What is the optimal configuration for a photovoltaic panel array?

Under wind velocities of 2 m/s and 4 m/s, the optimal configuration for photovoltaic (PV) panel arrays was observed to possess an inclination angle of 35°, a column spacing of 0 m, and a row spacing of 3 m (S9), exhibiting the highest φ value indicative of wind resistance efficiency surpassing 0.64.

Do flexible PV support structures amplify oscillations?

The research explores the critical wind speeds relative to varying spans and prestress levels within the system. Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures.

How safe are flexible PV brackets under extreme operating conditions?

Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.

Does oblique wind affect PV panels?

The simulations indicate that, under identical wind speeds, the PV panel arrays exhibit superior capacity in mitigating the impact of oblique wind directions (45° and 135°), particularly noticeable at the forefront of the PV panel.

Does a flexible PV support structure exhibit a consistent response trend?

However, for mid-span acceleration, the wind suction condition results in greater values than the wind-pressure condition. Overall, it can be concluded that the flexible PV support structure exhibits a consistent response trend under both wind-suction and wind-pressure conditions. Figure 10.

What inclination angle should a PV panel array have?

We can then conclude that the optimal design for PV panel arrays should be an inclination angle of 35°, a column spacing of 0 m, and a row spacing of 3 m under low-and medium-velocity conditions, while panel inclination needs to be properly reduced under high-velocity conditions.
