METALLURGICAL STEEL POST DESIGN FOR SOLAR FARM FOUNDATIONS AND INCREASED GUARDRAIL DURABILITY

摘要

A high-grade post or pile system for the foundation of a solar array, which may facilitate the installation of a solar array rack in more corrosive soils. Such a post may also satisfy the need for a foundation able to resist ground forces, in particular the effects of wind on the exterior of the array, and may reduce problems with beam refusal. The post may be used in other applications such as guardrail posts. In contrast to existing posts for solar arrays, the high-grade post may be formed from higher-grade steel.
