The international Energy Agency (IEA) founded in November 1974, is an autonomous body {e1ak g.
within the framework of the Organisation for Economic Co-operation and Development yLDv/r
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @_+B'<2
member countries. The European Commission also participates in the work of the Agency. V"r2 t9A
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D g~A~|di|
agreements established within the IEA, and since 1993, its Participants have been conducting a t r<iFT}C
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 9(CY"Tc3
electricity. q>E[)\+y
The Overall programme is headed by an Executive Committee composed of one representative t}! Y}D
from each participating country, while the management of individual research projects (Tasks) X<j(AAHE
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Ul/Uk n$
IEA PVPS programme. '; \v:dP
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark BwpSw\\?@

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, }%@q; "9`
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV g Z^'h W-{
systems will continue to represent a significant PV market segment, not only in developing s_p\
bl.
countries, but also in the important home markets of industrial countries. Experts from 15 IEA h3<L,Olp
countries are sharing their experiences in this area. V= ?qU&r<+
This battery guide is intended for a wide use also close to the end customers to increase the `L=d72:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle hA6D*8oXD
cost for battery storage in small stand alone photovoltaic systems. Also some basic T-

environmental concerns are addressed. The report has been prepared under the supervision of !
