The international Energy Agency (IEA) founded in November 1974, is an autonomous body :u9OD` D
within the framework of the Organisation for Economic Co-operation and Development + e 87/\5
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 .}c&" L;W
member countries. The European Commission also participates in the work of the Agency. zCe [+F
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D E~y( @72)
agreements established within the IEA, and since 1993, its Participants have been conducting a (k^o[H F
variety of joint projects in the applications of Photovoltaic conversion of solar energy into N;q)[Dr
electricity. ;Zy[2M
The Overall programme is headed by an Executive Committee composed of one representative 11((b
from each participating country, while the management of individual research projects (Tasks) Due@ '
is the responsibility of Operating Agents. Currently nine Tasks have been established in the F +SqJSa
IEA PVPS programme. A`:a

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, #I"s{*
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV -hY@r 7y
systems will continue to represent a significant PV market segment, not only in developing X5tx(}j
countries, but also in the important home markets of industrial countries. Experts from 15 IEA
'N3)>!Y:8
countries are sharing their experiences in this area. SaIY-PC
This battery guide is intended for a wide use also close to the end customers to increase the |JLX gwML
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle q|g>; _
cost for battery storage in small stand alone photovoltaic systems. Also some basic x^7 9s_h5
environmental concerns are addressed. The report has been prepared under the supervision of {[)n<.n[g
