4.0 Design Loads - Dead: <br />There are two categories of dead load used to perform the structural analysis of the PanelClaw racking system; Dead Load of the Array (DLA) and <br />Dead Load of the Components (DLC). <br />DLA is defined as the weight of the entire array including all of the system components and total ballast used on the array. <br />DLC is defined as the weight of the modules and the racking components within an array. The DLC does not include the ballast used to resist loads <br />on this array. <br />4.1 Dead Load of the Arrays: <br />Array Information Results <br />Sub- <br />Array <br />Name <br />Number <br />of <br />Modules <br />DLC <br />(lbs.) <br />DLA <br />(lbs.) <br />DLC <br />(lbs.)/module <br />Sub- <br />Array <br />Area <br />(ft.^2) <br />Sub-Array <br />Roof <br />Pressure <br />(DLC) (psf) <br />Sub-Array <br />Roof <br />Pressure <br />(DLA) (psf) <br />Max <br />Allowable <br />Pressure on <br />Roof (psf) <br />Acceptable? <br />1.1 22 1,600 1,600 73 701 2.28 2.28 6.00 Yes <br />1.2 54 3,888 3,888 72 1,731 2.25 2.25 6.00 Yes <br />1.3 162 11,380 11,380 70 5,071 2.24 2.24 6.00 Yes <br />1.4 176 12,264 12,264 70 5,517 2.22 2.22 6.00 Yes <br />1.5 160 11,153 11,153 70 5,015 2.22 2.22 6.00 Yes <br />1.6 142 9,889 9,889 70 4,452 2.22 2.22 6.00 Yes <br />1.7 140 9,778 9,778 70 4,397 2.22 2.22 6.00 Yes <br />1.8 118 8,254 8,254 70 3,710 2.22 2.22 6.00 Yes <br />Total:  974 68,206 lbs.68,206 lbs. <br />*Racking component weight range between 10 to 12 pounds per module <br />Table 4.1 - Array Dead Loads and Roof Pressures <br />07/09/2024 <br />8 <br />PanelClaw, Inc., 1600 Osgood Street, Suite 2023, North Andover, MA 01845 <br />(978) 688.4900 - www.panelclaw.com
