The international Energy Agency (IEA) founded in November 1974, is an autonomous body X NJ4T]><
within the framework of the Organisation for Economic Co-operation and Development ]i*ucW4
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 eTuqK23
member countries. The European Commission also participates in the work of the Agency. _VrY7Mz:r
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D )j_El ]?
agreements established within the IEA, and since 1993, its Participants have been conducting a W:d

variety of joint projects in the applications of Photovoltaic conversion of solar energy into Mkz_.;3
electricity. ~ nsb
The Overall programme is headed by an Executive Committee composed of one representative Y9+_MxC"
from each participating country, while the management of individual research projects (Tasks) 0xB2
is the responsibility of Operating Agents. Currently nine Tasks have been established in the wX,V:QE
IEA PVPS programme. =gB5JB<}2

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 7>E.0 D P
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV AcH-TIgM/
systems will continue to represent a significant PV market segment, not only in developing *T5;d h (
countries, but also in the important home markets of industrial countries. Experts from 15 IEA cl4 E6\?z
countries are sharing their experiences in this area. L|=5jn9 :
This battery guide is intended for a wide use also close to the end customers to increase the Q.mJ7T~T
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle >fPo_@O
cost for battery storage in small stand alone photovoltaic systems. Also some basic $83B10OQ&L
environmental concerns are addressed. The report has been prepared under the supervision of NX @FUct;
