The international Energy Agency (IEA) founded in November 1974, is an autonomous body Elb aFbr
within the framework of the Organisation for Economic Co-operation and Development fThgK;Qy'U
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 g`0mo Xz
member countries. The European Commission also participates in the work of the Agency. qf#)lyr<D6
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D o6a0'vU><
agreements established within the IEA, and since 1993, its Participants have been conducting a ]s_8A`v m
variety of joint projects in the applications of Photovoltaic conversion of solar energy into pHC /(6?
electricity. Da.G4,vLh
The Overall programme is headed by an Executive Committee composed of one representative Q.Aa{d9e
from each participating country, while the management of individual research projects (Tasks) )nfEQ)L;h}
is the responsibility of Operating Agents. Currently nine Tasks have been established in the mJ5H=&Z
IEA PVPS programme. *

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ,Nm$i"Lg
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ;9a 6pz<
systems will continue to represent a significant PV market segment, not only in developing I&VTW8jB
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 5B4Ssrs5W~
countries are sharing their experiences in this area. L] %l51U
This battery guide is intended for a wide use also close to the end customers to increase the b:W-l?
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle xHA0gZf
cost for battery storage in small stand alone photovoltaic systems. Also some basic 6 %Mt
environmental concerns are addressed. The report has been prepared under the supervision of r!
