Foreword HjG!pO{
The international Energy Agency (IEA) founded in November 1974, is an autonomous body mFoE2?Y
within the framework of the Organisation for Economic Co-operation and Development 3!]S8Y*LQP
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 24;F~y8H
member countries. The European Commission also participates in the work of the Agency. ;oL`fQyr
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D !e+ex"7
agreements established within the IEA, and since 1993, its Participants have been conducting a %-u Ra\
variety of joint projects in the applications of Photovoltaic conversion of solar energy into J~dk4D\
electricity. `yiw<9yp2
The Overall programme is headed by an Executive Committee composed of one representative gzdR|IBa
from each participating country, while the management of individual research projects (Tasks) yc ize2>q
is the responsibility of Operating Agents. Currently nine Tasks have been established in the Z*,Nt6;e
IEA PVPS programme. <<a1a

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, yMz%s=rh
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 0A$x'pU)
systems will continue to represent a significant PV market segment, not only in developing A}K2"lQ#>,
countries, but also in the important home markets of industrial countries. Experts from 15 IEA =Yd{PZ*fR
countries are sharing their experiences in this area. +-8S,Rg@
This battery guide is intended for a wide use also close to the end customers to increase the GJ1ap^k
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 6[cC1a3r:
cost for battery storage in small stand alone photovoltaic systems. Also some basic ~CTe5PX c
environmental concerns are addressed. The report has been prepared under the supervision of %OS}BAh^i
