The international Energy Agency (IEA) founded in November 1974, is an autonomous body n 8
K6m (
within the framework of the Organisation for Economic Co-operation and Development DJAKF
(OECD) which carries out a comprehensive programme of energy co-operation among its 23

member countries. The European Commission also participates in the work of the Agency. p<,`l)o}~
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Y*S:/b~y
agreements established within the IEA, and since 1993, its Participants have been conducting a 1Kd6tnX
variety of joint projects in the applications of Photovoltaic conversion of solar energy into =itQ@ ``r
electricity. t[@>u'YKt
The Overall programme is headed by an Executive Committee composed of one representative 5pK
_-:?
from each participating country, while the management of individual research projects (Tasks) n9n)eI)R
is the responsibility of Operating Agents. Currently nine Tasks have been established in the A7|L|+ ?
IEA PVPS programme. z,4 D' F&
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark sx}S,aIU

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 1ANb=X|hig
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ' t5`Ni
systems will continue to represent a significant PV market segment, not only in developing CPMGsW^
countries, but also in the important home markets of industrial countries. Experts from 15 IEA SD<a#S\o
countries are sharing their experiences in this area. ?~!9\dek,
This battery guide is intended for a wide use also close to the end customers to increase the >?rMMR+A
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 1hE{(onI
cost for battery storage in small stand alone photovoltaic systems. Also some basic $*T?}r>
environmental concerns are addressed. The report has been prepared under the supervision of UGj | )/
