Foreword c-M&cU+=L
The international Energy Agency (IEA) founded in November 1974, is an autonomous body q!O~*
within the framework of the Organisation for Economic Co-operation and Development 55,vmDd
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 EEkO[J[=
member countries. The European Commission also participates in the work of the Agency. -P.)

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D YVs{\1|'
agreements established within the IEA, and since 1993, its Participants have been conducting a J+ .t \ R
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 8, B9y D
electricity. 2<.}]yi
The Overall programme is headed by an Executive Committee composed of one representative uQ8]j .0
from each participating country, while the management of individual research projects (Tasks) F"0 tv$
is the responsibility of Operating Agents. Currently nine Tasks have been established in the SKcAZC
IEA PVPS programme. g|n P r)<

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 7L]fCw
p[
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV DtZkrj)D/
systems will continue to represent a significant PV market segment, not only in developing R0m}I5Frs
countries, but also in the important home markets of industrial countries. Experts from 15 IEA -MOf[f^
countries are sharing their experiences in this area. +'lfW{E1t
This battery guide is intended for a wide use also close to the end customers to increase the ueq R@i
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle P@*whjPmo
cost for battery storage in small stand alone photovoltaic systems. Also some basic vWj|[| <rX
environmental concerns are addressed. The report has been prepared under the supervision of QTP 1u
