Foreword _p\O!y
The international Energy Agency (IEA) founded in November 1974, is an autonomous body f%Vdao [
within the framework of the Organisation for Economic Co-operation and Development w~} .c:B
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 }WEF *4B!
member countries. The European Commission also participates in the work of the Agency. (bON[6OGm
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D >^ zbDU1wT
agreements established within the IEA, and since 1993, its Participants have been conducting a hO0g3^
variety of joint projects in the applications of Photovoltaic conversion of solar energy into X!!3>`|
electricity. I hPX/P
The Overall programme is headed by an Executive Committee composed of one representative )m.U"giG++
from each participating country, while the management of individual research projects (Tasks) io Jr2wq6
is the responsibility of Operating Agents. Currently nine Tasks have been established in the *1CZRfWI
IEA PVPS programme. 0=V

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, &@/25Y2
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV y sFp`
systems will continue to represent a significant PV market segment, not only in developing p5 JRG2zt
countries, but also in the important home markets of industrial countries. Experts from 15 IEA E% d3}@
countries are sharing their experiences in this area. GLr7sack
This battery guide is intended for a wide use also close to the end customers to increase the )T!3d u:M
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle y$U(oIU>
cost for battery storage in small stand alone photovoltaic systems. Also some basic 3jDAj!_e a
environmental concerns are addressed. The report has been prepared under the supervision of ,8Q&X~$rY
