Solar Panel Exosure Criteria: Due to complex solar arrays, the software does not automatically dete rmine if a panel is exposed. The following criteria must be used by the designer to determine if a panel is considered 'Exposed'. If any one of these criteria are met then the panel is considered Exposed: 1) The distance to adjacent solar array or bui Iding edge 'd1' is > 4 ft [1.2 m] 2) The distance to adjacent panel 'd2' > 4 ft [1.2 m] Wind Pressures for Solar Panel(s) per Sec 29.4.4 All wind pressures include a load factor of 0.6 Zone Exposed Ge Ge GCp GCp_Neg GCp_Pos p p Uplift Down Fig Uplift Down Uplift Down ----------- ------ ----- -------------- ------ - 1 Yes 1.500 1.000 30.3 - 2B - 1.893 0.453 - 63.56 10.14 2e Yes 1.500 1.000 30.3 - 2B - 1.893 0.453 - 63.56 10.14 2n Yes 1.500 1.000 30.3 - 2B - 2.498 0. 453 - 83.08 10.14 2r Yes 1.500 1.000 30.3 - 2B - 2.498 0.453 - 83.08 10.14 3e Yes 1.500 1.000 30.3 - 2B - 2.498 0.453 - 83.08 10.14 3r Yes 1.500 1.000 30.3 - 2B - 2.968 0.453 - 99.68 10.14 1 No 1.000 1.000 30.3 - 2B -1.893 0.453 - 42.37 10.14 2e No 1.000 1.000 30.3 - 2B -1.893 0.453 - 42.37 10.14 2n No 1.000 1.000 30.3 - 2B - 2.498 0.453 - 55.92 10.14 2r No 1.000 1.000 30.3 - 2B - 2.498 0.453 - 55.92 10.14 3e No 1.000 1.000 30.3 - 2B - 2.498 0.453 - 55.92 10.14 3r No 1.000 1.000 30.3 - 2B - 2.968 0.453 - 66.45 10.14 Notes: Zone = Zone based upon 'GCP Fig' Exposed = Exposed panel per Eqn 29.4 -6 Ge = Factor per Eqn 29.4 -6 GCrn_nom= Nominal press coeff per Fig 29.4 GCrn = Gp*Gc*Ge*GCrn_nom [Eqn 29.4 -6] p = qh*GCrn [Eqn 29.4 - 5] Area = Area of Zone is based upon area of one panel: 22.44 sq ft + Pressures Acting TOWARD Surface - Pressures Acting AWAY from Surface Origin of X/Y system is at the geometric center of the build ing The array shall be located 2*h2 (1.000 ft) from roof edge, a gable ridge, or a hip ridge.

The unique water seal design is both elevated and encapsulated, delivering redundant layers of protection against water intrusion. In addition, the twist -on Cap perfectly aligns the rail attachment with the lag bolt to maximize mechanical strength. Twist -On Cap FlashFoot2's unique Cap design encaps the lag bolt and locks into place with a si twist. The Cap helps FlashFoot2 deliver superior structural strength, by aligning the rail and lag bolt in a concentric load path. Single Socket Size A custom -design lag bolt allows you to install FlashFoot2 with the same 7/16" socket size used on other Flush Mount System components. Tech Brief raw Three -Tier Water Seal FlashFoot2's seal architecture utilizes three layers of protection. An elevated platform diverts water away, while a stack of rugged components raises the seal an entire inch. The seal is then fully-encapuslated by the Cap. FlashFoot2 is the first solar attachment to pass the TAS-100 Wind -Driven Rain Test. Water -Shedding Design An elevated platform diverts water away from the water seal.
