Go to Editorial ManagerEngineers are searching for alternatives to conventional energy sources to address the energy crisis as a result of the sharp increase in energy usage. This work describes developing, simulating, and evaluating a three-phase, 13.25 kW solar power system. PV analysis is also performed. An inverter featuring a dual Electricity flow is connected to a solar system consisting of six consecutive strings of four solar power cells connected in series. The output of the phase lock loop (PLL) feedback in the linearization system is used to generate a signal, and the power conversion voltage is synchronized with the signal by using its output as a voltage reference. This hybrid technology, which has two phases that are optimal for the rechargeable recharging process of the batteries, is used to replenish a battery bank in capacity or float arrangement for eight sequences of 12V - 200-Ah rechargeable batteries. Ultimately, a MATLAB computational model has been created for a grid-connected photovoltaic system that uses sinusoidal modulation of pulse width and an inverter as voltage sources.
Solar power is environment friendly power source, but it is characterized by being highly dependent on the irradiation level witch is function of the sun position in the sky. To overcome this situation and extract maximum power from the sun, the PV array must be kept nearly perpendicular to the sun during the daytime. In this paper, a smart relay based sun tracking system has been designed and implemented to keep the PV array perpendicular to the sun during the day hours.
