6 FAQs about [Photovoltaic support pile test requirements]

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.

How high should a pile be for a photovoltaic plant?

In any case, for the types of piles that are being used in the foundations of photovoltaic plants, it is recommended that the height of load application will be in order of 1,0 m and in no case exceeding 1,5 m.

What are the requirements for a test pile?

The area surrounding the test pile must be cleared of pile spoil, slurry and rubbish. A properly designed level platform of sufficient plan dimensions to support the testing equipment safely and with suitable access for operatives, transport vehicles and lifting plant must be provided.

Why is Pile Load testing important?

For simple structures on a site where the ground conditions are well understood and there is pile test data from adjacent sites that have used similar piling solutions, then the risks are low and pile load testing can usually be restricted to routine checks for compliance or can even be omitted.

How a load is applied to a pile?

The application of the load to the pile can be carried out either through the construction of a loading frame, or by employing heavy machinery as a reaction, applying the load with a pulley system or hoist in the case of axial tensile load tests and lateral load tests, or with a hydraulic jack in the case of compression tests.

How many people are required to perform a pile load test?

This may require a minimum of two people present on site during the duration of the test. Pile load tests harness significant amounts of energy and if this energy is not controlled in a safe manner it presents a significant safety hazard. Failures can occur rapidly with little or no warning.
