Foreword Yx5J$!Ld
The international Energy Agency (IEA) founded in November 1974, is an autonomous body .eo~?u<j&
within the framework of the Organisation for Economic Co-operation and Development 8O6_iGTBh
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 || [89G
member countries. The European Commission also participates in the work of the Agency. *C\(wL
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ;{k=C2
agreements established within the IEA, and since 1993, its Participants have been conducting a EY kj@
.,
variety of joint projects in the applications of Photovoltaic conversion of solar energy into -I ?z-?<D
electricity. Q!yb16J
The Overall programme is headed by an Executive Committee composed of one representative dIk'pA^d
from each participating country, while the management of individual research projects (Tasks) AYcgi
is the responsibility of Operating Agents. Currently nine Tasks have been established in the id^|\hDR
IEA PVPS programme. F?z<xL@
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark .d~\Ysve
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), 8lwFAiC8

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, i'HPRY
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 1 tPVP
systems will continue to represent a significant PV market segment, not only in developing R:~(Z?
countries, but also in the important home markets of industrial countries. Experts from 15 IEA zOB !(R
countries are sharing their experiences in this area. S ZlC4=6c
This battery guide is intended for a wide use also close to the end customers to increase the `FZF2.N
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle r|
f-_D
cost for battery storage in small stand alone photovoltaic systems. Also some basic MTb,Kmw<(
environmental concerns are addressed. The report has been prepared under the supervision of w?*z^y@
