Foreword Wdt9k.hzN
The international Energy Agency (IEA) founded in November 1974, is an autonomous body <&7KcvBn"4
within the framework of the Organisation for Economic Co-operation and Development cT8`l!RD<
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 _)J;PbK~
member countries. The European Commission also participates in the work of the Agency. KfU4#2}
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D FtUO gL)|
agreements established within the IEA, and since 1993, its Participants have been conducting a dQ=mg#(
variety of joint projects in the applications of Photovoltaic conversion of solar energy into k, L ,
electricity. avR4 #bfc
The Overall programme is headed by an Executive Committee composed of one representative C+r<DC3
from each participating country, while the management of individual research projects (Tasks) f`5e0;zm
is the responsibility of Operating Agents. Currently nine Tasks have been established in the :*bmc /c
IEA PVPS programme. /t-m/&>

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ta>:iQ a
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 8K!

systems will continue to represent a significant PV market segment, not only in developing d}K"dr:W5
countries, but also in the important home markets of industrial countries. Experts from 15 IEA DiK@> $v
countries are sharing their experiences in this area. r\y~

This battery guide is intended for a wide use also close to the end customers to increase the |x| #n
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle vUGEzC M
cost for battery storage in small stand alone photovoltaic systems. Also some basic 3~"G(UP
environmental concerns are addressed. The report has been prepared under the supervision of r5qp[Ss3F
