6 FAQs about [Solar photovoltaic power generation pile foundation model]
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.
How does a pile foundation handle a photovoltaic module?
When supporting the upper photovoltaic modules and other structures, the pile foundation must cope with the vertical load generated by these structures in addition to the lateral horizontal load caused by wind, waves, and other natural factors. This results in more complicated loading characteristics for the pile foundation.
Are fixed pile foundation systems better than floating offshore photovoltaic systems?
