The international Energy Agency (IEA) founded in November 1974, is an autonomous body K]dX5vJw'
within the framework of the Organisation for Economic Co-operation and Development D }EH9d
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 StM)lVe F
member countries. The European Commission also participates in the work of the Agency. ?XO} 6q<tM
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D g<N3 L [
agreements established within the IEA, and since 1993, its Participants have been conducting a {m 5R=22^
variety of joint projects in the applications of Photovoltaic conversion of solar energy into b ;t b&o
electricity. ?1lx8+
The Overall programme is headed by an Executive Committee composed of one representative )\,hc$<= m
from each participating country, while the management of individual research projects (Tasks) r2>y

is the responsibility of Operating Agents. Currently nine Tasks have been established in the &6@e9ff0

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, s h^&3}
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV J|[`8 *8
systems will continue to represent a significant PV market segment, not only in developing Q4&<RWbT^
countries, but also in the important home markets of industrial countries. Experts from 15 IEA T|lyjX$Q]9
countries are sharing their experiences in this area. @)m+b;
This battery guide is intended for a wide use also close to the end customers to increase the /A/k13 J
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle %TRH,-@3h
cost for battery storage in small stand alone photovoltaic systems. Also some basic S]& 7
environmental concerns are addressed. The report has been prepared under the supervision of &|)
