The international Energy Agency (IEA) founded in November 1974, is an autonomous body %kUIIH V}
within the framework of the Organisation for Economic Co-operation and Development X180_Kt2
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 =98@MX%P
member countries. The European Commission also participates in the work of the Agency. Bf.@B0\
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D t
?rUbN
agreements established within the IEA, and since 1993, its Participants have been conducting a h",kA(+P
variety of joint projects in the applications of Photovoltaic conversion of solar energy into THC34u]
electricity. y]+q mNw"+
The Overall programme is headed by an Executive Committee composed of one representative }<m9w\pA
from each participating country, while the management of individual research projects (Tasks) UH2fP G
is the responsibility of Operating Agents. Currently nine Tasks have been established in the _3.=| @L
IEA PVPS programme. z^bv)u
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark _DS_AW}D

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ;.+sz(:hm
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV |bA\>%~
systems will continue to represent a significant PV market segment, not only in developing r Z%l?(
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 1$H*E~
countries are sharing their experiences in this area. eh` n?C
This battery guide is intended for a wide use also close to the end customers to increase the qXcHf6
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle d?) k<!fJk
cost for battery storage in small stand alone photovoltaic systems. Also some basic ye4 T2=
environmental concerns are addressed. The report has been prepared under the supervision of [f 4Nq \i
