Foreword U^-J _ yq
The international Energy Agency (IEA) founded in November 1974, is an autonomous body _nw\ac#*
within the framework of the Organisation for Economic Co-operation and Development $D f1t
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 JKCV >k
member countries. The European Commission also participates in the work of the Agency. Kj6+$l
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ypfjF@OT
agreements established within the IEA, and since 1993, its Participants have been conducting a *t={9 h
variety of joint projects in the applications of Photovoltaic conversion of solar energy into _F8-4
electricity. Rob: W|
The Overall programme is headed by an Executive Committee composed of one representative qrt2uE{K
from each participating country, while the management of individual research projects (Tasks) `0{qfms
is the responsibility of Operating Agents. Currently nine Tasks have been established in the o
i~,}E_
IEA PVPS programme. 5=4-IO6W[]

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, vha@YPC=
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV lPl JL`e
systems will continue to represent a significant PV market segment, not only in developing Yt4v}{+
countries, but also in the important home markets of industrial countries. Experts from 15 IEA >>=v `}
countries are sharing their experiences in this area. E

This battery guide is intended for a wide use also close to the end customers to increase the b1ZHfe:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle _ `7[}M~
cost for battery storage in small stand alone photovoltaic systems. Also some basic OQT i$2
environmental concerns are addressed. The report has been prepared under the supervision of 2L 1Azx
