Foreword xLIyh7$t
The international Energy Agency (IEA) founded in November 1974, is an autonomous body .:H'9QJg
within the framework of the Organisation for Economic Co-operation and Development tgBA(2/Co
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ~^.,Ftkb@7
member countries. The European Commission also participates in the work of the Agency. s;h `n$
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D :C;fEJN
agreements established within the IEA, and since 1993, its Participants have been conducting a ^Whc<>|
variety of joint projects in the applications of Photovoltaic conversion of solar energy into K/( LF}
electricity. +PYR
The Overall programme is headed by an Executive Committee composed of one representative "^t7]=q
from each participating country, while the management of individual research projects (Tasks) gs2qLb
is the responsibility of Operating Agents. Currently nine Tasks have been established in the <=uO*s>%
IEA PVPS programme. S ?t

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, w 8o?wx*
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV zX=%BL?
systems will continue to represent a significant PV market segment, not only in developing &>B|?d
countries, but also in the important home markets of industrial countries. Experts from 15 IEA @lB1t=
D
countries are sharing their experiences in this area. >pt I!\ i}
This battery guide is intended for a wide use also close to the end customers to increase the ,S(_YS^m
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle :%Z)u:~':
cost for battery storage in small stand alone photovoltaic systems. Also some basic .WOF:Nu4
environmental concerns are addressed. The report has been prepared under the supervision of MS SHMR
