The international Energy Agency (IEA) founded in November 1974, is an autonomous body \qB:z7I2
within the framework of the Organisation for Economic Co-operation and Development wrmbO T
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 >UDb:N[
member countries. The European Commission also participates in the work of the Agency. ,a1

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D (TQhO$,
agreements established within the IEA, and since 1993, its Participants have been conducting a y4Fuh nb>
variety of joint projects in the applications of Photovoltaic conversion of solar energy into *^_ywqp
electricity. |uRZT3bGyj
The Overall programme is headed by an Executive Committee composed of one representative * M,'F^E2
from each participating country, while the management of individual research projects (Tasks) DgB]y6~KXl
is the responsibility of Operating Agents. Currently nine Tasks have been established in the JC}oc M

IEA PVPS programme. oA'LQ
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark QGI_aU
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), 'X@>U6s

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, wdzZ41y1
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV i!k5P".o^
systems will continue to represent a significant PV market segment, not only in developing 01 ;
countries, but also in the important home markets of industrial countries. Experts from 15 IEA \~bx% VWW4
countries are sharing their experiences in this area. Pe<}kS

This battery guide is intended for a wide use also close to the end customers to increase the ^g eC?m
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle L4?)N&V
cost for battery storage in small stand alone photovoltaic systems. Also some basic uxsfQ%3`#
environmental concerns are addressed. The report has been prepared under the supervision of =n7 3bm
