Foreword #Bg88!-4
The international Energy Agency (IEA) founded in November 1974, is an autonomous body (#BkL:dg
within the framework of the Organisation for Economic Co-operation and Development _Buwz_[&
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 e ,/I}W
member countries. The European Commission also participates in the work of the Agency. }\:3}'S.$
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D LU l6^J U
agreements established within the IEA, and since 1993, its Participants have been conducting a =zDU !< U
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Yew n
electricity. -/ ; y *mP
The Overall programme is headed by an Executive Committee composed of one representative C$vKRg\o
from each participating country, while the management of individual research projects (Tasks) -X'HZ\)
is the responsibility of Operating Agents. Currently nine Tasks have been established in the M")J buI
IEA PVPS programme. ,3.E]_3 xX

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, KoRJ'WW^
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV h$)(-_c3
systems will continue to represent a significant PV market segment, not only in developing (wEaa'XL
countries, but also in the important home markets of industrial countries. Experts from 15 IEA l)[\TD
countries are sharing their experiences in this area. jGl8y!aM
This battery guide is intended for a wide use also close to the end customers to increase the _7'9 omq@
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ;n%SjQ'%
cost for battery storage in small stand alone photovoltaic systems. Also some basic ];Z)=y,vM
environmental concerns are addressed. The report has been prepared under the supervision of :'91qA%Wr
