The international Energy Agency (IEA) founded in November 1974, is an autonomous body l r~ >!O
within the framework of the Organisation for Economic Co-operation and Development $fPiR
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 <I?f=[
member countries. The European Commission also participates in the work of the Agency. . 7Pp'-hK
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D w8KxEV=
agreements established within the IEA, and since 1993, its Participants have been conducting a pJo4&Ff
variety of joint projects in the applications of Photovoltaic conversion of solar energy into or)fx/ %h
electricity. ?H{?jJj$H
The Overall programme is headed by an Executive Committee composed of one representative 0G'v4Vj0'
from each participating country, while the management of individual research projects (Tasks) ]N 1,"W}
is the responsibility of Operating Agents. Currently nine Tasks have been established in the wSALK)T1{
IEA PVPS programme. QdD @[

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, !l9 #a{#6l
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV I'<sJs*p
systems will continue to represent a significant PV market segment, not only in developing xKT;1 (Mk
countries, but also in the important home markets of industrial countries. Experts from 15 IEA k?Zcv*[)D+
countries are sharing their experiences in this area. =wl0
This battery guide is intended for a wide use also close to the end customers to increase the $ Fy)+<
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle pC&i!la{o}
cost for battery storage in small stand alone photovoltaic systems. Also some basic 7i=ER*F~
environmental concerns are addressed. The report has been prepared under the supervision of u b@'(*
