The international Energy Agency (IEA) founded in November 1974, is an autonomous body >o5eyi
within the framework of the Organisation for Economic Co-operation and Development \OV w
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 o?><(A|
member countries. The European Commission also participates in the work of the Agency. }*,z~y}V#
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D N{?Qkkgx
agreements established within the IEA, and since 1993, its Participants have been conducting a Tl pQ9T
variety of joint projects in the applications of Photovoltaic conversion of solar energy into b|u,[jEB
electricity. jBU !xCO
The Overall programme is headed by an Executive Committee composed of one representative I&>5b7Uf
from each participating country, while the management of individual research projects (Tasks) \:>eZl?
is the responsibility of Operating Agents. Currently nine Tasks have been established in the `o6T)49
IEA PVPS programme. B&?xq)%*#
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark 4 IXa[xAm
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), (``|5;T\

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, C8$/z>tQ
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV vg\fBHzn
systems will continue to represent a significant PV market segment, not only in developing 5](,N^u{):
countries, but also in the important home markets of industrial countries. Experts from 15 IEA # N'_~:H
countries are sharing their experiences in this area.

This battery guide is intended for a wide use also close to the end customers to increase the pXf5/u8&
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle QA #Jx
cost for battery storage in small stand alone photovoltaic systems. Also some basic :s# & nY
environmental concerns are addressed. The report has been prepared under the supervision of jN{+$ @cI
