The international Energy Agency (IEA) founded in November 1974, is an autonomous body +nJgl8'^y
within the framework of the Organisation for Economic Co-operation and Development e?8HgiP-
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 4b98Ks Yg
member countries. The European Commission also participates in the work of the Agency. 6">+

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ;wz^gd h;
agreements established within the IEA, and since 1993, its Participants have been conducting a }&w Ur>=
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ,F,X

The Overall programme is headed by an Executive Committee composed of one representative AP'*Nh@Ik(
from each participating country, while the management of individual research projects (Tasks) R#%(5-Zu#R
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 7/I, HxXp!
IEA PVPS programme. i OW#>66d

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, t /VD31
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV : y%d
systems will continue to represent a significant PV market segment, not only in developing ,( EO'T[
countries, but also in the important home markets of industrial countries. Experts from 15 IEA n*[XR`r}
countries are sharing their experiences in this area. DtXrWS/
This battery guide is intended for a wide use also close to the end customers to increase the |)(VsVG&
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle u{ ['<r ;I
cost for battery storage in small stand alone photovoltaic systems. Also some basic 1g8_Xe4
environmental concerns are addressed. The report has been prepared under the supervision of UC]\yUK1J
