The international Energy Agency (IEA) founded in November 1974, is an autonomous body V@>?lv(\
within the framework of the Organisation for Economic Co-operation and Development A&9l|b-"
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 D Ht 8 f
member countries. The European Commission also participates in the work of the Agency. [tMf KO
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D LEhku4U.
agreements established within the IEA, and since 1993, its Participants have been conducting a e+y< a~N
variety of joint projects in the applications of Photovoltaic conversion of solar energy into )[oU|!@
electricity. Ef,@}S
The Overall programme is headed by an Executive Committee composed of one representative @hzQk~Gdi
from each participating country, while the management of individual research projects (Tasks) xxkP4,(p
is the responsibility of Operating Agents. Currently nine Tasks have been established in the FZ=6x}QZ
IEA PVPS programme. ts;_ T..L

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, EE}NA{b
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV )lw7 W9
systems will continue to represent a significant PV market segment, not only in developing 4

countries, but also in the important home markets of industrial countries. Experts from 15 IEA lR.a3.~
countries are sharing their experiences in this area. Z$zUy |s[
This battery guide is intended for a wide use also close to the end customers to increase the iLmU|jdE
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle FG#j0#|*
cost for battery storage in small stand alone photovoltaic systems. Also some basic p~8~EQFj
environmental concerns are addressed. The report has been prepared under the supervision of u/.s rK!K
