In this study, we collected the hourly data from 2007 to 2018 and used multi-year averages to calculate the spatial distribution of optimum tilt angles for PV installation. Due to the difference in observation scale, there are systematic deviations for satellite-based data in comparison to ground measurements [ 42 ].
This article uses Ansys Workbench software to conduct finite element analysis on the bracket, and uses response surface method to optimize the design of the angle iron structure that makes up the bracket. The overall model of the bracket before and after optimization is analyzed and compared.
The best slope angle that gives the greatest solar radiation can be determined by calculating the slope angle when it is change from 0º to 90º skipping one degree and choosing the largest radiation that corresponds to the optimal angle.

6 FAQs about [Calculation method of the slope of photovoltaic bracket]
What affects the optimum tilt angle of a photovoltaic module?
(vi) The tilt angle that maximizes the total photovoltaic modules area has a great influence on the optimum tilt angle that maximizes the energy.
What is the optimum tilt angle for a solar PV system?
Cheng et al. found that more than 98% of south-faced PV systems in 14 countries achieved the optimal performance at a tilt angle equal to the latitude. In North America, the optimum tilt angle is slightly less than the latitude [16, 17]. Some studies suggest that more complex models are necessary for world estimates of the optimum tilt angle.
Why is the slope angle of solar panels important?
The preeminent slope angle of solar panels is an important determinant of falling solar radiation on the surface of photovoltaic panels. Characteristics of the position of latitude, the sun, and local geography must be explained and understood to determine the slope angle correctly.
Why does the tilt angle of PV panels change?
The optimum tilt angle at the same location changes periodically (Fig. 7) due to the Earth revolution around sun. In summer, when the sun shines more directly on the northern hemisphere, the tilt angle is generally small; winter is the opposite. Adjusting the tilt angle of PV panels according to the season helps capturing more energy.
What is the optimum tilt angle for a south facing solar panel?
Ulgen calculated the optimum tilt angle and its power for Izmir, Turkey. The results showed that annual tilt angle and its power were 30.3° and 6397 Mj/m 2 year for a south facing solar panel (Ulgen 2006). Using a mathematical model, Kacira et al. investigated the monthly optimum tilt angle for south facing for Sanliurfa, Turkey.
Does cloudy conditions affect the tilt angle of PV panels?
The influence of cloudy conditions on the tilt angle is explored. It is demonstrated that more energy can be extracted from the PV system in cloudy conditions when the tilt angle of the panel is decreased compared to when the panel is aimed to be facing directly normal to the sun.
