Foreword w="
The international Energy Agency (IEA) founded in November 1974, is an autonomous body ()$tP3 o
within the framework of the Organisation for Economic Co-operation and Development Nrp1` qY
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 e=6C0fr
member countries. The European Commission also participates in the work of the Agency. }5gQ dj[Y
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ! "^//2N+,
agreements established within the IEA, and since 1993, its Participants have been conducting a g<4@5OQKu
variety of joint projects in the applications of Photovoltaic conversion of solar energy into {NIE:MXX
electricity. &ZP yZj
The Overall programme is headed by an Executive Committee composed of one representative ,|R\ Z,s
from each participating country, while the management of individual research projects (Tasks) -[lOf
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 5

IEA PVPS programme. E7Pz~6

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, OEgp!J
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV )6-!,D0 db
systems will continue to represent a significant PV market segment, not only in developing :'gX//b):
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ~LN
{5zg
countries are sharing their experiences in this area. uHO>FM,
This battery guide is intended for a wide use also close to the end customers to increase the 8DJoQl9
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle |NWo.j>4-
cost for battery storage in small stand alone photovoltaic systems. Also some basic jUX0sRDk
environmental concerns are addressed. The report has been prepared under the supervision of 7pz #%Hf
