The international Energy Agency (IEA) founded in November 1974, is an autonomous body <NWq0 3:&
within the framework of the Organisation for Economic Co-operation and Development 5y8VA4L/o
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ]Bj2; <@y
member countries. The European Commission also participates in the work of the Agency. a'Yi^;2+\
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Q>(a JF
agreements established within the IEA, and since 1993, its Participants have been conducting a y #zO1Nig`
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 7!Qu+R
electricity. i93 6+[
The Overall programme is headed by an Executive Committee composed of one representative [h6 3* &
from each participating country, while the management of individual research projects (Tasks) /V
GI@"^v
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ?W2 u0N
IEA PVPS programme. %2y5a`b

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 10_# Z~aU
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 1Li*n6tLX`
systems will continue to represent a significant PV market segment, not only in developing $b(CN +#
countries, but also in the important home markets of industrial countries. Experts from 15 IEA y*%uGG5
countries are sharing their experiences in this area. Ad&VOh+0
This battery guide is intended for a wide use also close to the end customers to increase the !_P&SmK3
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle N "} N>xe2
cost for battery storage in small stand alone photovoltaic systems. Also some basic A `{hKS
environmental concerns are addressed. The report has been prepared under the supervision of -Xx4:S
