The international Energy Agency (IEA) founded in November 1974, is an autonomous body 9NX/OctFa'
within the framework of the Organisation for Economic Co-operation and Development tvh)N{j
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 LP_w6fjT
member countries. The European Commission also participates in the work of the Agency. K0681_bp
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D f@:.bp8VB8
agreements established within the IEA, and since 1993, its Participants have been conducting a B2}|b^ 'I
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 9rO,h|L
electricity. e!+_U C
The Overall programme is headed by an Executive Committee composed of one representative IF"-{@
from each participating country, while the management of individual research projects (Tasks) FQc8j:'
is the responsibility of Operating Agents. Currently nine Tasks have been established in the B?;!j)FUtt
IEA PVPS programme. :?LUv: G

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, cr;\;Ta_!W
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV RtE2%d$ JT
systems will continue to represent a significant PV market segment, not only in developing & f2'cR
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Re`'dde=
countries are sharing their experiences in this area. mW_B|dM"
This battery guide is intended for a wide use also close to the end customers to increase the )FF3|dZ";K
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle BQ\o?= {
cost for battery storage in small stand alone photovoltaic systems. Also some basic 8OYw72&
environmental concerns are addressed. The report has been prepared under the supervision of ups] k?4
