The international Energy Agency (IEA) founded in November 1974, is an autonomous body Dd-;;Y1C
within the framework of the Organisation for Economic Co-operation and Development jL(=<R(~y
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 iS&~oj_-%
member countries. The European Commission also participates in the work of the Agency. zlF*F8>m
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D (o~f6pNB,
agreements established within the IEA, and since 1993, its Participants have been conducting a WPygmti}Be
variety of joint projects in the applications of Photovoltaic conversion of solar energy into M$DJ$G|Z
electricity. C)~YWx@v
The Overall programme is headed by an Executive Committee composed of one representative Fq!12/Nn
from each participating country, while the management of individual research projects (Tasks) (#Z2
is the responsibility of Operating Agents. Currently nine Tasks have been established in the J~eY,n.6]

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ML'4 2z

quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 1@q~(1-o
systems will continue to represent a significant PV market segment, not only in developing daf$`
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Pk9s~}X
countries are sharing their experiences in this area. W.iL!x.B@
This battery guide is intended for a wide use also close to the end customers to increase the -fw0bL%0
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle EF=.L{
cost for battery storage in small stand alone photovoltaic systems. Also some basic lwYk`'
environmental concerns are addressed. The report has been prepared under the supervision of j2# nCU54Z
