The international Energy Agency (IEA) founded in November 1974, is an autonomous body }i._&x`):
within the framework of the Organisation for Economic Co-operation and Development <c3Te$.
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ij5|P4Eka
member countries. The European Commission also participates in the work of the Agency. Dr K@y8
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D CFXr=.yz
agreements established within the IEA, and since 1993, its Participants have been conducting a ;&c9! LfP
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Y6G`p
electricity. I

The Overall programme is headed by an Executive Committee composed of one representative Q@ua
G,6
from each participating country, while the management of individual research projects (Tasks) I9Lt> *
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 'pj*6t1~
IEA PVPS programme. @)XR

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, IFsh"i
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV W#&BU- |2
systems will continue to represent a significant PV market segment, not only in developing ',Y`\X
countries, but also in the important home markets of industrial countries. Experts from 15 IEA p~WX\;
countries are sharing their experiences in this area. !?)aZ |r
This battery guide is intended for a wide use also close to the end customers to increase the i^@hn>s$
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle *b7evU *1
cost for battery storage in small stand alone photovoltaic systems. Also some basic \NTVg6>qN
environmental concerns are addressed. The report has been prepared under the supervision of j-#h^3l1?
