The international Energy Agency (IEA) founded in November 1974, is an autonomous body }>m3V2>[
within the framework of the Organisation for Economic Co-operation and Development k6??+b:rE
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 1#jvr_ ga
member countries. The European Commission also participates in the work of the Agency. TmdR B8N
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D M5l*D'GE]
agreements established within the IEA, and since 1993, its Participants have been conducting a vA #?\j2
variety of joint projects in the applications of Photovoltaic conversion of solar energy into N0&#fXO
electricity. ) q'~<QxI\
The Overall programme is headed by an Executive Committee composed of one representative ;aUI3n%
from each participating country, while the management of individual research projects (Tasks) EhHW `
is the responsibility of Operating Agents. Currently nine Tasks have been established in the J!*Pg<
IEA PVPS programme. 4W+%`x_U]

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, eE[/#5tK
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV z, /y2H2
systems will continue to represent a significant PV market segment, not only in developing dIDs~
countries, but also in the important home markets of industrial countries. Experts from 15 IEA :Qklbd[9qF
countries are sharing their experiences in this area. s`"ALn8m
This battery guide is intended for a wide use also close to the end customers to increase the e 3 {L%rQE
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle von~-51;
cost for battery storage in small stand alone photovoltaic systems. Also some basic 4!tHJCq"
environmental concerns are addressed. The report has been prepared under the supervision of {>=#7e-]
