Foreword WKek^TW4HE
The international Energy Agency (IEA) founded in November 1974, is an autonomous body EdR1W~JZ
within the framework of the Organisation for Economic Co-operation and Development z$C}V/Ey
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Z7)la
|
member countries. The European Commission also participates in the work of the Agency. -*HR0:H
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D N;gI %6
agreements established within the IEA, and since 1993, its Participants have been conducting a G*` Y~SJp
variety of joint projects in the applications of Photovoltaic conversion of solar energy into cHP~J%&L
electricity. gqw

The Overall programme is headed by an Executive Committee composed of one representative B*B}eXUph
from each participating country, while the management of individual research projects (Tasks) Vh=10Et
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ?o$ hlX
IEA PVPS programme. ,X^I]]

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 1!/WC.0
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV n;QMiz:yY
systems will continue to represent a significant PV market segment, not only in developing $1KvL 8
countries, but also in the important home markets of industrial countries. Experts from 15 IEA - aSj-
countries are sharing their experiences in this area. ol#|

This battery guide is intended for a wide use also close to the end customers to increase the /N=;3 yWF
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 3FetyW l'
cost for battery storage in small stand alone photovoltaic systems. Also some basic ;fi H=_{us
environmental concerns are addressed. The report has been prepared under the supervision of *UxN~?N|
