The international Energy Agency (IEA) founded in November 1974, is an autonomous body 9 o6ig>C
within the framework of the Organisation for Economic Co-operation and Development I}Uj"m `>
(OECD) which carries out a comprehensive programme of energy co-operation among its 23
fy" q
member countries. The European Commission also participates in the work of the Agency. DZ -5A
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D X&fM36o 7
agreements established within the IEA, and since 1993, its Participants have been conducting a ms8de>A|H
variety of joint projects in the applications of Photovoltaic conversion of solar energy into yEyx.Mh.Af
electricity. ;rYL\`6L
The Overall programme is headed by an Executive Committee composed of one representative /"?yB$s
from each participating country, while the management of individual research projects (Tasks) +<7~yZ[Z8
is the responsibility of Operating Agents. Currently nine Tasks have been established in the u8L%R[#o
IEA PVPS programme. T Z{';o U

quality assurance and technical surveys on stand alone PV applications. Stand-alone PV =V~p QbZ
systems will continue to represent a significant PV market segment, not only in developing R hR{EO
countries, but also in the important home markets of industrial countries. Experts from 15 IEA >Lj0B%^EvM
countries are sharing their experiences in this area. _0dm?=
This battery guide is intended for a wide use also close to the end customers to increase the o0nd ]"q?
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle U Hh
cost for battery storage in small stand alone photovoltaic systems. Also some basic `~0)}K.F
