Basic knowledge of photovoltaic tracking brackets

How does a photovoltaic tracking system work?

This designed tracking system was experimentally tested using two photovoltaics. The photovoltaics are driven by a PIC microcontroller based on a tracking algorithm for economic and maximum power harvesting. The photovoltaics are arranged in the form of a triangle located opposite of each other.

What are the parameters of a solar tracking system?

Latitude, angle of incidence, light intensity, tilt angle, orientation angle, solar azimuth angle, declination angle, inclination angle, elevation angle, and zenith angle are the main parameters that specify the best location and direction of solar tracking systems.

What factors affect the energy output of photovoltaic tracking systems?

Several factors that affect the energy output of such systems include the photovoltaic material, geographical location of solar irradiances, ambient temperature and weather, angle of sun incidence, and orientation of the panel. This study reviews the principles and mechanisms of photovoltaic tracking systems to determine the best panel orientation.

What are the different types of active solar tracking?

Aman et al. classified active solar tracking into four categories, namely, triangular solar panel, single axis tracking, double-axis tracking, and spin cell, as shown in Fig. 16. The triangular tracking system uses two solar photovoltaic modules facing opposite directions, and both modules can receive equal amounts of sunlight.

How to categorize solar tracking systems based on control methods?

This study is to categorize the solar tracking systems based on their control methods. Different principles are presented in a chronological order: from passive trackers to tracking systems that employ the artificial intelligence (AI). Section 2 discuss solar tracking systems and a few important parameters for their installation.

What metric should be used for solar tracking systems?

The most important metric to assist the proposed solar tracking systems is calculating the gained energy compared with the consumed energy by the tracker components. Motors, hardware components, resistors, and the size of photovoltaic panels can affect the gained power. The difference between real and expected results is also a an important point.
