Foreword \4O_@d`A
The international Energy Agency (IEA) founded in November 1974, is an autonomous body v]}\Ns/
within the framework of the Organisation for Economic Co-operation and Development nW
oh( a
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 zu
7Fq ]zD
member countries. The European Commission also participates in the work of the Agency. a.a

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D D J7U6{KLq
agreements established within the IEA, and since 1993, its Participants have been conducting a T`GiM%R;g
variety of joint projects in the applications of Photovoltaic conversion of solar energy into y<c7 RK]
electricity. gSe3S-Lt
The Overall programme is headed by an Executive Committee composed of one representative WYIv&h <h"
from each participating country, while the management of individual research projects (Tasks) K{ntl-D&y
is the responsibility of Operating Agents. Currently nine Tasks have been established in the k:N/-P&+
IEA PVPS programme. T9Fe!yVA

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, U.Y7]#P:
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ]Qe"S>,?`
systems will continue to represent a significant PV market segment, not only in developing xtK\-[n
countries, but also in the important home markets of industrial countries. Experts from 15 IEA p =-~qBw
countries are sharing their experiences in this area. w: mm@8N
This battery guide is intended for a wide use also close to the end customers to increase the F^5\w-gLY
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle hoLA *v2<
cost for battery storage in small stand alone photovoltaic systems. Also some basic )_6W@s
environmental concerns are addressed. The report has been prepared under the supervision of [GcW *v
