The international Energy Agency (IEA) founded in November 1974, is an autonomous body z2lEHa?w
within the framework of the Organisation for Economic Co-operation and Development ( nH3
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 LMvsYc~]q
member countries. The European Commission also participates in the work of the Agency. = ,=t Sp
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 3;J)&(j0
agreements established within the IEA, and since 1993, its Participants have been conducting a G6b\4}E
variety of joint projects in the applications of Photovoltaic conversion of solar energy into w oqP&8a
electricity. 'j+J ?Y^
The Overall programme is headed by an Executive Committee composed of one representative :A{ US9D
from each participating country, while the management of individual research projects (Tasks) {s=$.Kg
is the responsibility of Operating Agents. Currently nine Tasks have been established in the =K)au$BE|
IEA PVPS programme. 4V`ypFme

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, H[{ch t
h
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV J 8"Cw<=O
systems will continue to represent a significant PV market segment, not only in developing e ga< {t
countries, but also in the important home markets of industrial countries. Experts from 15 IEA | '2E'?\/x
countries are sharing their experiences in this area. %HJ_0qg
This battery guide is intended for a wide use also close to the end customers to increase the :B<lDcFKJ
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle R9->.eE
cost for battery storage in small stand alone photovoltaic systems. Also some basic gn ?
