“…The model proposed in Gonzalez‐Diaz et al 10 describes the physical‐to‐electrical behavior of solar cells with a set of linearized equations considering the influence of temperature and irradiance.

“…The model considers the necessary mathematical description evaluating the temperature and irradiance dependence of the voltage to current and voltage to power values. As an additional contribution, the model synthesis improves the approximation of Gonzalez‐Diaz et al 10 with a simple but effective parameter adjustment approximation. These parameters are correction factors represented by

Summary This manuscript resumes the synthesis of a reliable electrical solar cell model in LTspice. The model improves correspondence with the physical I‐V and P‐V behavior, evaluating the temperature and irradiance dependence with simple approximations. A few electrical parameters into script lines synthesize the nonlinear branch relationship of a voltage‐controlled current source. The LTspice model includes new factors to improve the irradiance and temperature variation evaluation, which is uniform among solar cells.The results exhibit an average error of less than seven percent in an open‐source SPICE solution, similar to cumbersome computational efforts. The SPICE model enables the design of photovoltaic systems taking into account the temperature and irradiance factors with electrical components.

“…Solar cells at constant temperatures have been investigated extensively experimentally and numerically [8][9][10], but very few studies [11,12] explain transient temperature effects. Moreover, studies do not examine an actual site where the levels of temperature change throughout the year, especially in the hot regions, where the effect of temperature rise is critical in a dramatic decrease in solar cell power production.…”

The work of solar cells and their production of electrical energy have been affected by climate change, especially in hot regions which became significantly hotter and still receive relatively high levels of solar radiation throughout the year. Higher ambient temperature and solar radiation result in higher PV cell temperature and, therefore, the reduction in PV module power output and efficiency. This study investigates how a PV module performs throughout the year in a hot region by considering the variations in cell temperature resulting from changes in ambient temperature and solar radiation every day. The tilt angles and two-axis tracking have also been examined. Results indicate that the two-axis solar tracking system is critical to use in hot regions for obtaining higher output power. Therefore, part of this power can be used to cool solar panels using various methods to keep their efficiency high, such as operating air fans or operating pumps to cool them with coolant.

“…The future development goal is to refine the established theoretical model based on the measurement results. There is a large body of literature devoted to the experimental and numerical investigation of solar cells at constant temperatures [3][4][5], but very few researchers [6,7] investigate the phenomenon of transient temperature and its effects. The present study primarily contains results measured and simulated in the transient state, which also represents the novelty of the research work.…”

Many factors determine the efficient operation of a photovoltaic cell. These factors can be the intensity and spectral composition of illumination, the surface temperature, the ambient temperature, and the amount contaminations in the air and on the surface of the cells. The aim of the present study is to describe the effect of temperature gradient on the voltage and amperage changes, as well as the power output of a commercial solar cell through experimental methods and numerical simulations performed in MATLAB. The transient temperature investigations have allowed better understanding the time-dependent behavior of a solar cell under constant intensity illumination. Measurements prove that an increase in the surface temperature of the solar cell significantly reduces its performance. Measurements performed with the solar simulator show good conformity with simulated results.
