The international Energy Agency (IEA) founded in November 1974, is an autonomous body *,u3Wm|7
within the framework of the Organisation for Economic Co-operation and Development zLJ>)v$81
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 y<`5
member countries. The European Commission also participates in the work of the Agency. 1(' wg!
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D PgtLyzc
agreements established within the IEA, and since 1993, its Participants have been conducting a c~|(j \FI
variety of joint projects in the applications of Photovoltaic conversion of solar energy into [@$ SLl^Y
electricity. $<*) 5|6
The Overall programme is headed by an Executive Committee composed of one representative VZ]iep
from each participating country, while the management of individual research projects (Tasks) Z[O

is the responsibility of Operating Agents. Currently nine Tasks have been established in the HZrA}|:h
IEA PVPS programme. F`=p/IAJK

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, Y1r$;;sH
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV QE 4
systems will continue to represent a significant PV market segment, not only in developing 0nc(2Bi
countries, but also in the important home markets of industrial countries. Experts from 15 IEA E|pT6
countries are sharing their experiences in this area. T!/o^0w
This battery guide is intended for a wide use also close to the end customers to increase the A%w9Da?B
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle VuLb9Kn
cost for battery storage in small stand alone photovoltaic systems. Also some basic QO@86{u#Y
environmental concerns are addressed. The report has been prepared under the supervision of rfV'EjiM}
