A photovoltaic module is an array of photo voltaic cell when this module expose to solar irradiance, it yields electrical energy in the form of direct current. The source impedance of PV Module functionally follows module surface temperature and intensity of solar irradiance, varies with the position of sun that is ever changing due to tilt in the earth and its elliptical orbit. The maximum energy transfer to load from this PV module is only when load impedance attuned to Maximum Power Point (MPP) in I v/s V characteristic curve of the PV module. An interface needs between load (Solar-Invertor) and PV module. This Maximum Energy Transfer (MET) interface is in the form of Switch Pass regulator, conceive and control vide digital processor. The energy yield is highly efficient and smooth. It is low cost interface suitable for domestic and industrial use from low to higher end in the spectrum of utilisation.
