Foreword x@;XyQq
The international Energy Agency (IEA) founded in November 1974, is an autonomous body j *Ta?'*
within the framework of the Organisation for Economic Co-operation and Development ;^^u _SuH
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ={o>g '
member countries. The European Commission also participates in the work of the Agency. hCD0Zel
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ;$wS<zp6
agreements established within the IEA, and since 1993, its Participants have been conducting a #KF:(2
variety of joint projects in the applications of Photovoltaic conversion of solar energy into No=Ig-It
electricity. $pyM<:*L&<
The Overall programme is headed by an Executive Committee composed of one representative DGz'Dn
from each participating country, while the management of individual research projects (Tasks) 7<<pP
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 8 $io^n\i
IEA PVPS programme. h

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Z,M?!vK
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV <UQaRI[55
systems will continue to represent a significant PV market segment, not only in developing '>^ +_|2
countries, but also in the important home markets of industrial countries. Experts from 15 IEA sU^2I v\%
countries are sharing their experiences in this area. UeIu

This battery guide is intended for a wide use also close to the end customers to increase the hPE#l?H@A
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Ok/~E
cost for battery storage in small stand alone photovoltaic systems. Also some basic m\(4y G j
environmental concerns are addressed. The report has been prepared under the supervision of >Vy=5)/i
