The international Energy Agency (IEA) founded in November 1974, is an autonomous body ggt DN{t
within the framework of the Organisation for Economic Co-operation and Development Z'pQ^MO
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 sDqe(x}a
member countries. The European Commission also participates in the work of the Agency. %zC[KE*~
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D o gM%N
agreements established within the IEA, and since 1993, its Participants have been conducting a
|eoid ?=
variety of joint projects in the applications of Photovoltaic conversion of solar energy into #5sD{:f`
electricity. qP!eJ6[Nh"
The Overall programme is headed by an Executive Committee composed of one representative qZ @0]"h
from each participating country, while the management of individual research projects (Tasks) Mv|yk Joz"
is the responsibility of Operating Agents. Currently nine Tasks have been established in the uBg 8h{>
IEA PVPS programme. 6Dws,_UAZ4

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ,!G{ 5FF8:
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ?&WYjTU]H
systems will continue to represent a significant PV market segment, not only in developing "wH) mQnd
countries, but also in the important home markets of industrial countries. Experts from 15 IEA M|T4~Q U&
countries are sharing their experiences in this area. aRj>iQaddx
This battery guide is intended for a wide use also close to the end customers to increase the e"-X U@`k1
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle +y[@ T6_
cost for battery storage in small stand alone photovoltaic systems. Also some basic nGZX7Fx5
environmental concerns are addressed. The report has been prepared under the supervision of < V\Y@Ei+
