The international Energy Agency (IEA) founded in November 1974, is an autonomous body 7?.uAiM'zT
within the framework of the Organisation for Economic Co-operation and Development bz*@[NQ
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 _ @5Xmr
member countries. The European Commission also participates in the work of the Agency. r!r08y f
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ~ua( Qm
agreements established within the IEA, and since 1993, its Participants have been conducting a l*Cul VX
variety of joint projects in the applications of Photovoltaic conversion of solar energy into { FJM c O=
electricity. qe]D4K8`Q3
The Overall programme is headed by an Executive Committee composed of one representative E-A9lJWr
from each participating country, while the management of individual research projects (Tasks) x]^d'o:cDP
is the responsibility of Operating Agents. Currently nine Tasks have been established in the hf`y_H+\7
IEA PVPS programme. cV i _#9u"

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, d59rq<yI
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV >d 5- if
systems will continue to represent a significant PV market segment, not only in developing ?1Nz
,Lc$
countries, but also in the important home markets of industrial countries. Experts from 15 IEA n:AZ(f
countries are sharing their experiences in this area. ;>,B(Xz 4i
This battery guide is intended for a wide use also close to the end customers to increase the 757&bH|a
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 8mX!mYO3c
cost for battery storage in small stand alone photovoltaic systems. Also some basic ko%mZ0Y
environmental concerns are addressed. The report has been prepared under the supervision of D+T/ Z )
