Photovoltaic panel steering machine

How are photovoltaic panels tracked?

They can also be distinguished by two tracking techniques: The MPPT (maximum power point tracking) method which is based on an algorithm to find the maximum power curve of the photovoltaic panel, or the sun tracking system, which is based on the orientation of solar panels throughout the day to better exploit the photovoltaic cells [4, 5].

How are LDRs used in a solar photovoltaic module?

The LDRs were used to determine the position and direction of the solar photovoltaic module. Two pairs of LDRs were fixed to the solar panels, and the differences between the measured current signal by LDRs in each group were utilized to trigger DC motors.

How to maximize photovoltaic module generated power using ANFIS controller?

Sharma et al. proposed a high performance tracking system to maximize the photovoltaic module generated power by using ANFIS controller. The ANFIS controller was utilized to determine the optimum duty cycle that can be fed directly to the buck-boost convertor by using temperature and solar irradiance.

Can artificial neural network control a tracking power photovoltaic system?

Makhloufi et al. designed and implemented a tracking power photovoltaic system using an artificial neural network control strategy to maximize the gained power. The idea is to perform a simulation study of the MPP tracking method using an artificial neural network to control the photovoltaic modules.

How does a photovoltaic module work?

A stepper motor was used to rotate the photovoltaic module from one side to another, and a real-time clock microcontroller was used to find the suitable angles and feed them directly to the stepper motor. The microcontroller depends on using an algorithm that can calculate the positions and directions of the solar panel.

Why do photovoltaic panels have orientation problems?

Authors to whom correspondence should be addressed. After installing a solar panel system, the orientation problem arises because of the sun’s position variation relative to a collection point throughout the day. It is, therefore, necessary to change the position of the photovoltaic panels to follow the sun and capture the maximum incident beam.
