The international Energy Agency (IEA) founded in November 1974, is an autonomous body uXQ7eXX
within the framework of the Organisation for Economic Co-operation and Development %Rd~|$@>x
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 -B *<Q[_
member countries. The European Commission also participates in the work of the Agency. xH"W}- #[
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 'H Q7
|Je
agreements established within the IEA, and since 1993, its Participants have been conducting a p iYws<Q
variety of joint projects in the applications of Photovoltaic conversion of solar energy into S2'`|uI
electricity. +EST58
The Overall programme is headed by an Executive Committee composed of one representative ' 1P=^
from each participating country, while the management of individual research projects (Tasks) ^A *]&%(h
is the responsibility of Operating Agents. Currently nine Tasks have been established in the t,=@hs

IEA PVPS programme. 4-]Do?

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, z-KrQx2
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV T6h;Y
systems will continue to represent a significant PV market segment, not only in developing t$]&,ucW#
countries, but also in the important home markets of industrial countries. Experts from 15 IEA `ICcaRIN8I
countries are sharing their experiences in this area. lFp!XZ!
This battery guide is intended for a wide use also close to the end customers to increase the 943I :, B
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle CB *`
cost for battery storage in small stand alone photovoltaic systems. Also some basic /S7+B ]
environmental concerns are addressed. The report has been prepared under the supervision of [cG t
