Frequently Asked Questions
What is EPA (Effective Projected Area)?
EPA is the area of a component projected perpendicular to the wind direction, multiplied by a shape factor. It's used to calculate wind force on each component mounted on the pole.
How is the safety factor calculated?
The safety factor is calculated as the ratio of the steel's yield strength to the calculated stress at the critical section (base of the pole). A minimum SF of 1.5 is recommended for safe design.
What does deflection ratio mean?
Deflection ratio is the ratio of pole tip deflection to pole height, expressed as a percentage. The recommended limit is 2.5% to ensure structural stability and lighting performance.
What components can I configure?
You can configure Solar Panels, Luminaires, Battery Boxes, and Arms. For each component, you set dimensions, shape factor, quantity, and mounting height for accurate wind load calculation.
