Unirac 500026/50 Top of Pole Rack 30"/1 US42

Each PV PoleTop™ installation is rated as a full system by UniRac's proprietary engineering analysis software, which factors in rack model number, type and number of PV modules, array tilt angle, and mounting pole characteristics.

PV PoleTops are the only poletop line in the PV industry to offer the durability of all-aluminum components.

All use installation-friendly SolarMount™ rails for great strength over long spans.

D e s i g n W i n d P r e s s u r e s

To ensure the structural integrity and to provide the installer with an accurate wind pressure rating, we have thoroughly computer analyzed and laboratory tested our PV PoleTops™. The resulting Design Wind Pressures— maximum allowable wind pressure in pounds per square foot (psf)—appear after model numbers on the sizing chart on page 2 of sizing chart below.

Each rating applies to the entire system, which includes the PV modules and the mounting pole in addition to the PV PoleTop. Thus, we never rate above 50 psf (the manufacturers’ typical rating for the PV panels alone). Where our rating is below 50 psf, it is in most cases because our analysis predicts that the mounting pole will buckle above the rated load. The ratings on our sizing chart were calculated based on the following assumptions:

• Make, model, and quantity of modules as indicated on the sizing chart;
• A tilt angle of 40 degrees from the horizontal;
• A mounting pole of Schedule 40 steel pipe, 5 feet above ground for Series 5000 to 5003, 6 feet for Series 5004;
• Installation performed in accordance with applicable installation instructions.
