The international Energy Agency (IEA) founded in November 1974, is an autonomous body ^>R| R1&
within the framework of the Organisation for Economic Co-operation and Development f6_|dvY3
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 MFdFZkpiV
member countries. The European Commission also participates in the work of the Agency. [@l

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Qmc; s{-r;
agreements established within the IEA, and since 1993, its Participants have been conducting a R 7;rBEt8
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 3b[[2x_UU
electricity. $E@.G1T [
The Overall programme is headed by an Executive Committee composed of one representative DSG +TA"
from each participating country, while the management of individual research projects (Tasks) 6Bq2?;5
is the responsibility of Operating Agents. Currently nine Tasks have been established in the #/sE{jm
IEA PVPS programme. [Jh))DIx

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ,["|wqM
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV cS ;=_%~
systems will continue to represent a significant PV market segment, not only in developing ' ^L
countries, but also in the important home markets of industrial countries. Experts from 15 IEA D30Z9_^%:
countries are sharing their experiences in this area. u9~V2>r\
This battery guide is intended for a wide use also close to the end customers to increase the U!UX"r
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle Q \>SF
cost for battery storage in small stand alone photovoltaic systems. Also some basic xA1pDrfC/
environmental concerns are addressed. The report has been prepared under the supervision of DBrzw+;e3
