Foreword q Xe8K to
The international Energy Agency (IEA) founded in November 1974, is an autonomous body Ab"@7 14@
within the framework of the Organisation for Economic Co-operation and Development p\ZNy\N^
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 sAD}#Zw$
member countries. The European Commission also participates in the work of the Agency. >< $d$(
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 6@0OQ b
agreements established within the IEA, and since 1993, its Participants have been conducting a %k?U9pj^
variety of joint projects in the applications of Photovoltaic conversion of solar energy into [>%xd)8.c
electricity. }YNR"X9*)/
The Overall programme is headed by an Executive Committee composed of one representative qC:raH_:
from each participating country, while the management of individual research projects (Tasks) ,+{LYF
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 4'A!; ]:
IEA PVPS programme. ssxzC4m

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, #& Rw&
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV b8SHg^}
systems will continue to represent a significant PV market segment, not only in developing (l- ab2'
countries, but also in the important home markets of industrial countries. Experts from 15 IEA K[r^'P5m
countries are sharing their experiences in this area. }h!f eP
This battery guide is intended for a wide use also close to the end customers to increase the s`'{I8'p/
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle k $J zH$
cost for battery storage in small stand alone photovoltaic systems. Also some basic :~T99^$zA
environmental concerns are addressed. The report has been prepared under the supervision of &NK,VB;
