A comparative analysis of MPPT with tracking panel mechanism and fixed panel arrangement

Abstract

The growing demand of electricity day by day and growing concern regarding environment pollution has bring humans to think about an alternate for production of energy using clean, renewable sources such as solar energy. In all renewable energy sources the solar energy is the best, to convert sun ray’s to electrical energy. In this paper firstly mechanical tracking of the sun, using Arduino is proposed to extract maximum irradiation from the sun by keeping the solar panel perpendicular to the irradiation. Secondly by getting the maximum solar irradiation as input to the solar panel, output from the PV (i.e. voltage and current) fed to a power interface Buck-Boost converter through a MPPT control technique to operate the operating point always at peak. Electrical tracking is done using P&O algorithm MPPT technique. The objective is to get maximum irradiation and Maximum power at each and every moment.
