Foreword &(fB+VNrOH
The international Energy Agency (IEA) founded in November 1974, is an autonomous body /;M0tP
within the framework of the Organisation for Economic Co-operation and Development rO%
|PRP
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 //G5lW/*
member countries. The European Commission also participates in the work of the Agency. *M_.>".P
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D krTH<- P
agreements established within the IEA, and since 1993, its Participants have been conducting a _wWh7'u~G
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 4-`C !q
electricity. #,O<E@E
The Overall programme is headed by an Executive Committee composed of one representative 4q)eNcs
from each participating country, while the management of individual research projects (Tasks) W"fdK_F\
is the responsibility of Operating Agents. Currently nine Tasks have been established in the =KwG;25hX
IEA PVPS programme. +]Oq{v:e
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark H&65X
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), jNN$/ZWm

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, D"F5-s7
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV f/9]o
systems will continue to represent a significant PV market segment, not only in developing da3]#%i0
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Y%$57,Bu n
countries are sharing their experiences in this area. vJ$#m_aa
This battery guide is intended for a wide use also close to the end customers to increase the OGNjn9av
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 1Y410-.3w{
cost for battery storage in small stand alone photovoltaic systems. Also some basic x%ZjGDF m
environmental concerns are addressed. The report has been prepared under the supervision of /<Cl\q2
