The international Energy Agency (IEA) founded in November 1974, is an autonomous body / FA0(< -}
within the framework of the Organisation for Economic Co-operation and Development 5<L+T
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 `'M}.q,k~
member countries. The European Commission also participates in the work of the Agency. |fg{F pc
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D [f\TnXq24
agreements established within the IEA, and since 1993, its Participants have been conducting a p>GxS E)
variety of joint projects in the applications of Photovoltaic conversion of solar energy into 2 1]8 7$
electricity. fkK42*U@r
The Overall programme is headed by an Executive Committee composed of one representative 5$L=l
from each participating country, while the management of individual research projects (Tasks) o-%DL*^5
is the responsibility of Operating Agents. Currently nine Tasks have been established in the tJ!s/|u(
IEA PVPS programme. @F0+t;
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark fr([g?F%D

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, $oU40HA)W]
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV eNw9"X}g
systems will continue to represent a significant PV market segment, not only in developing D\i8WU
countries, but also in the important home markets of industrial countries. Experts from 15 IEA Fb9!x/$tGV
countries are sharing their experiences in this area. %vFoTu)2
This battery guide is intended for a wide use also close to the end customers to increase the t^-yK;`?q:
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle HCTjFW>C
cost for battery storage in small stand alone photovoltaic systems. Also some basic {P@ OV1
environmental concerns are addressed. The report has been prepared under the supervision of SN/
