The international Energy Agency (IEA) founded in November 1974, is an autonomous body H~ n~5 sF"
within the framework of the Organisation for Economic Co-operation and Development F LI8r:
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 %@n8

member countries. The European Commission also participates in the work of the Agency. ([b!$o<v
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D |qcFmy
agreements established within the IEA, and since 1993, its Participants have been conducting a ]^jdO# #M
variety of joint projects in the applications of Photovoltaic conversion of solar energy into c[_^bs>k
electricity. !]+Z%e d`%
The Overall programme is headed by an Executive Committee composed of one representative e>9Z:vY
from each participating country, while the management of individual research projects (Tasks) 7'i#!5
is the responsibility of Operating Agents. Currently nine Tasks have been established in the wZ8 MhE
IEA PVPS programme. A ]Tcj^#
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark fGf-fh;s

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, HJaw\zbL
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV RE

systems will continue to represent a significant PV market segment, not only in developing 2 ?- 07 g
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 6$s0-{^
countries are sharing their experiences in this area. k\sM;bCv7
This battery guide is intended for a wide use also close to the end customers to increase the x2;i<

hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle >q@ Sd
cost for battery storage in small stand alone photovoltaic systems. Also some basic 1Uemsx%'k
environmental concerns are addressed. The report has been prepared under the supervision of FaE # \Q
