The international Energy Agency (IEA) founded in November 1974, is an autonomous body eUPG) { "
within the framework of the Organisation for Economic Co-operation and Development zuUf:%k}I
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 "5C)gxI^
member countries. The European Commission also participates in the work of the Agency. LbOjKM^-
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D X&nkc/erx
agreements established within the IEA, and since 1993, its Participants have been conducting a <&\HXAOd
variety of joint projects in the applications of Photovoltaic conversion of solar energy into -U)6o"O_CV
electricity. zB/$*Hd
The Overall programme is headed by an Executive Committee composed of one representative "(5A 5>
from each participating country, while the management of individual research projects (Tasks) fqZqPcT0
is the responsibility of Operating Agents. Currently nine Tasks have been established in the #q Wa[kB
IEA PVPS programme. fp|!LU

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Q<B=m6~
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV |(N4ZmTm
systems will continue to represent a significant PV market segment, not only in developing QE [ETv
countries, but also in the important home markets of industrial countries. Experts from 15 IEA
YqX/7b+
countries are sharing their experiences in this area. tX$%*Uy
This battery guide is intended for a wide use also close to the end customers to increase the P0uUVU=B|
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ,pE{N&p9
cost for battery storage in small stand alone photovoltaic systems. Also some basic " NnUu 8x
environmental concerns are addressed. The report has been prepared under the supervision of li;Np5P
