The international Energy Agency (IEA) founded in November 1974, is an autonomous body N K.] yw'
within the framework of the Organisation for Economic Co-operation and Development N#
$ob 9
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 C)66 ^l!x
member countries. The European Commission also participates in the work of the Agency. ZT;$aNy
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D CmKbpN*
agreements established within the IEA, and since 1993, its Participants have been conducting a # InuN8sI
variety of joint projects in the applications of Photovoltaic conversion of solar energy into yXyL,R
electricity. f*U3s N^y
The Overall programme is headed by an Executive Committee composed of one representative _dCdyf
from each participating country, while the management of individual research projects (Tasks) 1'ts>6b
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 3BHPD; U
IEA PVPS programme. I~ Q2jg2
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark ([\mnL<FC

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, %<c2jvn+k
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV [H ^ ktF
systems will continue to represent a significant PV market segment, not only in developing tP/0_^m
countries, but also in the important home markets of industrial countries. Experts from 15 IEA WrJgU&H{
countries are sharing their experiences in this area. ;w0|ev 6|
This battery guide is intended for a wide use also close to the end customers to increase the KU:RS+,e;
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ((OQs .
cost for battery storage in small stand alone photovoltaic systems. Also some basic ZYf0FC=-
environmental concerns are addressed. The report has been prepared under the supervision of zpi
