Revision to Stamped Drawing or Calculation

The ground mount layout is 2 modules (portrait) x as many required. The quantity of modules should be an even number.

Our standard screw adjuster can adjust from 10° to 90° in the field. We use the tilt you specify to calculate the foundation and wind calculations for your project. The larger the tilt, the larger the wind load on the array and reduced snow load on the array.

Our ground mount has a fixed tilt. The larger the tilt, the larger the wind load on the array and reduced snow load on the array.

This is the clearance at the tilt specified above between the ground and the south edge of the array. The lower the clearance the shorter the support post and the smaller the foundation required.

This is the clearance at the tilt specified above between the ground and the south edge of the array. The lower the clearance the shorter the support post and the smaller the foundation required.

Address is used to verify wind speeds, snow loading, and local jurisdiction requirements.

To find the required design wind and snow loads at the installation site, you can reach out to the local jurisdiction or you can utilize this website (https://hazards.atcouncil.org/#/) to find the design requirements according to the International Building Code. Array mounts are considered Risk Category I structures

Exposure B shall be assumed unless the site meets the definition of another type of exposure. Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger. Exposure C. Open terrain with scattered obstructions, including surface undulations or other irregularities, having heights generally less than 30 feet (9144 mm) extending more than 1,500 feet (457.2) from the building site in any quadrant. This exposure shall also apply to any building located within Exposure B-type terrain where the building is directly adjacent to open areas of ExposureC-type terrain in any quadrant for a distance of more than 600 feet (182.9 m). This category includes flat open country, grasslands and shorelines in hurricane-prone regions. Exposure D. Flat, unobstructed areas exposed to wind flowing over open water (excluding shorelines in hurricane-prone regions) for a distance of at least 1 mile (1.61 km). Shorelines in Exposure D include inland waterways, the Great Lakes and coastal areas of California, Oregon, Washington and Alaska. This exposure shall apply only to thos buildings and other structures exposed to the wind coming from over the water. Exposure D extends inland from the shoreline a distance of 1,500 feet (460 m) or 10 times the height of the building or structure, whichever is greater.

Choose the soil condition that best meets your site. 1. Sedimentary and foliated rock 2. Sandy gravel and/or gravel 3. Sand, silty sand, clayey sand, silty gravel and clayey gravel 4. Clay, sandy clay, silty clay, clayey silt, silt and sandy silt
