Foreword xK!DtRzsA
The international Energy Agency (IEA) founded in November 1974, is an autonomous body iwkJ~(5z
within the framework of the Organisation for Economic Co-operation and Development '{^8_k\}B
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 #[,= 1Od(q
member countries. The European Commission also participates in the work of the Agency. :tlE`BIp
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D gD5P!}s[u0
agreements established within the IEA, and since 1993, its Participants have been conducting a a],h<wGEx
variety of joint projects in the applications of Photovoltaic conversion of solar energy into =f4< ({9
electricity. 7AeP Gr
The Overall programme is headed by an Executive Committee composed of one representative |Pf(J;'[
from each participating country, while the management of individual research projects (Tasks) 2|s<[V3rP-
is the responsibility of Operating Agents. Currently nine Tasks have been established in the AI R{s7N
IEA PVPS programme.

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, rkq)&l=ny
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV . o"<N
systems will continue to represent a significant PV market segment, not only in developing %2zas(b9j
countries, but also in the important home markets of industrial countries. Experts from 15 IEA }Qb';-+;d
countries are sharing their experiences in this area. 9 c6 '
This battery guide is intended for a wide use also close to the end customers to increase the 86#-q7 aX
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle }"0{zrz
cost for battery storage in small stand alone photovoltaic systems. Also some basic BP:(IP!&
environmental concerns are addressed. The report has been prepared under the supervision of >.LgsMRIKi
