Foreword q2M %AvR
The international Energy Agency (IEA) founded in November 1974, is an autonomous body ppO!v?
within the framework of the Organisation for Economic Co-operation and Development 4hUUQ;x j
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 A \Z _br
member countries. The European Commission also participates in the work of the Agency. fg

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D > Qh#pn*
agreements established within the IEA, and since 1993, its Participants have been conducting a ~:-V<r,pe
variety of joint projects in the applications of Photovoltaic conversion of solar energy into iF1zLI<A
electricity. IOl0=+p
The Overall programme is headed by an Executive Committee composed of one representative A$TF a:O|
from each participating country, while the management of individual research projects (Tasks) <p[RhP
is the responsibility of Operating Agents. Currently nine Tasks have been established in the @! jpJ}
IEA PVPS programme. D~,i I7ac
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark +sXnC\
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), B:)vPO + d

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, x ^
sTGd
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 3.%jet1
systems will continue to represent a significant PV market segment, not only in developing ~P9 ^4
countries, but also in the important home markets of industrial countries. Experts from 15 IEA bbWW|PtWwP
countries are sharing their experiences in this area. &9xcP.3
This battery guide is intended for a wide use also close to the end customers to increase the EHt(! ;?q
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle X{qa|6S,F
cost for battery storage in small stand alone photovoltaic systems. Also some basic _61tE
environmental concerns are addressed. The report has been prepared under the supervision of X&,a=#C^
