The HTR Solar Triple-Post Fixed-Tilt System is designed for ground-mounted solar PV projects requiring a 4 in Portrait (4P) module configuration.
With four modules arranged in portrait across the table slope, the resulting rafter is considerably longer than those used for smaller module configurations. The triple-post system introduces an intermediate support between the front and rear posts, reducing the effective rafter spans and helping control bending, deflection and connection forces.
Distributing the structural actions between three support lines also helps manage the compression, uplift and lateral reactions transferred into the foundations. This creates a stable structural arrangement while allowing the rafter and post sections to be selected more efficiently for the applicable project loads.
Our engineers consider module dimensions, table geometry, tilt angle, wind and snow actions, topography, ground conditions, corrosion environment and required design life when developing the final mounting arrangement.
By combining in-house structural engineering with flexible UK manufacturing, we can coordinate the posts, rafters, stringers, bracing, connections and foundation interfaces as one complete project-specific solution.
