The international Energy Agency (IEA) founded in November 1974, is an autonomous body c$:=d4t5$
within the framework of the Organisation for Economic Co-operation and Development :gaeb8`t
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 [Ms{J!^q
member countries. The European Commission also participates in the work of the Agency. Ny7=-]N4{"
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D dS_)ll.6z
agreements established within the IEA, and since 1993, its Participants have been conducting a H6S v U
variety of joint projects in the applications of Photovoltaic conversion of solar energy into QN&^LaB<T
electricity. vP)~j1
The Overall programme is headed by an Executive Committee composed of one representative *Q 120 R
from each participating country, while the management of individual research projects (Tasks) 4?M3#],'h
is the responsibility of Operating Agents. Currently nine Tasks have been established in the :f Kz^@mY4
IEA PVPS programme. h]DE Cd{

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, $S GA60q
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV VD&3%G!
systems will continue to represent a significant PV market segment, not only in developing 't?7.#, 6O
countries, but also in the important home markets of industrial countries. Experts from 15 IEA !Fg4Au
countries are sharing their experiences in this area. [67E5rk-
This battery guide is intended for a wide use also close to the end customers to increase the |-Esc|J(
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle : tqm2t
cost for battery storage in small stand alone photovoltaic systems. Also some basic ^zPEAXm
environmental concerns are addressed. The report has been prepared under the supervision of ?r E]s!K
