The international Energy Agency (IEA) founded in November 1974, is an autonomous body q/9H..6
within the framework of the Organisation for Economic Co-operation and Development . 5y"38e
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 X!hIwi A,t
member countries. The European Commission also participates in the work of the Agency. 38ES($
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D CbBSF KM
agreements established within the IEA, and since 1993, its Participants have been conducting a = {'pUU
variety of joint projects in the applications of Photovoltaic conversion of solar energy into W<ZK,kv
electricity. \2-@' ^i
The Overall programme is headed by an Executive Committee composed of one representative rHge~nY<
from each participating country, while the management of individual research projects (Tasks) 4LcX<B U9
is the responsibility of Operating Agents. Currently nine Tasks have been established in the `A$!]&[~|
IEA PVPS programme. lT&wO m3
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark 8F(h*e_?

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, n"PJ,a o
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV `N//A}9
systems will continue to represent a significant PV market segment, not only in developing TcTM]ixr
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Cb t{ H}I3
countries are sharing their experiences in this area. )4U> !KrY
This battery guide is intended for a wide use also close to the end customers to increase the rPNb\ Ri
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle f*{

cost for battery storage in small stand alone photovoltaic systems. Also some basic r~-.nb"P
environmental concerns are addressed. The report has been prepared under the supervision of v44}%$
