The international Energy Agency (IEA) founded in November 1974, is an autonomous body 2QEH!)lvr
within the framework of the Organisation for Economic Co-operation and Development J7%rPJ
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 "L1LL
iS
member countries. The European Commission also participates in the work of the Agency. 3 |LRb/|
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D BY HyqpP9
agreements established within the IEA, and since 1993, its Participants have been conducting a T<b * =i
variety of joint projects in the applications of Photovoltaic conversion of solar energy into /0Qo (
electricity. OI78wG
The Overall programme is headed by an Executive Committee composed of one representative o"z;k3(i$7
from each participating country, while the management of individual research projects (Tasks) Qp) ?wny4
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ZWzr8oY)
IEA PVPS programme. {<gX~./]c
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark r!e W]M
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), I>vU;xV\m

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, U:eX^LE7
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 9(}d7y
systems will continue to represent a significant PV market segment, not only in developing .f. tPm
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ?"<m {,yQI
countries are sharing their experiences in this area. 9IrCu?n9b
This battery guide is intended for a wide use also close to the end customers to increase the gzH;`,
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle FwHqID_!:l
cost for battery storage in small stand alone photovoltaic systems. Also some basic ;mz#$"(
environmental concerns are addressed. The report has been prepared under the supervision of hNkv lk'Ui
