The international Energy Agency (IEA) founded in November 1974, is an autonomous body AgUjC
within the framework of the Organisation for Economic Co-operation and Development #BZ5Mxzj
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 P*hYh5a
member countries. The European Commission also participates in the work of the Agency. .SSPJY(
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D .G"T;w 6d
agreements established within the IEA, and since 1993, its Participants have been conducting a oU*e=uehj
variety of joint projects in the applications of Photovoltaic conversion of solar energy into -Hy>

electricity. -Y N ( j \
The Overall programme is headed by an Executive Committee composed of one representative G %h+KTw
from each participating country, while the management of individual research projects (Tasks) uv{*f)j/d
is the responsibility of Operating Agents. Currently nine Tasks have been established in the r|/9'{!
IEA PVPS programme. h///

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, s9fEx -!y
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV [?g}<fa
systems will continue to represent a significant PV market segment, not only in developing 6Yqqq[#V/
countries, but also in the important home markets of industrial countries. Experts from 15 IEA !MmbwB'
countries are sharing their experiences in this area. fQ_tXY
This battery guide is intended for a wide use also close to the end customers to increase the PMvm4<
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle kY'C'9p
cost for battery storage in small stand alone photovoltaic systems. Also some basic OG q=OW
environmental concerns are addressed. The report has been prepared under the supervision of zW. Ltz
