The international Energy Agency (IEA) founded in November 1974, is an autonomous body b U ]N^og^
within the framework of the Organisation for Economic Co-operation and Development lmKq xs4
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 U!:!]DX(
member countries. The European Commission also participates in the work of the Agency. MuV0;K \
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Ok~{@\
agreements established within the IEA, and since 1993, its Participants have been conducting a !`[I>:Ex
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ""3m!qn#
electricity. ~88 Tz+
The Overall programme is headed by an Executive Committee composed of one representative 9}cuAVI
from each participating country, while the management of individual research projects (Tasks) sLdUrD%
is the responsibility of Operating Agents. Currently nine Tasks have been established in the t *

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, QYfAf3te
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV n X\]i~
systems will continue to represent a significant PV market segment, not only in developing S~Iw?SK3
countries, but also in the important home markets of industrial countries. Experts from 15 IEA %;(|KrUN
countries are sharing their experiences in this area. LQ\

This battery guide is intended for a wide use also close to the end customers to increase the *C@[5#CA2z
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle }&T<wm !
cost for battery storage in small stand alone photovoltaic systems. Also some basic (1AA;)`Kp
environmental concerns are addressed. The report has been prepared under the supervision of .(7C)P{ .0
