The international Energy Agency (IEA) founded in November 1974, is an autonomous body O 6pjuhMx
within the framework of the Organisation for Economic Co-operation and Development tL~|/C)d R
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 mKg~8q 3
member countries. The European Commission also participates in the work of the Agency. !>tXib]:
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D ,-b9:]{L
agreements established within the IEA, and since 1993, its Participants have been conducting a ,P|PPx%@
variety of joint projects in the applications of Photovoltaic conversion of solar energy into ?aCR>AY5X
electricity. D fb& / }
The Overall programme is headed by an Executive Committee composed of one representative qH

from each participating country, while the management of individual research projects (Tasks) 6$f,DU
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ^c5(MR 7LD
IEA PVPS programme. Nl+ 2m4

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, A1C@'9R*
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV Z(Vr mz2.
systems will continue to represent a significant PV market segment, not only in developing Gd"*mL d
countries, but also in the important home markets of industrial countries. Experts from 15 IEA )fa
countries are sharing their experiences in this area. y.nw6.`MR
This battery guide is intended for a wide use also close to the end customers to increase the Gc'H F"w
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle A!J5Wz>Q5
cost for battery storage in small stand alone photovoltaic systems. Also some basic YJ9 _cA'A
environmental concerns are addressed. The report has been prepared under the supervision of 0nS6<:
