Flexible solar panel pressure measurement

4 FAQs about [Flexible solar panel pressure measurement]

What is a good wind pressure coefficient for PV panels?

In the leeward direction from the 210°–330° wind direction, the uneven wind pressure coefficient falls below 1, varying between 0.475 and 0.961. This indicates a higher wind pressure coefficient for the upper row of PV panels than for the lower row.

Can field wind pressure measurements be used for tracking photovoltaic arrays?

While progress has been made in wind tunnel testing and numerical simulation of tracking photovoltaic arrays, several key phenomena still necessitate thorough investigation via field wind pressure measurements.

What is a flexible photovoltaic (PV) system?

Author to whom correspondence should be addressed. Photovoltaic (PV) system is an essential part in renewable energy development, which exhibits huge market demand. In comparison with traditional rigid-supported photovoltaic (PV) system, the flexible photovoltaic (PV) system structure is much more vulnerable to wind load.

What is the wind speed profile of a solar panel?

The Wind speed profile followed power law with exponential 0.15 as a characteristic index of open terrain. The measured wind speed of the upstream solar panel about 5 cm in height is the reference wind speed at which 7.3 m/s and 13 % for wind velocity and turbulence intensity (TI) at panel height respectively.
