In addition, the prestressing force size of the flexible piece can only be adjusted by means of experience of an installer when the flexible photovoltaic support is installed, and the prestressing force is too large or too small due to the fact that the prestressing force is often caused by artificial judgment, so that potential safety hazards are generated in the operation process of the flexible photovoltaic support, and the service life and the operation stability are affected.
