Foreword En?V\|,
The international Energy Agency (IEA) founded in November 1974, is an autonomous body aa`(2%(:
within the framework of the Organisation for Economic Co-operation and Development 4hL%J=0:
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 h'):/}JPl
member countries. The European Commission also participates in the work of the Agency. / x 6p
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 6lSz/V;
agreements established within the IEA, and since 1993, its Participants have been conducting a wZiUzS ;v
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ;Y$>WKsV
electricity.

The Overall programme is headed by an Executive Committee composed of one representative xzOa9w/
from each participating country, while the management of individual research projects (Tasks) ;u UFgDi
is the responsibility of Operating Agents. Currently nine Tasks have been established in the QPJ \Iu@D$
IEA PVPS programme. cqS :Zq

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, /kW Z 8Z
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 9\?OV @
systems will continue to represent a significant PV market segment, not only in developing {^VtD
countries, but also in the important home markets of industrial countries. Experts from 15 IEA <'a~ Y3B"o
countries are sharing their experiences in this area. P[nc8z[
This battery guide is intended for a wide use also close to the end customers to increase the py*22Ua^
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle &S,D;uhF
cost for battery storage in small stand alone photovoltaic systems. Also some basic Jz}nV1G(jz
environmental concerns are addressed. The report has been prepared under the supervision of K}~$h ,n
