The international Energy Agency (IEA) founded in November 1974, is an autonomous body q=(M!9cE
within the framework of the Organisation for Economic Co-operation and Development `kI?Af*; v
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 )cf p(16
member countries. The European Commission also participates in the work of the Agency. |E>v~qD8I
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D UXXqE4x
agreements established within the IEA, and since 1993, its Participants have been conducting a vy>];!Cu
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ? Yynd
electricity. \3J+OY
The Overall programme is headed by an Executive Committee composed of one representative OLhWkN ,qA
from each participating country, while the management of individual research projects (Tasks) eA;j/&qH
is the responsibility of Operating Agents. Currently nine Tasks have been established in the g wZ+ GA
IEA PVPS programme. +Y_Q?/M@8

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, A= \'r<:
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV BV wRPt
systems will continue to represent a significant PV market segment, not only in developing Fj4l %=
countries, but also in the important home markets of industrial countries. Experts from 15 IEA nA{ncTg1\
countries are sharing their experiences in this area. >n@>h$]
This battery guide is intended for a wide use also close to the end customers to increase the WHdqO8
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle dK-
^
cost for battery storage in small stand alone photovoltaic systems. Also some basic dT*f-W
environmental concerns are addressed. The report has been prepared under the supervision of js %4;
