6 FAQs about [Bidirectional adjustment principle of photovoltaic bracket]

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

How does optimum tilt angle affect solar power yield?

On average, PV panels fixed at the optimum tilt angle increase the annual power yield by 13.7% in comparison to horizontally fixed panels. Additional gains can be achieved at 4.5%, 5.5%, 18.0%, and 38.7% for quarterly adjusted, monthly adjusted, 1-axis tracking and 2-axis tracking PV systems, respectively.

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 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.

Does coupling more atmospheric factors improve optimum PV tilt angles?

These studies revealed that coupling more atmospheric factors can achieve better performance in estimating the optimum PV tilt angles. However, the simulation results were obtained by maximizing the amount of incident solar radiation on PV panel surface, without considering the actual photoelectric conversion process and PV system losses.

How do atmospheric factors affect optimum PV tilt angles?

Nicolás-Martín et al. presented a model for the annual optimum tilt angle as a function of latitude, diffuse fraction and albedo in the absence of meteorological data. These studies revealed that coupling more atmospheric factors can achieve better performance in estimating the optimum PV tilt angles.
