Greater performances of ST are achieved through a number of tracking control arrangements in either double or single axis solar tracking systems [131]. If not optimized, these systems suffer from poor performance and poor accuracy due to their inability to determine the exact position of the sun [128]. The double axis ST need at least a pair

Dual closed-loop control algorithm for one-axis solar trackers. Visual-based device to estimate the Sun''s apparent position. High thermal efficiency of PTC systems due to low solar tracking error. Parabolic trough systems require accurate, reliable, and robust solar trackers to achieve their maximum thermal efficiency.
Most established trough-thermal-power-generation-based power plants applied single-axis solar tracking modes. The aforementioned research also found that, among the single-axis solar tracking modes, the north-south tilt tracking mode receives more direct solar radiation than the north-south Earth''s axis tracking mode in 7 months of a year.
Therefore, for the purpose of optimizing the tracking mode of the parabolic trough concentrating collectors, the current work applied Hottel’s clear-day radiation model with an aim to study the amount of direct solar radiation received by the parabolic mirror within a year under different tracking modes in Shanghai.
Depending on the number of tracking axes, the tracking modes of parabolic trough concentrating collectors can be classified as dual-axis and single-axis solar tracking modes.
During the peak months of the Covid-19, Ukraine’s largest solar plant with trackers provided a challenging but ideal test bench to Soltigua’s remote commissioning processes. Supporting Greengenius, Soltigua successfully concluded the commissioning of trackers for a 33 MW plant in Lyubar (Zhytomyr...
Single-axis solar tracking follows either one of the elevation angle or azimuth, which can be accomplished by ensuring the incident light falls on the plane formed by the primary optical axis and the focal line .
In April and August, the north-south tilt tracking mode (tilt angle = 15°) can collect the most solar radiation; in May, June and July, the north-south horizontal tracking mode behaves the best in receiving solar radiation.
Mao studied the single-axis parabolic trough collectors [11, 12] and found the thermal output of the north-south tracking mode to be significantly higher than the east-west tracking mode in summer and the other way around in winter.
