The international Energy Agency (IEA) founded in November 1974, is an autonomous body `V9bd}M%~;
within the framework of the Organisation for Economic Co-operation and Development +ZbNSN=
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 WSMpX -^e@
member countries. The European Commission also participates in the work of the Agency. +c /!R|h=S

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, E{[Y8U1n
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ,y'6vW`%g9
systems will continue to represent a significant PV market segment, not only in developing

countries, but also in the important home markets of industrial countries. Experts from 15 IEA gs!'*U )
countries are sharing their experiences in this area. DTH }= r-
This battery guide is intended for a wide use also close to the end customers to increase the a& 0g0n6
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle W0MgY%Qv[
