The international Energy Agency (IEA) founded in November 1974, is an autonomous body .=7vI$ujd
within the framework of the Organisation for Economic Co-operation and Development TTX5EDCrC
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Q2 w_X8
member countries. The European Commission also participates in the work of the Agency. j ?3wvw6T
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D E1 aHKjLQ
agreements established within the IEA, and since 1993, its Participants have been conducting a *MFIV02[N
variety of joint projects in the applications of Photovoltaic conversion of solar energy into FBe;1OU
electricity. ]KKS"0a
The Overall programme is headed by an Executive Committee composed of one representative 5K1)1E/Fu
from each participating country, while the management of individual research projects (Tasks) B?gOHG*vd>
is the responsibility of Operating Agents. Currently nine Tasks have been established in the x*\Y)9Vgy
IEA PVPS programme. k<nZ+! M

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, d=$Mim
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ^qvZXb
systems will continue to represent a significant PV market segment, not only in developing T[w]o}>cW
countries, but also in the important home markets of industrial countries. Experts from 15 IEA XB;7!8|
countries are sharing their experiences in this area. ~f&E7su-6+
This battery guide is intended for a wide use also close to the end customers to increase the 1Z /(G1
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle J\} twYty
cost for battery storage in small stand alone photovoltaic systems. Also some basic ,B*EVN
environmental concerns are addressed. The report has been prepared under the supervision of gS!:+G%
