The international Energy Agency (IEA) founded in November 1974, is an autonomous body V/" 4 1
within the framework of the Organisation for Economic Co-operation and Development fG7 -0 7
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 F<6{$YI
member countries. The European Commission also participates in the work of the Agency. )4+uM'2%
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D r^\Wo7q
agreements established within the IEA, and since 1993, its Participants have been conducting a R?*-ZI[>w
variety of joint projects in the applications of Photovoltaic conversion of solar energy into B7'2@+(
electricity. :~ ,akX$
The Overall programme is headed by an Executive Committee composed of one representative 4T<d I6I0
from each participating country, while the management of individual research projects (Tasks) ~1{~i B2G
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 1T3YFt@&I
IEA PVPS programme. dp1t]

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, %A( hmC
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV yD ur9Qd6
systems will continue to represent a significant PV market segment, not only in developing *-_joAWTG
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 'V Y\ut
countries are sharing their experiences in this area. 4_Rv}Y d
This battery guide is intended for a wide use also close to the end customers to increase the a@gm r%C
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ;77q~_g$
cost for battery storage in small stand alone photovoltaic systems. Also some basic -| t|w:&
environmental concerns are addressed. The report has been prepared under the supervision of 3j$,x(ua9
