Foreword $Ifmc` r1
The international Energy Agency (IEA) founded in November 1974, is an autonomous body !*m5F8Qm?A
within the framework of the Organisation for Economic Co-operation and Development i2Y uOV!
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 RIXMJ7e7
member countries. The European Commission also participates in the work of the Agency. (m.ob+D
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D SHbtWq} T
agreements established within the IEA, and since 1993, its Participants have been conducting a 0]=i}wL 8
variety of joint projects in the applications of Photovoltaic conversion of solar energy into u7[ykyV
electricity. ;04Ldb1{|3
The Overall programme is headed by an Executive Committee composed of one representative h\.zdpR
from each participating country, while the management of individual research projects (Tasks) `m>*d!h=
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 7_Z# m (

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, m&\h4$[kql
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV f3{MvAy[
systems will continue to represent a significant PV market segment, not only in developing =p? WBZT|:
countries, but also in the important home markets of industrial countries. Experts from 15 IEA gu<'QV"
countries are sharing their experiences in this area. PBxCx3a{
This battery guide is intended for a wide use also close to the end customers to increase the ->O2I ?
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Q7$.LEioN
cost for battery storage in small stand alone photovoltaic systems. Also some basic 0-|byAh
environmental concerns are addressed. The report has been prepared under the supervision of O .Iu6D
