Foreword V1>94/waa
The international Energy Agency (IEA) founded in November 1974, is an autonomous body vhEs + j
within the framework of the Organisation for Economic Co-operation and Development lKwT5ma7
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @Be: +01z
member countries. The European Commission also participates in the work of the Agency. !X < n:J
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D !skiD}zd1
agreements established within the IEA, and since 1993, its Participants have been conducting a hPpXB:(-0
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 2^ZPO4|
electricity. Aq]'.J =4
The Overall programme is headed by an Executive Committee composed of one representative GXK?7S0H
from each participating country, while the management of individual research projects (Tasks) 3M*[a~
is the responsibility of Operating Agents. Currently nine Tasks have been established in the y]Tn#4 ,/
IEA PVPS programme. ;f^jB;\<
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark 0a%u i2k
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), "K!BJQ

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, FEmlC,%
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ~ A|*]0,
systems will continue to represent a significant PV market segment, not only in developing [:S F(*}
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Du4# \OK
countries are sharing their experiences in this area. h1o+7
This battery guide is intended for a wide use also close to the end customers to increase the B "zg85

hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle =F[,-B~
cost for battery storage in small stand alone photovoltaic systems. Also some basic 2`U&,,-Mf
environmental concerns are addressed. The report has been prepared under the supervision of eSBf;lr=
