The international Energy Agency (IEA) founded in November 1974, is an autonomous body wY."Lw> 6
within the framework of the Organisation for Economic Co-operation and Development $IZ *|>(
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 X20<r?^,,
member countries. The European Commission also participates in the work of the Agency. y}3

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D @^w!% ?J
agreements established within the IEA, and since 1993, its Participants have been conducting a sE(X:[Am
variety of joint projects in the applications of Photovoltaic conversion of solar energy into <FMu WHY
electricity. KFCQYdI`d
The Overall programme is headed by an Executive Committee composed of one representative \JF57t}Zk
from each participating country, while the management of individual research projects (Tasks) G7Edi;y/{
is the responsibility of Operating Agents. Currently nine Tasks have been established in the %Z-Tb OX
IEA PVPS programme. j@kRv@

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, SLbavP#G
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV _rWTw+
L
systems will continue to represent a significant PV market segment, not only in developing *J*zml3
countries, but also in the important home markets of industrial countries. Experts from 15 IEA >d 1aE)?
countries are sharing their experiences in this area. 8trm`?>
This battery guide is intended for a wide use also close to the end customers to increase the gu~-}
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle \`p |,j
cost for battery storage in small stand alone photovoltaic systems. Also some basic #,Fx@3y\a
environmental concerns are addressed. The report has been prepared under the supervision of FQv02V+&<
