The international Energy Agency (IEA) founded in November 1974, is an autonomous body -= l m`X<:
within the framework of the Organisation for Economic Co-operation and Development `:lcN0n
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 B <s+I#
member countries. The European Commission also participates in the work of the Agency. lB27Z}
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Qb@j8Xa4[
agreements established within the IEA, and since 1993, its Participants have been conducting a ) , {3LIr
variety of joint projects in the applications of Photovoltaic conversion of solar energy into #N`'hPD}
electricity. @ fMlbJq
The Overall programme is headed by an Executive Committee composed of one representative 0c>>:w20D
from each participating country, while the management of individual research projects (Tasks) r^ "o!,H9q
is the responsibility of Operating Agents. Currently nine Tasks have been established in the b!g)/ %C
IEA PVPS programme. aKMX-?%t4

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, u|23M,
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV pJg:afCg
systems will continue to represent a significant PV market segment, not only in developing %;4#?.W8
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 26~rEOgJ
countries are sharing their experiences in this area. m:Rx<E

This battery guide is intended for a wide use also close to the end customers to increase the 08:K9zr
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle PE7V1U#$o,
cost for battery storage in small stand alone photovoltaic systems. Also some basic _$*-?*V&
environmental concerns are addressed. The report has been prepared under the supervision of jEKa9rt
