A solar piling structure is a foundation system in which steel piles or posts are driven or installed into the ground to support the mounting structure of photovoltaic modules.

The piling structure forms the foundation of a ground-mounted solar installation. It provides the structural support required to securely install solar module mounting systems while transferring loads safely into the ground.
Properly designed and installed piling structures help maintain structural stability, consistent module alignment and reliable performance throughout the operational life of the solar project.
