The international Energy Agency (IEA) founded in November 1974, is an autonomous body Oet+$ b
within the framework of the Organisation for Economic Co-operation and Development vQ]d?Tp
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 x NjQ"'i8
member countries. The European Commission also participates in the work of the Agency. shw"TF>?zG
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D $8 x b|S[
agreements established within the IEA, and since 1993, its Participants have been conducting a jJ-C\
v
variety of joint projects in the applications of Photovoltaic conversion of solar energy into PR]b ]=
electricity. )$1>6C \
The Overall programme is headed by an Executive Committee composed of one representative C <3<,~gI
from each participating country, while the management of individual research projects (Tasks) k}p8"'O
is the responsibility of Operating Agents. Currently nine Tasks have been established in the s2<[@@@q
IEA PVPS programme. L~^5Ez6U

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, @"MQ6u G>
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ]ly" K!1,
systems will continue to represent a significant PV market segment, not only in developing ^!d0a bA
countries, but also in the important home markets of industrial countries. Experts from 15 IEA aWlIq(dU
countries are sharing their experiences in this area. atF#0*e>
This battery guide is intended for a wide use also close to the end customers to increase the 3fp&iz
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle od a,
cost for battery storage in small stand alone photovoltaic systems. Also some basic aZCq{7Xs
environmental concerns are addressed. The report has been prepared under the supervision of '5 ~cd
