The international Energy Agency (IEA) founded in November 1974, is an autonomous body 4F{70"a
within the framework of the Organisation for Economic Co-operation and Development R47\Y
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 L+q/){Dd(
member countries. The European Commission also participates in the work of the Agency. yNbjoFM .i
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D q *9!,!e
agreements established within the IEA, and since 1993, its Participants have been conducting a -(=eM3o-9m
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 9B9(8PVG
electricity. j}C}:\-fY
The Overall programme is headed by an Executive Committee composed of one representative p } ~qf
from each participating country, while the management of individual research projects (Tasks) -j iG7OL
is the responsibility of Operating Agents. Currently nine Tasks have been established in the V=*w KuB
IEA PVPS programme. [)TRTxFb

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, c-0#w=
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV G2T|RT $_K
systems will continue to represent a significant PV market segment, not only in developing 5wDg'X]>V
countries, but also in the important home markets of industrial countries. Experts from 15 IEA K9up:.{QQ
countries are sharing their experiences in this area. 2_Z ? #Y
This battery guide is intended for a wide use also close to the end customers to increase the <Pi|J-Y
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle :w^Ed%>y7
cost for battery storage in small stand alone photovoltaic systems. Also some basic )z28=%g
environmental concerns are addressed. The report has been prepared under the supervision of m * kl
