6 FAQs about [Photovoltaic support tilt detection]

What is the tilt angle of a photovoltaic support system?

The comparison of the mode shapes of tracking photovoltaic support system measured by the FM and simulated by the FE (tilt angle = 30°). The modal test results indicated that the natural vibration frequencies of the structure remains relatively constant as the tilt angle increases.

What is the optimal tilt angle for a PV panel?

For the chosen location, we calculate the daily energy produced by the PV panel in a tilt range [θ l; θ h] of plus or minus 45° around the absolute value of the latitude of the panel location, which is known to be close to the optimal annual tilt angle. We verified that calculated optimal tilts never exceed this range.

How can modal testing improve tracking photovoltaic support systems under different tilt angles?

Through field modal testing and finite element modal analysis, this study enables us to obtain dynamic parameters of tracking photovoltaic support systems under different tilt angles, including modes, damping ratios, and vibration patterns.

Can adjusting the tilt angle of solar panels improve energy production?

We determined that adjusting the tilt angle of solar panels by a range of approximately ± 9° would result in a decrease of less than 1 % energy production. For short-term installation, the first layer can also be applied to find specific optimal tilts. That could improve the energy produced by 13 % for a 1-month installation in Brasília.

How to optimize PV panel orientation?

We developed a new method to optimize the PV panel orientation. It consists of two main layers: the first layer calculates the optimal tilt angle for a chosen period by maximizing the predicted energy production. The second layer calculates optimal tilt and schedules when considering a reorientation scenario.

What is the rotavg and rotmax of a solar panel?

For the solar panel tilt angle of 50°, the mean and maximum values of the rotational time history curve are Rotavg = 1.63° and Rotmax = 4.86°, respectively. In contrast, for the solar panel tilt angle of 30°, the mean value is 0.025°, nearly approaching zero, and the maximum value is 2.82°.
