Foreword I<Wp, E9G#
The international Energy Agency (IEA) founded in November 1974, is an autonomous body N2#Wyt8MC
within the framework of the Organisation for Economic Co-operation and Development *c3(,Bm w
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 6j/g/!9c!
member countries. The European Commission also participates in the work of the Agency. =^\yE"a
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D db -h=L|
agreements established within the IEA, and since 1993, its Participants have been conducting a hSr2<?yk
variety of joint projects in the applications of Photovoltaic conversion of solar energy into G)t_;iNL|
electricity. ,1&Pb %}
The Overall programme is headed by an Executive Committee composed of one representative L 7VD ZCV
from each participating country, while the management of individual research projects (Tasks) q !iS Y
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Vsw] v
IEA PVPS programme. ]{ ^'{ z$i

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, w`KqB(36
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 4&N#d;ErC
systems will continue to represent a significant PV market segment, not only in developing PDQEI55
countries, but also in the important home markets of industrial countries. Experts from 15 IEA kD;1+l Nz
countries are sharing their experiences in this area. Bie#GKc
This battery guide is intended for a wide use also close to the end customers to increase the H{ M7_1T
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 1*U)\vK~
cost for battery storage in small stand alone photovoltaic systems. Also some basic >-oB%T
environmental concerns are addressed. The report has been prepared under the supervision of x$hh H=
