The international Energy Agency (IEA) founded in November 1974, is an autonomous body *#TYqCc +g
within the framework of the Organisation for Economic Co-operation and Development cS. -7
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 TI !a )X
member countries. The European Commission also participates in the work of the Agency. 1pCieTz!PN
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Lgz$]Jbl8
agreements established within the IEA, and since 1993, its Participants have been conducting a k@ K7yK
variety of joint projects in the applications of Photovoltaic conversion of solar energy into gt\MS;jMa
electricity. vm'5s]kdh
The Overall programme is headed by an Executive Committee composed of one representative ;r /;m\V
from each participating country, while the management of individual research projects (Tasks) jt@S ZI`
is the responsibility of Operating Agents. Currently nine Tasks have been established in the lKkN_ (/j
IEA PVPS programme. #UtFD^h
The Twenty one members are: Australia (AUS), Austria (AUT), Canada (CAN), Denmark kqb0>rYa
(DNK), European Commission, Finland (FIN), France (FRA), Germany (DEU), Israel (ISR), Lw'9
Italy (ITA), Japan (JPN), Korea (KOR), Mexico (MEX), The Netherlands (NLD), Norway 2Sq_Tw3^
(NOR), Portugal (PRT), Spain (ESP), Sweden (SWE), Switzerland (CHE), The United j& UMjI9[
Kingdom (GBR), and The United States (USA). f""`cdqAOh
Task III of the PVPS programme, active since 1993, focuses on the exchange of information, zyg:nKQW
quality assurance and technical surveys on stand alone PV applications. Stand-alone PV {l s+d x /
systems will continue to represent a significant PV market segment, not only in developing a,Gxm!
countries, but also in the important home markets of industrial countries. Experts from 15 IEA JxjI]SF02
countries are sharing their experiences in this area. !m(4F(!"h
This battery guide is intended for a wide use also close to the end customers to increase the o&hIHfZri
hands on battery knowledge and thereby increase the system reliability and reduce the lifecycle ^VT1vu

cost for battery storage in small stand alone photovoltaic systems. Also some basic SI_i I 71
environmental concerns are addressed. The report has been prepared under the supervision of i-U4RZE
