The international Energy Agency (IEA) founded in November 1974, is an autonomous body GK$[ !{w;
within the framework of the Organisation for Economic Co-operation and Development jR%*,IeB
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 |nNcV~%~
member countries. The European Commission also participates in the work of the Agency. bWTf P8gT
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D sh
:$J[
agreements established within the IEA, and since 1993, its Participants have been conducting a /h >g-zb
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ZDW9H6ux
electricity. i(4<MB1a
The Overall programme is headed by an Executive Committee composed of one representative !Se0&Ob
from each participating country, while the management of individual research projects (Tasks) 1'&.6{)P
is the responsibility of Operating Agents. Currently nine Tasks have been established in the IR-n: z
IEA PVPS programme. JLu$1A@ '

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 0GUJc}fgvN
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ~e}JqJ(97
systems will continue to represent a significant PV market segment, not only in developing n{gEIUo#
countries, but also in the important home markets of industrial countries. Experts from 15 IEA {w2]
Is2F
countries are sharing their experiences in this area. 3L &:
This battery guide is intended for a wide use also close to the end customers to increase the mi=mwN%UB
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Jxvh;
cost for battery storage in small stand alone photovoltaic systems. Also some basic ||:> &
environmental concerns are addressed. The report has been prepared under the supervision of >eTbg"\
