The international Energy Agency (IEA) founded in November 1974, is an autonomous body !?]NMf_
within the framework of the Organisation for Economic Co-operation and Development :=-h'<D
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 zE<}_nA
member countries. The European Commission also participates in the work of the Agency. q

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D hEDj"`Px
agreements established within the IEA, and since 1993, its Participants have been conducting a PQ1\b-I
variety of joint projects in the applications of Photovoltaic conversion of solar energy into cd \0
electricity. =YI<L8@g~
The Overall programme is headed by an Executive Committee composed of one representative I"r*p?
from each participating country, while the management of individual research projects (Tasks) Tc{r}y[)
is the responsibility of Operating Agents. Currently nine Tasks have been established in the 8USF; k
IEA PVPS programme. OD{R h(Id

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, w_6h

quality assurance and technical surveys on stand alone PV applications. Stand-alone PV

systems will continue to represent a significant PV market segment, not only in developing jy tfGE:
countries, but also in the important home markets of industrial countries. Experts from 15 IEA ^ *RmT
countries are sharing their experiences in this area. CJ?Lv2Td
This battery guide is intended for a wide use also close to the end customers to increase the f ~9 ADb
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle 7n5 bI\
cost for battery storage in small stand alone photovoltaic systems. Also some basic {R\ "x|
environmental concerns are addressed. The report has been prepared under the supervision of "QA!z\ 0\
