Foreword A"i $.dR{
The international Energy Agency (IEA) founded in November 1974, is an autonomous body s
a{x.2/o}
within the framework of the Organisation for Economic Co-operation and Development >["X( %&w
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ^?5Ha gA
member countries. The European Commission also participates in the work of the Agency. ,{2= nb[
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D QERj`/g
agreements established within the IEA, and since 1993, its Participants have been conducting a \c4D|7\=
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 9 iV_
electricity. H/}W_ h^^
The Overall programme is headed by an Executive Committee composed of one representative o@sL/5,
from each participating country, while the management of individual research projects (Tasks) &oxHVZ J
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Ubm]V{7
IEA PVPS programme. / tj_WO_
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark " </A) y&
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), =z!/:M

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, @{{6Nd5
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV p^k*[3$0
systems will continue to represent a significant PV market segment, not only in developing l k.Mc6)
countries, but also in the important home markets of industrial countries. Experts from 15 IEA qs {wrem
countries are sharing their experiences in this area. S$ n?
This battery guide is intended for a wide use also close to the end customers to increase the _$_ ,r H
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle _N:GZLG
cost for battery storage in small stand alone photovoltaic systems. Also some basic + CN! 3(r
environmental concerns are addressed. The report has been prepared under the supervision of ]Z?jo# F
