The international Energy Agency (IEA) founded in November 1974, is an autonomous body ,v"YqD+GC5
within the framework of the Organisation for Economic Co-operation and Development UFMA:o,
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 c/sC&i;%O
member countries. The European Commission also participates in the work of the Agency. X&kp;W
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Bve.C
agreements established within the IEA, and since 1993, its Participants have been conducting a .V,@k7U,V
variety of joint projects in the applications of Photovoltaic conversion of solar energy into :O uA)f
electricity. d3xmtG {i
The Overall programme is headed by an Executive Committee composed of one representative 4:FK;~wM&x
from each participating country, while the management of individual research projects (Tasks) #\=F O>
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ^0Mt*e{q
IEA PVPS programme. `nu''B

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 79;<_(Y
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV $&=S#_HQS
systems will continue to represent a significant PV market segment, not only in developing X(N LtO
w
countries, but also in the important home markets of industrial countries. Experts from 15 IEA \ kZ?
countries are sharing their experiences in this area. !z>6 Uf!{
This battery guide is intended for a wide use also close to the end customers to increase the *WuID2cOI
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle

cost for battery storage in small stand alone photovoltaic systems. Also some basic }~L.qG
environmental concerns are addressed. The report has been prepared under the supervision of x7Yu I
