Foreword o Z!1^o3V
The international Energy Agency (IEA) founded in November 1974, is an autonomous body CC~:z/4,N
within the framework of the Organisation for Economic Co-operation and Development m) - D rbE
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 5L!cS+QNU
member countries. The European Commission also participates in the work of the Agency. d siQ~ [
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D |GLh|hr
agreements established within the IEA, and since 1993, its Participants have been conducting a 2K~<_. S
variety of joint projects in the applications of Photovoltaic conversion of solar energy into li +MnL t
electricity. gd,3}@@SH
The Overall programme is headed by an Executive Committee composed of one representative *%#Sa~iPo
from each participating country, while the management of individual research projects (Tasks) <pXF$a:s
is the responsibility of Operating Agents. Currently nine Tasks have been established in the M#CYDEB
IEA PVPS programme. <j< V{Wc

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, "rJJ~[Y
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV c*~ /`lG
systems will continue to represent a significant PV market segment, not only in developing pFW^
countries, but also in the important home markets of industrial countries. Experts from 15 IEA (]}52%~
countries are sharing their experiences in this area. pOKs VS%fT
This battery guide is intended for a wide use also close to the end customers to increase the +bhR[V{0g
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle zcrM3`Zh
cost for battery storage in small stand alone photovoltaic systems. Also some basic iKVJ
