The international Energy Agency (IEA) founded in November 1974, is an autonomous body X+<9 -]=
within the framework of the Organisation for Economic Co-operation and Development %e)vl[:}
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 A7&/3C6{H
member countries. The European Commission also participates in the work of the Agency. o4@d,uIw^
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Y C<FKWc
agreements established within the IEA, and since 1993, its Participants have been conducting a 2"j&_$#l5X
variety of joint projects in the applications of Photovoltaic conversion of solar energy into DMs8B&Y=
electricity. ^k{/Y l
The Overall programme is headed by an Executive Committee composed of one representative +lZ-xU1
from each participating country, while the management of individual research projects (Tasks) ,,6lQ]wG
is the responsibility of Operating Agents. Currently nine Tasks have been established in the VS>hi~j
IEA PVPS programme. {f*{dSm9 b

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, zf5%|7o
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV O U9{Y9e
systems will continue to represent a significant PV market segment, not only in developing yd'cLZd<}
countries, but also in the important home markets of industrial countries. Experts from 15 IEA /L 2n
~/
countries are sharing their experiences in this area. 1=E} X5
This battery guide is intended for a wide use also close to the end customers to increase the DYC2bs>
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle X7:Dw]t
cost for battery storage in small stand alone photovoltaic systems. Also some basic ,I+O;B:0
environmental concerns are addressed. The report has been prepared under the supervision of T nyLVIP
