Foreword I8c:U2D
The international Energy Agency (IEA) founded in November 1974, is an autonomous body PF#<CF$ =
within the framework of the Organisation for Economic Co-operation and Development 5z\,]
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 bdfs'udt9
member countries. The European Commission also participates in the work of the Agency. CIf@G>e-
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D $zF%F.rln
agreements established within the IEA, and since 1993, its Participants have been conducting a 8(\J~I[^
variety of joint projects in the applications of Photovoltaic conversion of solar energy into $$EEhy
electricity. w'XN<RWA
The Overall programme is headed by an Executive Committee composed of one representative gXU(0(Gq
from each participating country, while the management of individual research projects (Tasks) ><xmw=
is the responsibility of Operating Agents. Currently nine Tasks have been established in the qM6hE.J
IEA PVPS programme. Bs|Xq'1M!;
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark PKC0Dt;F.
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), *e<}hmDr

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, o7WAH@g
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV $ M/1pZ
systems will continue to represent a significant PV market segment, not only in developing +-9-%O.(;
countries, but also in the important home markets of industrial countries. Experts from 15 IEA k+*pg4'
countries are sharing their experiences in this area. +@yU `
This battery guide is intended for a wide use also close to the end customers to increase the !YI<A\P
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle iX<" \pV
cost for battery storage in small stand alone photovoltaic systems. Also some basic (h@!_qi9:
environmental concerns are addressed. The report has been prepared under the supervision of q2'}S
