The international Energy Agency (IEA) founded in November 1974, is an autonomous body >=`c [=:Z_
within the framework of the Organisation for Economic Co-operation and Development 8x9kF]=
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 $HXB !$d
member countries. The European Commission also participates in the work of the Agency. R`* *!ku
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ~`})x(!
agreements established within the IEA, and since 1993, its Participants have been conducting a ~4>Xi*

variety of joint projects in the applications of Photovoltaic conversion of solar energy into vW{cB y
electricity. h/fCCfO,
The Overall programme is headed by an Executive Committee composed of one representative @\D D|o67
from each participating country, while the management of individual research projects (Tasks) x<Zhj3
is the responsibility of Operating Agents. Currently nine Tasks have been established in the B![5+
IEA PVPS programme. Ds

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, @gqw] _W
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV S[a5k;8GL
systems will continue to represent a significant PV market segment, not only in developing g& "( - :
countries, but also in the important home markets of industrial countries. Experts from 15 IEA (v`;ym
countries are sharing their experiences in this area. Z8&C-yCC
This battery guide is intended for a wide use also close to the end customers to increase the V{h@nhq
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle R2$ U K
cost for battery storage in small stand alone photovoltaic systems. Also some basic AIm$in`P
environmental concerns are addressed. The report has been prepared under the supervision of )RYnRC#O
