The international Energy Agency (IEA) founded in November 1974, is an autonomous body V25u_R`{
within the framework of the Organisation for Economic Co-operation and Development ' uU{.bq
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 lbiMB~rwI
member countries. The European Commission also participates in the work of the Agency. qfsu# R
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D w}r~Wk^dLI
agreements established within the IEA, and since 1993, its Participants have been conducting a n0tVAH'>
variety of joint projects in the applications of Photovoltaic conversion of solar energy into A,]%*kg2
electricity. Z$: iq
The Overall programme is headed by an Executive Committee composed of one representative to# N>VfD
from each participating country, while the management of individual research projects (Tasks) A7=k 9|
is the responsibility of Operating Agents. Currently nine Tasks have been established in the (?lKedA>2
IEA PVPS programme. Vc$y ^|=
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark +'!Y[7|9iv
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), J:oAzBFpA

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, %3mh'Z -[f
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV *PF=dx<8
systems will continue to represent a significant PV market segment, not only in developing vw[i.af
countries, but also in the important home markets of industrial countries. Experts from 15 IEA POt 8G
countries are sharing their experiences in this area. ]Ofs, U^
This battery guide is intended for a wide use also close to the end customers to increase the Qs7*_=+h
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle B8.uzX'p
cost for battery storage in small stand alone photovoltaic systems. Also some basic mk]8}+^.
environmental concerns are addressed. The report has been prepared under the supervision of feG#*m2g
