The international Energy Agency (IEA) founded in November 1974, is an autonomous body U{Xx)l/o
within the framework of the Organisation for Economic Co-operation and Development 0_f6Qrc j
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 N]dsGvX
member countries. The European Commission also participates in the work of the Agency. W }
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 3$n O@rOS
agreements established within the IEA, and since 1993, its Participants have been conducting a x!`~+f.6
variety of joint projects in the applications of Photovoltaic conversion of solar energy into T\OpPSYbl
electricity. JBMJR
The Overall programme is headed by an Executive Committee composed of one representative *1b1phh0/
from each participating country, while the management of individual research projects (Tasks) iebnQf
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ]b&O#D9
IEA PVPS programme. o/\f+iz7

(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), gw_]Y^U
Italy (ITA), Japan (JPN), Korea (KOR), Mexico (MEX), The Netherlands (NLD), Norway =8W'4MC

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 9>!B .Z?!#
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV @ #1T-*
systems will continue to represent a significant PV market segment, not only in developing d#cEAy
countries, but also in the important home markets of industrial countries. Experts from 15 IEA O
<#H5/Tq
countries are sharing their experiences in this area. \wb0%>

This battery guide is intended for a wide use also close to the end customers to increase the &Ndq ^!e
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle TO]7 %aB
cost for battery storage in small stand alone photovoltaic systems. Also some basic aQ#6PO7.Z
environmental concerns are addressed. The report has been prepared under the supervision of .[:2M9Rx
