The international Energy Agency (IEA) founded in November 1974, is an autonomous body qr<+@Q
within the framework of the Organisation for Economic Co-operation and Development
BH<jnQ
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 `mt x+C
member countries. The European Commission also participates in the work of the Agency. ,B'n0AO/'
The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D 4WAs_~
agreements established within the IEA, and since 1993, its Participants have been conducting a o8ERU($/
variety of joint projects in the applications of Photovoltaic conversion of solar energy into n N_Ylw
electricity. N!Q~?/!d
The Overall programme is headed by an Executive Committee composed of one representative QnZ7e#@UP
from each participating country, while the management of individual research projects (Tasks) `Lr I^9Z
is the responsibility of Operating Agents. Currently nine Tasks have been established in the R'z

Task III of the PVPS programme, active since 1993, focuses on the exchange of information, 3

quality assurance and technical surveys on stand alone PV applications. Stand-alone PV z0F'zN3J
systems will continue to represent a significant PV market segment, not only in developing hgU#2`fS
countries, but also in the important home markets of industrial countries. Experts from 15 IEA aGx[?}=
countries are sharing their experiences in this area. C4h4W3w
This battery guide is intended for a wide use also close to the end customers to increase the Y@#rGV>
