The international Energy Agency (IEA) founded in November 1974, is an autonomous body T 1R~^x1
within the framework of the Organisation for Economic Co-operation and Development j9yOkaVEg
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 NEPK
member countries. The European Commission also participates in the work of the Agency. Z "qJil}
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D bg /=P>2
agreements established within the IEA, and since 1993, its Participants have been conducting a $|7=$~y
variety of joint projects in the applications of Photovoltaic conversion of solar energy into KJv%t_4'F
electricity. gK( G1
The Overall programme is headed by an Executive Committee composed of one representative ! * KQ2#e
from each participating country, while the management of individual research projects (Tasks) : >Bk^"
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 4q:8<*W=
IEA PVPS programme. 9H PmJ`b

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, [La}h2gz
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV US=K}B =g
systems will continue to represent a significant PV market segment, not only in developing .t8hTlV?<B
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ~ ^D2]j
countries are sharing their experiences in this area. 6k![v@2R
This battery guide is intended for a wide use also close to the end customers to increase the Gy;Fe=
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle w c~s:
cost for battery storage in small stand alone photovoltaic systems. Also some basic s$, G5Feub
environmental concerns are addressed. The report has been prepared under the supervision of e igVT4
