Sirius Environmental have installed an innovative solar panel ground mounting system at Stormy West landfill site in South Wales. The Tree System design was developed in Italy and following extensive trials has been deployed at full scale by Sirius in order to demonstrate the effectiveness of this system in solar deployments on landfill sites.



The system involves a surface mounted racking system which is secured to the ground using a four pin anchor system which provides stability against wind loading whilst limiting the installation works to the shallow soil horizon without affecting the integrity of the landfill capping system.

The successful installation involved detailed site investigation to determine soil depths and the installation of appropriate anchor lengths to provide adequate holding down force which was proven through a number of pull-out and lateral loading tests.

Sirius Environmental staff undertook the site investigation, installation and pull out test works together with the structural and uplift calculations required to prove the system. Stormy West Landfill solar project is being developed as a 5MW solar farm by Sirius Renewable Energy.
