The international Energy Agency (IEA) founded in November 1974, is an autonomous body ozbu|9 +v
within the framework of the Organisation for Economic Co-operation and Development }F1|&
A
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 AopC xaJ`
member countries. The European Commission also participates in the work of the Agency. H|H!VPof]
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D I"^ `!8<q
agreements established within the IEA, and since 1993, its Participants have been conducting a PYl(~Vac
variety of joint projects in the applications of Photovoltaic conversion of solar energy into [e+"G <>
electricity. ~bCn%r2
The Overall programme is headed by an Executive Committee composed of one representative Y

from each participating country, while the management of individual research projects (Tasks) 37 wm[ Z
is the responsibility of Operating Agents. Currently nine Tasks have been established in the A|V

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, @O<kjR<b
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV s Y=fS2b#)
systems will continue to represent a significant PV market segment, not only in developing
f$mfY6v
countries, but also in the important home markets of industrial countries. Experts from 15 IEA C

countries are sharing their experiences in this area. 1q*85 [Y
This battery guide is intended for a wide use also close to the end customers to increase the 0sq1SH I{
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ` RUr/|S
cost for battery storage in small stand alone photovoltaic systems. Also some basic W
