The international Energy Agency (IEA) founded in November 1974, is an autonomous body ,; ~@t:!c
within the framework of the Organisation for Economic Co-operation and Development ZDTp/5=?K/
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 J*m ~fZ^
member countries. The European Commission also participates in the work of the Agency. 5~ \GAjf
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ]o2 Z 14
agreements established within the IEA, and since 1993, its Participants have been conducting a CN !~(1 v
variety of joint projects in the applications of Photovoltaic conversion of solar energy into WN3] xw3
electricity. |nT+ W| 0U
The Overall programme is headed by an Executive Committee composed of one representative {mmQv~|5q
from each participating country, while the management of individual research projects (Tasks) NW`L6wgl
is the responsibility of Operating Agents. Currently nine Tasks have been established in the tq&CJv J4
IEA PVPS programme. Zg/

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, {D7v[P+
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV 53O}`xX!6
systems will continue to represent a significant PV market segment, not only in developing B
f"L;L
countries, but also in the important home markets of industrial countries. Experts from 15 IEA =q?s B]n
countries are sharing their experiences in this area. tde&w= ec
This battery guide is intended for a wide use also close to the end customers to increase the EJa Gz\\
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle z-G*:DfgH
cost for battery storage in small stand alone photovoltaic systems. Also some basic <jIuVX
environmental concerns are addressed. The report has been prepared under the supervision of ~xU\%@I\
