6 FAQs about [Solar panel sensing principle]

How does a sun sensor work in photovoltaic panels?

Yilmaz et al. proposed and tested a sun sensor for photovoltaic panels, which was composed of two photoresistors placed at 180° and separated by a thin wall, as shown in Fig. 15. This sensor detected the Sun's position based on the light intensity. When the Sun moved, the wall produced a shade in some photoresistors.

How to calibrate a solar position sensor?

The calibration process consisted of installing the sun position sensor on the photovoltaic system and calibrating it perpendicular to the surface of photovoltaic system. The sensor was tested with 50000–70000 lumen. The results revealed that the solar tracking error was of 5° with a maximal FOV of 90°.

How does a solar pointing sensor work?

The sensor is composed of an integrated silicon solar cell, a DC/DC converter, a membrane, and patch antenna. Its working principle is based on the operation principles of the sun-pointing sensor. The advantage of this sensor is that can operate at temperatures of ± 150, without wired connection with a FOV of ± 120 °, and an accuracy 0.1°.

How does a solar sensor measure the sun's position?

The sensor was designed to measure the Sun's position by comparing the current of each photodiode. Moreover, the author included an algorithm with astronomical formulas to track the sun when the solar radiation was ≤ 400 W / m 2.

Why do solar panels have orientation problems?

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.

How does a solar sensor work?

The solar sensor had the form of a two-axis analog device, which measured the sun's location relative to its optical axis based on the differential signal obtained from a quadrant silicon detector upon which a circular spot generated by the sun's irradiance was imaged.
