The international Energy Agency (IEA) founded in November 1974, is an autonomous body = ]7 \--
within the framework of the Organisation for Economic Co-operation and Development h ]MSjC.X
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 IP{Cj=
member countries. The European Commission also participates in the work of the Agency. dIM:U :c
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D #2cH.`ty
agreements established within the IEA, and since 1993, its Participants have been conducting a ^P{'l ^CVX
variety of joint projects in the applications of Photovoltaic conversion of solar energy into o8Bo %OjE
electricity. $F/&/Aa
The Overall programme is headed by an Executive Committee composed of one representative EDnmYaa)dZ
from each participating country, while the management of individual research projects (Tasks) ;g W~+hW ^
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ;7 IVg[f
IEA PVPS programme. $xloB
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark %lV>Nc|iz=
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), ]J htO{

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, &4{%3 w_/
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV A ;Zg:
systems will continue to represent a significant PV market segment, not only in developing x /9`2X`~
countries, but also in the important home markets of industrial countries. Experts from 15 IEA f_z2d+
countries are sharing their experiences in this area. =}Cb?C[;
This battery guide is intended for a wide use also close to the end customers to increase the RNi&OG(
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 59EAqz[:
cost for battery storage in small stand alone photovoltaic systems. Also some basic RmzK?muk
environmental concerns are addressed. The report has been prepared under the supervision of '{7A1yJnY%
