Foreword sFTIRVXN,
The international Energy Agency (IEA) founded in November 1974, is an autonomous body >vU
Hf`4T
within the framework of the Organisation for Economic Co-operation and Development #rwR)9iC0
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 /~[R
u
member countries. The European Commission also participates in the work of the Agency. > R <fm
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D kes'q8k
agreements established within the IEA, and since 1993, its Participants have been conducting a e{,/
variety of joint projects in the applications of Photovoltaic conversion of solar energy into u/f&Wq/
electricity. A ngwBZ@
The Overall programme is headed by an Executive Committee composed of one representative ~e<<aTwN
from each participating country, while the management of individual research projects (Tasks) 4#w^PM8}
is the responsibility of Operating Agents. Currently nine Tasks have been established in the :S12=sFl$
IEA PVPS programme. di 5_5_$`o

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 4;||g@f'[
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV s|T7)PgR
systems will continue to represent a significant PV market segment, not only in developing F e .*O`
countries, but also in the important home markets of industrial countries. Experts from 15 IEA )QD}R36Ic
countries are sharing their experiences in this area. [B o $?
This battery guide is intended for a wide use also close to the end customers to increase the >``GDjcJ
