The international Energy Agency (IEA) founded in November 1974, is an autonomous body %=t8
within the framework of the Organisation for Economic Co-operation and Development f kjo
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 sE Rm+x<
member countries. The European Commission also participates in the work of the Agency. ='"h B~[
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D JXa5snh{h
agreements established within the IEA, and since 1993, its Participants have been conducting a N)t qjq
variety of joint projects in the applications of Photovoltaic conversion of solar energy into (tLAJ_v!.K
electricity. U<"@@``+ N
The Overall programme is headed by an Executive Committee composed of one representative ( ;(DI^Un8
from each participating country, while the management of individual research projects (Tasks) 9R6]OL)p
is the responsibility of Operating Agents. Currently nine Tasks have been established in the F4xXJ"vc
IEA PVPS programme. $Z2Y% z6y

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, :Q@qR((&o
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV d2!A32m
systems will continue to represent a significant PV market segment, not only in developing c'gV
countries, but also in the important home markets of industrial countries. Experts from 15 IEA u} :p@j}Zv
countries are sharing their experiences in this area. TjswB#
This battery guide is intended for a wide use also close to the end customers to increase the nR2pqaKc
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle E/6@>.T?'
cost for battery storage in small stand alone photovoltaic systems. Also some basic *=p[;V
environmental concerns are addressed. The report has been prepared under the supervision of 'Rg6JW\
