The international Energy Agency (IEA) founded in November 1974, is an autonomous body P`V#Wj4\
within the framework of the Organisation for Economic Co-operation and Development 4i/ TEHQ
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ^[^u DE
<
member countries. The European Commission also participates in the work of the Agency. ]<++w;#+x
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D (_U&EX%
agreements established within the IEA, and since 1993, its Participants have been conducting a xJc'tT6@
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 4v E,nx=
electricity. ) 1 H]a'j
The Overall programme is headed by an Executive Committee composed of one representative (W*yF2r
from each participating country, while the management of individual research projects (Tasks) RFQa9Rxk
is the responsibility of Operating Agents. Currently nine Tasks have been established in the F4">go
IEA PVPS programme. Wm Od1

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, =We}&80 x
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV eT:%i "C
systems will continue to represent a significant PV market segment, not only in developing (w"zI!
countries, but also in the important home markets of industrial countries. Experts from 15 IEA D@O '8
countries are sharing their experiences in this area. ~mmI]

This battery guide is intended for a wide use also close to the end customers to increase the WpSdukXY{
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 36&7J{MU
cost for battery storage in small stand alone photovoltaic systems. Also some basic 7m@pdq5Ub
environmental concerns are addressed. The report has been prepared under the supervision of %# J8cB
