The international Energy Agency (IEA) founded in November 1974, is an autonomous body Ct =E;v7}
within the framework of the Organisation for Economic Co-operation and Development p z*/4
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 Jf %!I
member countries. The European Commission also participates in the work of the Agency. d vg;
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D p?Z+ z
agreements established within the IEA, and since 1993, its Participants have been conducting a ;w>3,ub(0
variety of joint projects in the applications of Photovoltaic conversion of solar energy into vxbH^b
electricity. |: 7EJkKZ
The Overall programme is headed by an Executive Committee composed of one representative -)y> c
from each participating country, while the management of individual research projects (Tasks) d U sJ v
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 5 p]urfN-f
IEA PVPS programme. X <ba| (

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, +YQ)}v
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV a>)_ `m
systems will continue to represent a significant PV market segment, not only in developing 8T>3@kF
countries, but also in the important home markets of industrial countries. Experts from 15 IEA S+_A
<p
countries are sharing their experiences in this area. X*0eN3o.
This battery guide is intended for a wide use also close to the end customers to increase the &;NNU T>Q
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle J]=aI>Ow
cost for battery storage in small stand alone photovoltaic systems. Also some basic D*d 3w
environmental concerns are addressed. The report has been prepared under the supervision of i
