The international Energy Agency (IEA) founded in November 1974, is an autonomous body 3?]81v/
within the framework of the Organisation for Economic Co-operation and Development ;M4[Liw~O
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 ] Z8u0YtM)
member countries. The European Commission also participates in the work of the Agency. /}8Au$nA
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Pd" c*n&9
agreements established within the IEA, and since 1993, its Participants have been conducting a c]aU}[s1
variety of joint projects in the applications of Photovoltaic conversion of solar energy into [Tp?u8$p`
electricity. qpYgTn8l7
The Overall programme is headed by an Executive Committee composed of one representative `?(J(H
from each participating country, while the management of individual research projects (Tasks) n-cI~Ax+4
is the responsibility of Operating Agents. Currently nine Tasks have been established in the "5~?`5Ff
IEA PVPS programme. R P<M

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, K6p\ >J
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV yVmp,""a
systems will continue to represent a significant PV market segment, not only in developing WX? nq'nr
countries, but also in the important home markets of industrial countries. Experts from 15 IEA 1bCE~,tD
countries are sharing their experiences in this area. \EVT*v=}/
This battery guide is intended for a wide use also close to the end customers to increase the /-[vC$B"
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle PKrG6%

cost for battery storage in small stand alone photovoltaic systems. Also some basic K}re{y
environmental concerns are addressed. The report has been prepared under the supervision of .eD&UQ
