm
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV "j BrPCB
