Foreword v[O?7Np
The international Energy Agency (IEA) founded in November 1974, is an autonomous body '~zi~Q7M
within the framework of the Organisation for Economic Co-operation and Development z-h?Q4;
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 /ACau<U]t
member countries. The European Commission also participates in the work of the Agency. ,>Dpt <
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D f9vit Fkb+
agreements established within the IEA, and since 1993, its Participants have been conducting a e'.CIspN
variety of joint projects in the applications of Photovoltaic conversion of solar energy into .TNGiUzG
electricity. y:Aha#<
The Overall programme is headed by an Executive Committee composed of one representative W#\{[o
from each participating country, while the management of individual research projects (Tasks) 9K- ,#a
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ZP

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, HQMug
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 3rX 40>Cs8
systems will continue to represent a significant PV market segment, not only in developing f6 s .xQ
countries, but also in the important home markets of industrial countries. Experts from 15 IEA nX8ulGG s
countries are sharing their experiences in this area. >96+s)T%;
This battery guide is intended for a wide use also close to the end customers to increase the ua,!kyS
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle PW\me7iCz
cost for battery storage in small stand alone photovoltaic systems. Also some basic 3Pvz5 7z{
environmental concerns are addressed. The report has been prepared under the supervision of M5 ^qc
