Foreword 4Z&lYLq;
The international Energy Agency (IEA) founded in November 1974, is an autonomous body |u<7?)mp
within the framework of the Organisation for Economic Co-operation and Development ^jZbo {
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 "ze|W\Bv!
member countries. The European Commission also participates in the work of the Agency. "<1{9
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D VlsnL8DV
agreements established within the IEA, and since 1993, its Participants have been conducting a #q=Efn'
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 0'C1YvF
electricity. Ve; n}mJ?
The Overall programme is headed by an Executive Committee composed of one representative ;4|15S
from each participating country, while the management of individual research projects (Tasks) q>+k@>bk @
is the responsibility of Operating Agents. Currently nine Tasks have been established in the V**~m9f
IEA PVPS programme. sDlO#

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, "+G8d' %YV
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV mCVFS=8V
systems will continue to represent a significant PV market segment, not only in developing rjYJs*#
countries, but also in the important home markets of industrial countries. Experts from 15 IEA oa p4rHk}
countries are sharing their experiences in this area. S.NPZ39}ZE
This battery guide is intended for a wide use also close to the end customers to increase the }K|oicpUg
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 3f{3NzN
cost for battery storage in small stand alone photovoltaic systems. Also some basic /a4{?? #e
environmental concerns are addressed. The report has been prepared under the supervision of 64tvP^kp
