The international Energy Agency (IEA) founded in November 1974, is an autonomous body e4=FO;%
within the framework of the Organisation for Economic Co-operation and Development L ,A+"
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 n yPeN?-
member countries. The European Commission also participates in the work of the Agency. yOz6a :r
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D d%k7n+ICQ4
agreements established within the IEA, and since 1993, its Participants have been conducting a v *Gd=\88
variety of joint projects in the applications of Photovoltaic conversion of solar energy into F&!vtlV)
electricity. cy@R i#
The Overall programme is headed by an Executive Committee composed of one representative sTP\ }
from each participating country, while the management of individual research projects (Tasks) t! 3s@
is the responsibility of Operating Agents. Currently nine Tasks have been established in the &=)O:Jfa
IEA PVPS programme. l9uocP:D

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, giu{,gS0?M
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV =$4I} 2
systems will continue to represent a significant PV market segment, not only in developing iw M xTty
countries, but also in the important home markets of industrial countries. Experts from 15 IEA LQ k^l`
countries are sharing their experiences in this area. *;}xg{@
This battery guide is intended for a wide use also close to the end customers to increase the (rhlK}

hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ',g%L_8Sq
cost for battery storage in small stand alone photovoltaic systems. Also some basic hO[_ _j8
