The international Energy Agency (IEA) founded in November 1974, is an autonomous body !]"M]tyv\
within the framework of the Organisation for Economic Co-operation and Development k=t{o
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 QBmARQ
member countries. The European Commission also participates in the work of the Agency. c&#Q`m
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D hRKJKQ@7
agreements established within the IEA, and since 1993, its Participants have been conducting a W;Dik%^tg
variety of joint projects in the applications of Photovoltaic conversion of solar energy into `$4wm0G|
electricity. X$%[%q8qg
The Overall programme is headed by an Executive Committee composed of one representative .4 NcaMj
from each participating country, while the management of individual research projects (Tasks) 5a6d3u/
is the responsibility of Operating Agents. Currently nine Tasks have been established in the K\}qYdPF
IEA PVPS programme. 0I)eYksh

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, sNG 7fi.|
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV DbI)tDi5D
systems will continue to represent a significant PV market segment, not only in developing G"J
8i|~
countries, but also in the important home markets of industrial countries. Experts from 15 IEA =J-&usX
countries are sharing their experiences in this area. abVEi[nP
This battery guide is intended for a wide use also close to the end customers to increase the 5[6{o$I
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle L$Xkx03lz>
cost for battery storage in small stand alone photovoltaic systems. Also some basic +IGSOWL
environmental concerns are addressed. The report has been prepared under the supervision of NHdNCHhA>-
