Foreword R ^@`]d X$
The international Energy Agency (IEA) founded in November 1974, is an autonomous body x=K'Jj
within the framework of the Organisation for Economic Co-operation and Development fUq}dAs*K
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ? o]NV
member countries. The European Commission also participates in the work of the Agency. y4n~gTo(?
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D b+Ax Te("
agreements established within the IEA, and since 1993, its Participants have been conducting a XkW@"pf&Fh
variety of joint projects in the applications of Photovoltaic conversion of solar energy into /HqD4GDoug
electricity. fk2Uxg= [
The Overall programme is headed by an Executive Committee composed of one representative e7Gb7c~
from each participating country, while the management of individual research projects (Tasks) ZS3T1

is the responsibility of Operating Agents. Currently nine Tasks have been established in the us8 ce+
IEA PVPS programme. i)'u!V

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, P4MP`A
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV guy!/zQ>A
systems will continue to represent a significant PV market segment, not only in developing EO",|V-
countries, but also in the important home markets of industrial countries. Experts from 15 IEA '/ueY#eG
countries are sharing their experiences in this area. %74f6\
This battery guide is intended for a wide use also close to the end customers to increase the Ex}TDmTu
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle FNl^ lj`Y
cost for battery storage in small stand alone photovoltaic systems. Also some basic "tK3h3/Xv
environmental concerns are addressed. The report has been prepared under the supervision of u 7p:6W
