Foreword '3Q~y"C+4
The international Energy Agency (IEA) founded in November 1974, is an autonomous body C"B'Dj
within the framework of the Organisation for Economic Co-operation and Development }!R*Q`m
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @"1Z;.S8V
member countries. The European Commission also participates in the work of the Agency. u'Q82l&Y
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ,\c V,$
agreements established within the IEA, and since 1993, its Participants have been conducting a t[|t0y8
variety of joint projects in the applications of Photovoltaic conversion of solar energy into o3GkTn O
electricity. 19c_=$mV
The Overall programme is headed by an Executive Committee composed of one representative _aF8Us
from each participating country, while the management of individual research projects (Tasks) ir>h3Zk
is the responsibility of Operating Agents. Currently nine Tasks have been established in the N3aqNRwlk
IEA PVPS programme. x<Gjr}
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark .P/0`A{&

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, PREGQ0
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV [ }Tb2|
systems will continue to represent a significant PV market segment, not only in developing !<HMMf,-D
countries, but also in the important home markets of industrial countries. Experts from 15 IEA qe&B$3D|
countries are sharing their experiences in this area. q5= ,\S3=
This battery guide is intended for a wide use also close to the end customers to increase the (a8iCci:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle r|DIf28MIq
cost for battery storage in small stand alone photovoltaic systems. Also some basic SA&(%f1d
environmental concerns are addressed. The report has been prepared under the supervision of L6fbR-&Lt
