Ballast involves adding weight to the solar substructure to stabilise it and prevent it from moving – or even blowing away – in strong winds. Ballast is typically added by applying special weights or by anchoring the construction to the ground. The precise amount of ballast required depends on various factors, including wind load, roof pitch and the specific design of the substructure. We will work with a structural engineer to draw up a tailored ballast plan for your roof structure.
