Foreword A <iF37.
The international Energy Agency (IEA) founded in November 1974, is an autonomous body Rs)tf|`/
within the framework of the Organisation for Economic Co-operation and Development H;s0|KRgJ
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 G Q&9by=}
member countries. The European Commission also participates in the work of the Agency. )8&Q.? T
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D n4)G g~PE
agreements established within the IEA, and since 1993, its Participants have been conducting a yuswWc '
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 5L|yF"TI#
electricity. p< 'mc|hGq
The Overall programme is headed by an Executive Committee composed of one representative u7@|f ND 7
from each participating country, while the management of individual research projects (Tasks) ~/[cZY @
is the responsibility of Operating Agents. Currently nine Tasks have been established in the mT@UQCG
IEA PVPS programme. ezlp~z"_k

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, +d\ "n
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV $ sEe0
systems will continue to represent a significant PV market segment, not only in developing ZERUvk
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 9`.b
countries are sharing their experiences in this area. 65ijzZL;
This battery guide is intended for a wide use also close to the end customers to increase the 2DTH|Yv
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle m *P~X*St
cost for battery storage in small stand alone photovoltaic systems. Also some basic J~ v<Z/gm
environmental concerns are addressed. The report has been prepared under the supervision of ]*juF[r(
