Foreword 8aKS=(Z!j
The international Energy Agency (IEA) founded in November 1974, is an autonomous body $ M/1pZ
within the framework of the Organisation for Economic Co-operation and Development 2 |JEGyDS-
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 dQ _4aO
member countries. The European Commission also participates in the work of the Agency. ?k($Tc&Q
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D :RxMZwa=
agreements established within the IEA, and since 1993, its Participants have been conducting a ^2{ 6W6=
variety of joint projects in the applications of Photovoltaic conversion of solar energy into u&[L!w
electricity. cd=|P?B i
The Overall programme is headed by an Executive Committee composed of one representative A{ M 7
from each participating country, while the management of individual research projects (Tasks) N%ccy?B
is the responsibility of Operating Agents. Currently nine Tasks have been established in the z] -m<#1
IEA PVPS programme. #XB3Wden2

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, !] E ]Xd<
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV jSH.e?
systems will continue to represent a significant PV market segment, not only in developing JtsXMZz
countries, but also in the important home markets of industrial countries. Experts from 15 IEA VH<d[Mj
countries are sharing their experiences in this area. 5k9

This battery guide is intended for a wide use also close to the end customers to increase the >d &0a:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 5S_fvW;
cost for battery storage in small stand alone photovoltaic systems. Also some basic s6Dkh}:d
environmental concerns are addressed. The report has been prepared under the supervision of :zq Un&k&
