6 FAQs about [Photovoltaic support pile test report]

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.

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 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.

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.

Is FEA simulation more conservative than pile load testing?

Figure 5 showed that when the compression load is less than 10 kN, the FEA simulations generated larger deformation than the real data of pile load testing, which implies that in this case, FEA simulation will be conservative than pile load testing to interpret the compression skin friction and end bearing capacity.
