The international Energy Agency (IEA) founded in November 1974, is an autonomous body olv0w ;s
within the framework of the Organisation for Economic Co-operation and Development G+~ f
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 OA7YWk<K
member countries. The European Commission also participates in the work of the Agency. Rs@>LA
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D wo+ b":
agreements established within the IEA, and since 1993, its Participants have been conducting a =?3b3PZn
variety of joint projects in the applications of Photovoltaic conversion of solar energy into T)Y{>wT
electricity. e S: 8Pn
The Overall programme is headed by an Executive Committee composed of one representative H 8 x66}
from each participating country, while the management of individual research projects (Tasks) .vnQZ*6
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ;;|o+4Ob;
IEA PVPS programme. ~dB x<

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, *t{^P*pc
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV [C#H _y(
systems will continue to represent a significant PV market segment, not only in developing XfQK
kol
countries, but also in the important home markets of industrial countries. Experts from 15 IEA oh0*b h
countries are sharing their experiences in this area. /:;"rnvq
This battery guide is intended for a wide use also close to the end customers to increase the aGAeRF
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ,<(0T$o E[
cost for battery storage in small stand alone photovoltaic systems. Also some basic @tIY%;Bgk
environmental concerns are addressed. The report has been prepared under the supervision of M Bqw{cy
