Foreword F 973U
The international Energy Agency (IEA) founded in November 1974, is an autonomous body ;-w PXXR
within the framework of the Organisation for Economic Co-operation and Development Jywz27j
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 o%s}jBo}
member countries. The European Commission also participates in the work of the Agency. (B4 A$t
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D }tg n1xpx
agreements established within the IEA, and since 1993, its Participants have been conducting a `9NnL.w!
variety of joint projects in the applications of Photovoltaic conversion of solar energy into JH,fg K+[
electricity. gG? *Fi
The Overall programme is headed by an Executive Committee composed of one representative G(,~{N||
from each participating country, while the management of individual research projects (Tasks) ~ZIRCTQ"
is the responsibility of Operating Agents. Currently nine Tasks have been established in the im%3*bv-
IEA PVPS programme. `Y$5g~3.

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, > %*X2'^
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Qi L
systems will continue to represent a significant PV market segment, not only in developing eNsku G|1
countries, but also in the important home markets of industrial countries. Experts from 15 IEA qf {B
countries are sharing their experiences in this area. jiD8|%}v
This battery guide is intended for a wide use also close to the end customers to increase the ?Gu>!7
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle - C]a2
cost for battery storage in small stand alone photovoltaic systems. Also some basic TniKH( w/
environmental concerns are addressed. The report has been prepared under the supervision of J<O_N~$$*
