Unirac is not the solar, electrical, or building engineer of record and is not responsible for the solar, electrical, or building design for this project. Allowable spans and resulting point loads are subject to the following conditions: 1. Building Height ≤ 60.00 ft unless otherwise specified. 2. Roof Slope ≥ 1.2° 3. Maximum rail cantilever ≤ 1/3 of selected span. 4. Occupancy/Risk Category I to IV. 5. Basic Wind Speed: 85.00 mph - 190.00 mph (IBC 2018/ASCE 7-16). Wind Exposure: B, C or D. 6. Ground Snow Load: 0.00 psf - 100.00 psf. (Reduction can be input if this is acceptable with your local building authority). Results are based on uniform snow loading and do not consider unbalanced, drifting, and sliding conditions. 7. Dead Load ≤ 5.00 psf (includes PV Modules and Racking). 8. Maximum PV Module Length: 120.00". 9. Seismic: Installations must be in seismic site class A, B, C, or D as defined in IBC 2006/ASCE 7-05. 10. Intermediary Span Distances: Roof attachment point loads be reduced linearly if the installed distance between the attachments is less than the selected span. For example, if the spacing is half the amount shown in the results, then the point loads may also be reduced by half. 11. Spans greater than 96.00".: While our products are valid for greater spans in many instances, we do not recommend this mounting configuration. Typical residential roofs are not designed for the larger point loads that might result from such excessive spans and we recommend final design by a licensed professional engineer of responsible charge. Pitched Roof Solutions (Flush Mounted Solutions): Modules are parallel to the roof surface and within 10.00". of it. Allowable roof pitch: 1.2°-45°. (SM is not fire tested for sloped of < 2:12, please check with your AHJ if this is acceptable.) Building has a monoslope roof with a slope ≤ 3°, a gable roof ≤ 45°, or a hip roof ≤ 27°. INSTALLATION AND DESIGN PLAN Roof Area 1 Rail type is shown along with quantity, including fractional lengths of each. For example, SM RAIL 168" MILL 2x(1/2) refers to using 2 rail segments that are 1/2 the length of the 168" rail(2x84" segments) ROW - SECTION NO MODULES RAIL TYPE, LENGTH, QTY SPLICES ROOF ATTACHMENTS 1-1 9 • SM LIGHT RAIL 246" MILL 2 + 2x(3/4) 2 40 2-1 9 • SM LIGHT RAIL 246" MILL 2 + 2x(3/4) 2 40 3-1 9 • SM LIGHT RAIL 246" MILL 2 + 2x(3/4) 2 40 4-1 9 • SM LIGHT RAIL 246" MILL 2 + 2x(3/4) 2 40 Field adjustments must be made in compliance with guidelines found in the Solarmount Installation Guide.
