The international Energy Agency (IEA) founded in November 1974, is an autonomous body 3; A1[E6K
within the framework of the Organisation for Economic Co-operation and Development /bWV `*
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 IX}l)t[:(
member countries. The European Commission also participates in the work of the Agency. Po5}Vh
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D [kCn6\_<V
agreements established within the IEA, and since 1993, its Participants have been conducting a x {rt\OT
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 04s N 4C
electricity. \ys3&<;b
The Overall programme is headed by an Executive Committee composed of one representative MmX42;Pw
from each participating country, while the management of individual research projects (Tasks) 2}NfR8
N
is the responsibility of Operating Agents. Currently nine Tasks have been established in the
#xmUND`@
IEA PVPS programme.

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, ! `SR$dnE
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV [-l^,,E
systems will continue to represent a significant PV market segment, not only in developing *q^ '%'
countries, but also in the important home markets of industrial countries. Experts from 15 IEA v#~,)-D&
countries are sharing their experiences in this area. ~Sh}\&3p
This battery guide is intended for a wide use also close to the end customers to increase the &rn,[w_F[
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle \1tce`+
cost for battery storage in small stand alone photovoltaic systems. Also some basic t* COzE
environmental concerns are addressed. The report has been prepared under the supervision of RKe19l_V
