Foreword Z 2N6r6
The international Energy Agency (IEA) founded in November 1974, is an autonomous body gsbr8zwG,
within the framework of the Organisation for Economic Co-operation and Development In1W/ ?
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 @G" nkB
member countries. The European Commission also participates in the work of the Agency. ]p`y
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D :C*}Y g
agreements established within the IEA, and since 1993, its Participants have been conducting a L5bq\
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ,`}y J*7
electricity. a9-Mc5^'n
The Overall programme is headed by an Executive Committee composed of one representative @3.Z>KONx
from each participating country, while the management of individual research projects (Tasks) ^%$ Id Dx
is the responsibility of Operating Agents. Currently nine Tasks have been established in the k|/VNV( =0
IEA PVPS programme. Rn~'S2`u

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 8\rca:cF
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV "z{/*uM2<
systems will continue to represent a significant PV market segment, not only in developing Pvc)-A
countries, but also in the important home markets of industrial countries. Experts from 15 IEA J@2jx4
countries are sharing their experiences in this area. FOQ-KP\ =,
This battery guide is intended for a wide use also close to the end customers to increase the Wq A) V,E
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 3Y )&[aj
cost for battery storage in small stand alone photovoltaic systems. Also some basic rWTaCU^qV
environmental concerns are addressed. The report has been prepared under the supervision of h-96 2(LG
