The international Energy Agency (IEA) founded in November 1974, is an autonomous body y*5$B.u`.
within the framework of the Organisation for Economic Co-operation and Development c7/fQc)h4d
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 k4BiH5\hA
member countries. The European Commission also participates in the work of the Agency. d>jRw
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Y%YPR=j~ &
agreements established within the IEA, and since 1993, its Participants have been conducting a
%( o[H sl
variety of joint projects in the applications of Photovoltaic conversion of solar energy into Fhbp,CX4p
electricity. ?KXgG' !!
The Overall programme is headed by an Executive Committee composed of one representative 4e9'yi
from each participating country, while the management of individual research projects (Tasks) =y1/V'2E
is the responsibility of Operating Agents. Currently nine Tasks have been established in the M{M?#Q
IEA PVPS programme. tCbn B

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, JnBg;D|)@
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV

systems will continue to represent a significant PV market segment, not only in developing * 57y.](w
countries, but also in the important home markets of industrial countries. Experts from 15 IEA cT,5xp"a
countries are sharing their experiences in this area. pk2}]jx"
This battery guide is intended for a wide use also close to the end customers to increase the +}@6V4BRn
