Foreword q% pjY
The international Energy Agency (IEA) founded in November 1974, is an autonomous body WoSJp5By$
within the framework of the Organisation for Economic Co-operation and Development }'c@E0"
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 \!J9|
member countries. The European Commission also participates in the work of the Agency. o c0z1u
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 41s [p56+@
agreements established within the IEA, and since 1993, its Participants have been conducting a 7a#zr_ r
variety of joint projects in the applications of Photovoltaic conversion of solar energy into :yS Q[AJ"
electricity. N1l&$#Fr!s
The Overall programme is headed by an Executive Committee composed of one representative k 1sR^&{l
from each participating country, while the management of individual research projects (Tasks) I]jK]]@
is the responsibility of Operating Agents. Currently nine Tasks have been established in the < 1X Ja2
IEA PVPS programme. |$QL>{81

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ?YA5g' l
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV t=6Wk4
systems will continue to represent a significant PV market segment, not only in developing !vwx0
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 'boAv%1_sa
countries are sharing their experiences in this area. ]>" q>XgnI
This battery guide is intended for a wide use also close to the end customers to increase the \*x=q20
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle YA'_Ba(v)
cost for battery storage in small stand alone photovoltaic systems. Also some basic wJb"X=i*
environmental concerns are addressed. The report has been prepared under the supervision of .=% ,DT"
