The international Energy Agency (IEA) founded in November 1974, is an autonomous body QrRCsy70
within the framework of the Organisation for Economic Co-operation and Development e2H'uMy;&
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 3R96;d;
member countries. The European Commission also participates in the work of the Agency. \y+F!;IxL
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D v t7C
agreements established within the IEA, and since 1993, its Participants have been conducting a E rUk>V
variety of joint projects in the applications of Photovoltaic conversion of solar energy into aIyY %QT
electricity. "g&l~N1$
The Overall programme is headed by an Executive Committee composed of one representative dJgOfg^
from each participating country, while the management of individual research projects (Tasks) H5rNLfw
'
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Kwmo)|7uPU
IEA PVPS programme. 1 jd=R7

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, *fyEw\`a
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV <i @jD
systems will continue to represent a significant PV market segment, not only in developing <\Dl#DH
countries, but also in the important home markets of industrial countries. Experts from 15 IEA k.V OS 0
countries are sharing their experiences in this area. 8J @OMW&[l
This battery guide is intended for a wide use also close to the end customers to increase the
oEf^o*5(
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle m,"tdVo .
cost for battery storage in small stand alone photovoltaic systems. Also some basic "pJ EzC
environmental concerns are addressed. The report has been prepared under the supervision of Lr]Hvd
