The international Energy Agency (IEA) founded in November 1974, is an autonomous body dy>!KO
within the framework of the Organisation for Economic Co-operation and Development +iO /m
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 A,gEM4
member countries. The European Commission also participates in the work of the Agency. 0N :XIGFa
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Wu1 {[a|
agreements established within the IEA, and since 1993, its Participants have been conducting a *G5c | Y
variety of joint projects in the applications of Photovoltaic conversion of solar energy into XORk!m|
electricity. 'gs o'&Uaj
The Overall programme is headed by an Executive Committee composed of one representative ut2 ~rRiK
from each participating country, while the management of individual research projects (Tasks) !j:`7PT\
is the responsibility of Operating Agents. Currently nine Tasks have been established in the kAA>FI6
IEA PVPS programme. OJAIaC\
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark PVOx`<ng
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), qk/:A+

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, zj{r^D$
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV XT>.`, sv
systems will continue to represent a significant PV market segment, not only in developing g\SrO {*
countries, but also in the important home markets of industrial countries. Experts from 15 IEA _<c$)1
countries are sharing their experiences in this area. Cq)IayD@
This battery guide is intended for a wide use also close to the end customers to increase the "= / f$Xf
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle &opd2
cost for battery storage in small stand alone photovoltaic systems. Also some basic LE6.nmvS
environmental concerns are addressed. The report has been prepared under the supervision of KhbYr$
