The international Energy Agency (IEA) founded in November 1974, is an autonomous body PcXz4?Q$
within the framework of the Organisation for Economic Co-operation and Development +tbG^w%
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 w1Z9@*C!
member countries. The European Commission also participates in the work of the Agency. C;#-2^h
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D b?6-lYE>L
agreements established within the IEA, and since 1993, its Participants have been conducting a I]HrtI
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ^Ge3"^x1
electricity. ]>E)0<t
The Overall programme is headed by an Executive Committee composed of one representative 0n5{Wr$
from each participating country, while the management of individual research projects (Tasks) `|Aj3a3sND
is the responsibility of Operating Agents. Currently nine Tasks have been established in the jf_xm=n
IEA PVPS programme. uJ Q#l\t
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark sW'SR
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), 7Y`/w$

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, -;5WMX6
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV oPSucz&s
systems will continue to represent a significant PV market segment, not only in developing HAq
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 'CE3
|x\%K
countries are sharing their experiences in this area. f+#^Lngo
This battery guide is intended for a wide use also close to the end customers to increase the `Sh#>
Jp
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 1SddZ5
cost for battery storage in small stand alone photovoltaic systems. Also some basic $a'n{EP
environmental concerns are addressed. The report has been prepared under the supervision of X,m6#vLK2
