Foreword mzw*6e2T
The international Energy Agency (IEA) founded in November 1974, is an autonomous body c"$_V[m
within the framework of the Organisation for Economic Co-operation and Development %51pf u L
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ' FK" -)s
member countries. The European Commission also participates in the work of the Agency. > @%!r
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D (j /O=$mJ
agreements established within the IEA, and since 1993, its Participants have been conducting a W!(Q_B
variety of joint projects in the applications of Photovoltaic conversion of solar energy into BY d3 rI
electricity. ,@;<u'1\G
The Overall programme is headed by an Executive Committee composed of one representative {h=Ai[|l4Q
from each participating country, while the management of individual research projects (Tasks) CP'-CQ\Q
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ?`XKaD!

IEA PVPS programme. :

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, l rzW H0Q
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV z yr6Tv61U
systems will continue to represent a significant PV market segment, not only in developing ]3C8
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 5-*]PAC
countries are sharing their experiences in this area. Xy{+=UY
This battery guide is intended for a wide use also close to the end customers to increase the * y B-N;I
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ^bG!k]U!2
cost for battery storage in small stand alone photovoltaic systems. Also some basic p1nA7;B-m
environmental concerns are addressed. The report has been prepared under the supervision of SD&[K
