NOTE: Items with * are required for any design or engineering, the rest is helpful but not necessary if you are in a hurry!
Address is used by the designer/engineer to verify wind and snow loading, please fill in at least the zip code
Pole Mount Model and Information:
Please select the pole mount model you plan to use and the solar module you intend to put on it so we can verify the specs.
Select the pole mount model you intend to install.
Telling us your solar module brand, part number, thickness and number of modules help us verify the mount you selected will work with the solar module you plan to use. Not mandatory, but it can help prevent expensive errors from simple assumptions!
Just for verification.

The higher the tilt the more the wind affects the array. This means the steeper the tilt the bigger the foundation has to be. Our standard screw adjuster can adjust from 10degrees to 90degrees in the field. We use the tilt you specify to do the foundation and wind calculations for your project.
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.
Wind speed to be used for foundation and pole calculations. Old code minimum for most areas was 90mph. New code is 105mph for some areas. Verify with a licensed design professional if uncertain.
Exposure B. 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.|D
Usually specified by area. May be determined by engineers using address if necessary. Minimal effect on foundation and minimal effect on rack unless winter tilt is set at less than 30degrees.
Choose the soil condition that best meets your site. The higher the number the bigger the foundation required.
1. Crystalline bedrock
2. Sedimentary and foliated rock
3. Sandy gravel and/or gravel
4. Sand, silty sand, clayey sand,
silty gravel and clayey gravel
5. Clay, sandy clay, silty clay,
clayey silt, silt and sandy silt
Please let us know what level of design/engineering you need for your project. If you choose to purchase engineering please add the matching item to your cart and purchase it through our online store after you submit this form.
We offer a complimentary foundation recommendation based on the latest ASCE and IBC codes. Some jurisdictions require a drawing stamped by an engineer for each location, and some require an additional calc package along with the drawing to "show" the engineers calculations and assumptions.
