The international Energy Agency (IEA) founded in November 1974, is an autonomous body U_n9]Z
within the framework of the Organisation for Economic Co-operation and Development `u
teg=
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 !~rY1T~
member countries. The European Commission also participates in the work of the Agency. 9|gr0&#~j
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D yU-e3O7 L
agreements established within the IEA, and since 1993, its Participants have been conducting a &N\jG373
variety of joint projects in the applications of Photovoltaic conversion of solar energy into r'HtZo$^R
electricity. E(8*

The Overall programme is headed by an Executive Committee composed of one representative L"4mL,
from each participating country, while the management of individual research projects (Tasks) g9Xu@N;bL
is the responsibility of Operating Agents. Currently nine Tasks have been established in the ,l:ORoND
IEA PVPS programme. $4 S@

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, n O\"HLM
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV V4'YWdTi
systems will continue to represent a significant PV market segment, not only in developing @ W[f 1
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Hn%xDJ'
countries are sharing their experiences in this area. _0]S69lp
This battery guide is intended for a wide use also close to the end customers to increase the yl7&5)b#9
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle t>`a sL
cost for battery storage in small stand alone photovoltaic systems. Also some basic $JMXV
environmental concerns are addressed. The report has been prepared under the supervision of \%f q
