The international Energy Agency (IEA) founded in November 1974, is an autonomous body u2p5* gzZ
within the framework of the Organisation for Economic Co-operation and Development =v (MdjwFl
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 !kzC1U
member countries. The European Commission also participates in the work of the Agency. 7.G1Q]6/
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D +@
'( N
agreements established within the IEA, and since 1993, its Participants have been conducting a W6=j^nv
variety of joint projects in the applications of Photovoltaic conversion of solar energy into WGx e3(d
electricity. iymOq9
The Overall programme is headed by an Executive Committee composed of one representative ML6V,-KU
from each participating country, while the management of individual research projects (Tasks) eh@6trzp=
is the responsibility of Operating Agents. Currently nine Tasks have been established in the u!iBAr5
IEA PVPS programme. 8A|{jH74

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, q?J d.r5*
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV ~ S5wfx&
systems will continue to represent a significant PV market segment, not only in developing pI__<
countries, but also in the important home markets of industrial countries. Experts from 15 IEA CA0SH{PdW&
countries are sharing their experiences in this area. c^N'g!on
This battery guide is intended for a wide use also close to the end customers to increase the 8XwZJ\5
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle urJ>dw ?FI
cost for battery storage in small stand alone photovoltaic systems. Also some basic dr25;L? B
environmental concerns are addressed. The report has been prepared under the supervision of }7`HJ>+m)H
