The international Energy Agency (IEA) founded in November 1974, is an autonomous body @:+n 6
within the framework of the Organisation for Economic Co-operation and Development t"/"Ge# a
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 b+].Uc
member countries. The European Commission also participates in the work of the Agency. eM=) >zl
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ; [%}Xx
agreements established within the IEA, and since 1993, its Participants have been conducting a l$VxE'&LQ
variety of joint projects in the applications of Photovoltaic conversion of solar energy into OI_/7@L
electricity. VnSj:LUD
The Overall programme is headed by an Executive Committee composed of one representative iW1ih Q X
from each participating country, while the management of individual research projects (Tasks) QeeC 2
is the responsibility of Operating Agents. Currently nine Tasks have been established in the hL bT\J`I
IEA PVPS programme.

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 5m.KtnT)
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV qIGu#zX W
systems will continue to represent a significant PV market segment, not only in developing J'ZFIT_>
countries, but also in the important home markets of industrial countries. Experts from 15 IEA T dP{{&'9
countries are sharing their experiences in this area. qN1 -plY
This battery guide is intended for a wide use also close to the end customers to increase the N _~KZQ11^
