The international Energy Agency (IEA) founded in November 1974, is an autonomous body _,w*Rv5 =
within the framework of the Organisation for Economic Co-operation and Development 7r pTk&`
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 :)Da^V
member countries. The European Commission also participates in the work of the Agency. Vc+~yh.)
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D E&Sr+D aPD
agreements established within the IEA, and since 1993, its Participants have been conducting a B0^:nYko
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ~O

electricity. TBgiA}|\D
The Overall programme is headed by an Executive Committee composed of one representative S}K-\[i?
from each participating country, while the management of individual research projects (Tasks) Az/P;C=
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ~ }Z {hs)
IEA PVPS programme. &+/$~@OK

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Ap kb!"}>
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV dCzS f4:
systems will continue to represent a significant PV market segment, not only in developing jjg&C9w T
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 111 9Y eL
countries are sharing their experiences in this area. K:Z|# i-
This battery guide is intended for a wide use also close to the end customers to increase the 6>h"Lsww
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle >j c17BJq
cost for battery storage in small stand alone photovoltaic systems. Also some basic O\ w-hk
environmental concerns are addressed. The report has been prepared under the supervision of d/E 0opv
