Foreword f e6Op
The international Energy Agency (IEA) founded in November 1974, is an autonomous body lzFg(Ds!f
within the framework of the Organisation for Economic Co-operation and Development HF& d HD2f
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 <T'fJc R
member countries. The European Commission also participates in the work of the Agency. `N7e rM
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D uuUj IZCtz
agreements established within the IEA, and since 1993, its Participants have been conducting a /'v!{m
variety of joint projects in the applications of Photovoltaic conversion of solar energy into JqN$B\J,
electricity. BlqfST#6
The Overall programme is headed by an Executive Committee composed of one representative g*9 &3ov
from each participating country, while the management of individual research projects (Tasks) E}36
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ;%>X+/. y0
IEA PVPS programme. 0icB2Jm:D}

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, OWN|W,
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV jNIz:_c-~
systems will continue to represent a significant PV market segment, not only in developing i-k(/Y0
countries, but also in the important home markets of industrial countries. Experts from 15 IEA k'[\r>T
countries are sharing their experiences in this area. <(qdxdUp
This battery guide is intended for a wide use also close to the end customers to increase the ov>`MCS,v
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle )pey7-P7g5
cost for battery storage in small stand alone photovoltaic systems. Also some basic =Y3 d~~
environmental concerns are addressed. The report has been prepared under the supervision of noT}NX%
