The international Energy Agency (IEA) founded in November 1974, is an autonomous body &`qYe)1Eo
within the framework of the Organisation for Economic Co-operation and Development \s#~ %l
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 >2s 6Y
member countries. The European Commission also participates in the work of the Agency. -

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 7"Xy8]i{z
agreements established within the IEA, and since 1993, its Participants have been conducting a L~5f*LE$1
variety of joint projects in the applications of Photovoltaic conversion of solar energy into |X=p`iz1&
electricity.

The Overall programme is headed by an Executive Committee composed of one representative 9^!.!%6O$
from each participating country, while the management of individual research projects (Tasks) 9CS" s_
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 0Y e/
IEA PVPS programme. X}Q4;='C-

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, >IS4
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 1T#-1n%[k(
systems will continue to represent a significant PV market segment, not only in developing Ze%S<xT!O
countries, but also in the important home markets of industrial countries. Experts from 15 IEA FC+-|1?C
countries are sharing their experiences in this area. fcdX j_u
This battery guide is intended for a wide use also close to the end customers to increase the D N!V".m`J
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle qVh?%c1.Y
cost for battery storage in small stand alone photovoltaic systems. Also some basic ,C6(
environmental concerns are addressed. The report has been prepared under the supervision of i]< @
