The international Energy Agency (IEA) founded in November 1974, is an autonomous body MX]#|hEeQ
within the framework of the Organisation for Economic Co-operation and Development p^Ey6,!8]D
(OECD) which carries out a comprehensive programme of energy co-operation among its 23
|WaWmp(pQ
member countries. The European Commission also participates in the work of the Agency. >aJmRA-C}
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D O h
e^{:
agreements established within the IEA, and since 1993, its Participants have been conducting a "S#$:92
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ky|k g@n{
electricity. )vq}$W!:9
The Overall programme is headed by an Executive Committee composed of one representative

from each participating country, while the management of individual research projects (Tasks) eM!Oc$C8[
is the responsibility of Operating Agents. Currently nine Tasks have been established in the R>"pJbS;L
IEA PVPS programme. .*N,x(V

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ]A[}:E 5}
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV .~I:Hcf/
systems will continue to represent a significant PV market segment, not only in developing Srw`vql{(
countries, but also in the important home markets of industrial countries. Experts from 15 IEA cl`k d)"v
countries are sharing their experiences in this area. <!t;[ie?y
This battery guide is intended for a wide use also close to the end customers to increase the M5*Ln-qt(a
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle T ^eD
cost for battery storage in small stand alone photovoltaic systems. Also some basic S'RRe84 C
environmental concerns are addressed. The report has been prepared under the supervision of 15_"U+O(/
