Foreword ?;s}GpEY:
The international Energy Agency (IEA) founded in November 1974, is an autonomous body i+x$Y)=
within the framework of the Organisation for Economic Co-operation and Development O5:?nD
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 [0M2`x4`
member countries. The European Commission also participates in the work of the Agency. ,G";ny [$
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 5 XK}8\
agreements established within the IEA, and since 1993, its Participants have been conducting a CdxEY
variety of joint projects in the applications of Photovoltaic conversion of solar energy into "pP5;*^f
electricity. !H,_*u.
The Overall programme is headed by an Executive Committee composed of one representative T =/GF g'
from each participating country, while the management of individual research projects (Tasks) YL(7l|^!
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 2E

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, f s8nYgv|Q
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV _R&}CP
systems will continue to represent a significant PV market segment, not only in developing x$G u)S
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ]:lqbg[J
countries are sharing their experiences in this area. mcbr3P
This battery guide is intended for a wide use also close to the end customers to increase the K k 5 vC{
