The international Energy Agency (IEA) founded in November 1974, is an autonomous body _
kSPUP5
within the framework of the Organisation for Economic Co-operation and Development ]1|Ql*6y,
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 kl3S~gE4@
member countries. The European Commission also participates in the work of the Agency. A;WwS?fyQ
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D E%\7Uo-
agreements established within the IEA, and since 1993, its Participants have been conducting a
b~Pxgfu"
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 0.BUfuuh
electricity. BU A 6(
The Overall programme is headed by an Executive Committee composed of one representative Sd<@X@iU8D
from each participating country, while the management of individual research projects (Tasks) Jf P\7
is the responsibility of Operating Agents. Currently nine Tasks have been established in the :OQ:@Yk
IEA PVPS programme. 2hwXWTSu

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, _]D#)-uv}C
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Vyt~OT I\
systems will continue to represent a significant PV market segment, not only in developing ' =K of1
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Il^ \3T+
countries are sharing their experiences in this area. ,JQxs7 @2k
This battery guide is intended for a wide use also close to the end customers to increase the 'Elj"Iiu
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle h\u0{!@}
cost for battery storage in small stand alone photovoltaic systems. Also some basic ,y8I)+
environmental concerns are addressed. The report has been prepared under the supervision of ] zvVY:v
