“…Failing to account for shading by neighboring collectors, referred to as self-shading, results in an overestimation of power production at low solar elevation angles. Typical annual shading losses are between 1% for sparse field layouts and 6% for dense field layouts [ 3 ]. As accurate yield estimations are critical to obtaining financing for solar energy projects, it is imperative that validated methods are available for accounting for shading.…”

“…In addition to the branches of studies mentioned to increase the performance of PV modules, there are researches and applications that combine them with other technologies/devices, such as solar concentrators (Placha, 2017;Rana et al, 2018;Gonzatti et al, 2017) and solar tracking in one and/or two axes (Jamroen et al, 2021;Jensen et al, 2022;Wu et al, 2022). How the generated electric current of a PV cell is directly dependent on the solar irradiation (Kumar et al, 2020), the maximum power generation is achieved when the PV cell is placed orthogonally to the Sun, ensuring the maximum incidence of direct sunlight over the cell's surface.…”

The photovoltaic module position related to the Sun greatly affects its power production due to the latter being dependent on the irradiation incidence. One-axis trackers are used to physically move the modules so they follow the Sun's daily trajectory and hence increase energy harvesting. This paper investigates how relevant the actuating angular step of a one-axis tracker is concerning the daily and annual energy photovoltaic energy production. An east-west rotational axis with a fixed tilt angle is experimentally analyzed with four different steps: 2°, 5°, 10°, and 30°angular movements. Results are obtained over 1 year and compared to the energy production of a fixed mount photovoltaic module. Only a maximum difference of 1.68% is observed between the tracking strategies. The sky's condition is also considered, where clear or mostly clear days (60.9% of the analyzed period) contributed to 78.8% of energy production.

“…In its application, the photovoltaic semiconductor plate will receive maximum solar ISSN: 2302-9285  irradiation if the direction of the incident photons is perpendicular to the surface of the solar panel [4], [5]. Thus, PSH has a value of 3-7 hours per day depending on the geographical and astronomical location of an area and the slope of the solar panel surface [6]- [10].…”

A solar cell is a type of renewable energy engineering technology that can convert photons coming from the sun to be converted into electrical energy. The amount of energy that can be converted by a solar cell is determined by the effective insolation time. Peak sun hours (PSH) are the focus of this research. This PSH analysis aims to determine the potential for solar energy obtained in geographical locations throughout the year. Geographical location and the position of the astronomical coordinates of a certain area affect PSH. Therefore, the orientation of solar panel installation, including the height, slope, and latitude of the solar panel surface needs to be considered in order to get maximum solar energy. The results of this study can be used by technicians in determining the orientation of solar panel development in an area.
