Table 1: Specifications of some PV power plants located in Spain. Some of the publications on single-axis solar trackers that take into account the limit of movement include the following:  
1. In [11], the optimal deployment of horizontal single-axis trackers in a terrain characterised by its tilt angle and variable orientation was studied. A single movement limit of \(\pm 55\) (\({}^{\circ}\)) was used without considering the effects of this parameter on the results of incident solar irradiance on the \(PV\) field. 2. [PERSON] [12] analysed a real \(PV\) power plant from the point of view of the tilt angle and orientation of the horizontal single-axis trackers. A movement limit of \(\pm 55\) (\({}^{\circ}\)) was used without further investigation of the influence of this parameter. 3. [PERSON] et al. [13] presented a study on backtracking strategies in horizontal single-axis trackers. The objective of the work was to choose the backtracking strategy that optimised the incident solar irradiance on the \(PV\) field. This paper took into account the limit of movement, which remained constant throughout the study at a value of \(\pm 50\) (\({}^{\circ}\)). Therefore, this study did not take into account the influence of the movement limit of the solar tracker on the incident solar irradiance on the \(PV\) field. 4. The optimisation of \(PV\) power plants with horizontal single-axis trackers was the subject of the study presented in [9]. In this work, equations were presented for the calculation of the incident solar irradiance on the \(PV\) field, which took into account several design parameters such as the irregular shape of the terrain, the size and configuration of the \(PV\) module mounting system, the row spacing, the operating periods, and the optimal deployment of the \(PV\) module mounting systems. A movement limit of \(\pm 60\) (\({}^{\circ}\)) was used, but the influence of this parameter was not taken into account. 5. A study on tree crops between rows of horizontal single-axis trackers was presented in [14]. A movement limit of \(\pm 55\) (\({}^{\circ}\)) was chosen, without analysing the influence of this factor. 6.
