The international Energy Agency (IEA) founded in November 1974, is an autonomous body z\eQB% aM
within the framework of the Organisation for Economic Co-operation and Development DQ8/]Z{H
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 )5@P|{FF
member countries. The European Commission also participates in the work of the Agency. ovp/D M
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D k@7# 8(3
agreements established within the IEA, and since 1993, its Participants have been conducting a $ 6n

variety of joint projects in the applications of Photovoltaic conversion of solar energy into X 2V+cre
electricity. O\Huj=
The Overall programme is headed by an Executive Committee composed of one representative 'u.Dt*.Uq
from each participating country, while the management of individual research projects (Tasks) OP\jO DX
is the responsibility of Operating Agents. Currently nine Tasks have been established in the :|(YlNUv
IEA PVPS programme. N k@-yZ@,8

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, +2{ f>KZ
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 6c!F%xU}
systems will continue to represent a significant PV market segment, not only in developing }aOqoi7w
countries, but also in the important home markets of industrial countries. Experts from 15 IEA F`4W5~`
countries are sharing their experiences in this area. p*PzfSLN
This battery guide is intended for a wide use also close to the end customers to increase the bf/6AY7
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle h r]+ 4!/
cost for battery storage in small stand alone photovoltaic systems. Also some basic lZAGoR;0Ra
environmental concerns are addressed. The report has been prepared under the supervision of ] !*K|?VL
