6 FAQs about [Photovoltaic support test pile construction plan]

What is Pile Load testing in solar project?

Pile load testing is usually required and performed for H-pile foundations. Procedure of pile load testing in solar project is referenced to pertinent ASTM standards for conventional deep foundations under static axial tensile load and under lateral load.

How FEA compared with Pile Load testing for solar power projects?

Significant cost saving can be reached by carrying out pile load testing program for utility-scale solar power projects. Comparison between pile load testing and FEA indicates a general agreement in terms of axial compression, uplift and lateral load applications.

How many times a design load should a testing pile be?

Typically, the testing piles and installation methods shall be the same as production piles, and the maximum of the testing load shall be at least two times of the design loads.

Can Static Pile Load testing be used for solar power?

Two case studies for solar power can be used to illustrate static pile load testing and numerical simulations. The two projects were geographically located in Texas and California, and the proposed solar power facilities comprise 180 MW (ac)/243.42 MW (dc) and 60 MW (ac), respectively.

How many piles are needed for a solar project?

Solar projects require thousands of foundation piles to support trackers and panels. Typically, there are two stages at which load testing occurs: pre-design and construction. Because of the potential for variability in the type of reaction force utilized during pile load testing.

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.
