6 FAQs about [Photovoltaic support pile foundation bending calculation]
What are the different types of photovoltaic support foundations?
The common forms of photovoltaic support foundations include concrete independent foundations, concrete strip foundations, concrete cast-in-place piles, prestressed high-strength concrete (PHC piles), steel piles and steel pipe screw piles. The first three are cast-in situ piles, and the last three are precast piles.

Is a PHC pile foundation a reliable support structure for heliostats?
A comprehensive design program is proposed based on field tests and numerical simulations, considering deformation and bearing capacity. The study confirms the reliability of the PHC pile foundation as a support structure for heliostats, aiming to offer valuable insights for practical applications.
How are pile foundations subjected to different magnitudes of load?
The pile foundations are subjected to different magnitudes of load as per the location of the solar trackers, i.e., exterior, interior, and far-interior, as shown in Table 1.1.
How to calculate end point bearing capacity of a pile?
and E s is the soil’s modulus of elasticity. This method’s correlations are the result of 24 large-scale field load tests of piles driven in sand. Hence, it is understood that the following correlation is applicable to piles present in similar conditions. In this case, the end point bearing capacity is formulated as: Q p = q’ · N q · A p (12)
How to measure the deformation and stress state of PHC piles?
However, due to the fact that the foundation part of PHC piles was buried in the soil, it was challenging to obtain the deformation and stress state through monitoring means. There was no direct test method available for measuring the deformation of short pile foundations beneath the ground.
