Foreword I;xSd.-
The international Energy Agency (IEA) founded in November 1974, is an autonomous body P=3mLz-
within the framework of the Organisation for Economic Co-operation and Development suOWmqLs
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 [G!#y
member countries. The European Commission also participates in the work of the Agency. <|-da&7
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D } ejZk
bP
agreements established within the IEA, and since 1993, its Participants have been conducting a M'gGoH}B+q
variety of joint projects in the applications of Photovoltaic conversion of solar energy into CghlyT
electricity. jD}G9=[$1
The Overall programme is headed by an Executive Committee composed of one representative &|9K~#LVS
from each participating country, while the management of individual research projects (Tasks)
zSd!n
is the responsibility of Operating Agents. Currently nine Tasks have been established in the j !c~%h P
IEA PVPS programme. h~EGRg
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark q4MR9ig1E_
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), <n1panS

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 52,[d P,g
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 8

systems will continue to represent a significant PV market segment, not only in developing X'uQr+p^
countries, but also in the important home markets of industrial countries. Experts from 15 IEA X 0vcBHh
countries are sharing their experiences in this area. sHqa(ynK
This battery guide is intended for a wide use also close to the end customers to increase the ?3

hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 5Z@0XI
cost for battery storage in small stand alone photovoltaic systems. Also some basic y 5{Vx{V"Q
environmental concerns are addressed. The report has been prepared under the supervision of AZ.$g?3w
