Foreword Ozh^Q$>u
The international Energy Agency (IEA) founded in November 1974, is an autonomous body >8{`q!=|~
within the framework of the Organisation for Economic Co-operation and Development l%)=s~6z
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 O7#}8-@}<u
member countries. The European Commission also participates in the work of the Agency. n3@g{4~
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D [laL6
agreements established within the IEA, and since 1993, its Participants have been conducting a ezNE9g
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 8b#Yd
electricity. C">=2OO
The Overall programme is headed by an Executive Committee composed of one representative t+TbCe
from each participating country, while the management of individual research projects (Tasks) ![."xHVeL
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 'c+qBSDA
IEA PVPS programme. 5/eS1NJ@

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Y.hH
fSp
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV F|ML$
systems will continue to represent a significant PV market segment, not only in developing 1Mhc1MU
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 4~D>oNx4
countries are sharing their experiences in this area. MBTt'6M
This battery guide is intended for a wide use also close to the end customers to increase the jU9zCMyNF
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 2b&;Y /z
cost for battery storage in small stand alone photovoltaic systems. Also some basic {XUfxNDf
environmental concerns are addressed. The report has been prepared under the supervision of 0 VgnN
