The international Energy Agency (IEA) founded in November 1974, is an autonomous body boDt`2=
within the framework of the Organisation for Economic Co-operation and Development !K|5bK
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 jy-{~xdg[
member countries. The European Commission also participates in the work of the Agency. I? ,>DHUX
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D lNSLs"x ^
agreements established within the IEA, and since 1993, its Participants have been conducting a <&C]s b
variety of joint projects in the applications of Photovoltaic conversion of solar energy into e7wSOs
electricity. ZP{*.]Qu
The Overall programme is headed by an Executive Committee composed of one representative /?SLdW
from each participating country, while the management of individual research projects (Tasks) H;RwO@v
is the responsibility of Operating Agents. Currently nine Tasks have been established in the $ X q!L
IEA PVPS programme. |i++ 0BU

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Kr)a2rZ}SL
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV HTG%t/ S
systems will continue to represent a significant PV market segment, not only in developing 41&\mx
countries, but also in the important home markets of industrial countries. Experts from 15 IEA EFz&N\2
countries are sharing their experiences in this area. B_.%i+ZZ
This battery guide is intended for a wide use also close to the end customers to increase the ;+ "+3
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle % >=!p
cost for battery storage in small stand alone photovoltaic systems. Also some basic ]q4rlT.i
environmental concerns are addressed. The report has been prepared under the supervision of A0Qb 5e
