The international Energy Agency (IEA) founded in November 1974, is an autonomous body xb`CdtG2.
within the framework of the Organisation for Economic Co-operation and Development uV77E*+7\
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 5"gL.Ez
member countries. The European Commission also participates in the work of the Agency. }

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D e5OVq
,
agreements established within the IEA, and since 1993, its Participants have been conducting a FL &dv
variety of joint projects in the applications of Photovoltaic conversion of solar energy into P`

electricity. j_c+. iET
The Overall programme is headed by an Executive Committee composed of one representative VDn:SGj5
from each participating country, while the management of individual research projects (Tasks) JqEb;NiP)5
is the responsibility of Operating Agents. Currently nine Tasks have been established in the XhA4:t
IEA PVPS programme. UkfA}b^@v

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, hS_.l}0yf
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV s41adw >
systems will continue to represent a significant PV market segment, not only in developing PWG;&ma
countries, but also in the important home markets of industrial countries. Experts from 15 IEA C P&o%Uc*
countries are sharing their experiences in this area. LG6I_[
This battery guide is intended for a wide use also close to the end customers to increase the -TZ^ ~s
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle I>hmbBlDv
cost for battery storage in small stand alone photovoltaic systems. Also some basic b 9#m m
environmental concerns are addressed. The report has been prepared under the supervision of . s-5N\
