The international Energy Agency (IEA) founded in November 1974, is an autonomous body ,MHK|8!
within the framework of the Organisation for Economic Co-operation and Development sz%]rN6$
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @RB^m(> 5
member countries. The European Commission also participates in the work of the Agency. &iD&C>;pf
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D I5j|\ /Ht
agreements established within the IEA, and since 1993, its Participants have been conducting a 6GAEQ]
variety of joint projects in the applications of Photovoltaic conversion of solar energy into }`Wo(E}O
electricity. QX?moW6UW
The Overall programme is headed by an Executive Committee composed of one representative BV<_1WT}
from each participating country, while the management of individual research projects (Tasks) p}~Sgi
is the responsibility of Operating Agents. Currently nine Tasks have been established in the fvta<
IEA PVPS programme. b!-=L&V
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark 'ym Mu}q

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, `+."X1
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV !`H!!Kg0L
systems will continue to represent a significant PV market segment, not only in developing - ]/=WAOK
countries, but also in the important home markets of industrial countries. Experts from 15 IEA v"Bm4+c&0
countries are sharing their experiences in this area. 18~jUYMV
This battery guide is intended for a wide use also close to the end customers to increase the Wf?[GO
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle HXh:83
cost for battery storage in small stand alone photovoltaic systems. Also some basic <QgpePyoN
environmental concerns are addressed. The report has been prepared under the supervision of \u6.*w5TI
