4 PRE-JOB LAYOUT PREPARATIONS COMPLETE A SITE SURVEY 1. Obtain a set of roof plans or draw your own. 2. Verify that all dimensions are correct. 3. Note locations of roof penetrations (chimneys, vents, etc.) 4. Note the roof construction materials and locate framing member locations, paying attention to the spacing of the framing members. 5. Assess objects creating shading concerns DETERMINE THE SOLAR LAYOUT 1. It is recommended that your design be approved by a local building authority before beginning installation. Typically the rail span between supporting roof anchors is the most important design consideration. A solar checklist form and web resources are available at Solar checklist information must be provided along with jobsite information (preferably a roof plan) in order to provide the free solar array layout. For more details contact TRA Snow and Sun. 2. The solar layout should be designed with the following factors in mind that affect the structural design of the solar array: Windspeed Building height Snow load Exposure category Importance factor Roof slope/pitch 3. Other factors to be considered: Sun exposure Objects causing shading Proximity to inverters/electrical panels String capacities, etc. 4. Some local jurisdictions fire codes require walkways or edge clearances. Pre-Job Layout Preparations 4 / 35

10 MODULE COMPATIBILITY INSTALLATION MANUALS MODULE COMPATIBILITY Height Varies or SOLAR RAIL PLUS The heights of the End Clamp Assembly and Mid Clamp Assembly varies and are dependant on the solar module frame thickness. TRA Snow and Sun can customize End Clamps to fit any solar module. Module Compatibility 10 / 35

11 TRA Snow and Sun will provide an engineered layout for all Awning Mount Systems we design. An engineered plan will specify the spacing requirements per the project design criteria. As a standard, we design the Solar Rail Plus to be installed parallel or perpendicular to the rafters/trusses. Custom designs are available. Supporting wall attachments are required to be spaced, depending on local building requirements. The installer should check with the local building department to make sure the project complies with the specific code requirements for their locality. Customer is required to provide and verify that all design criteria is correct. AWNING LANDSCAPE (OPTION A) SYSTEM LAYOUT - LANDSCAPE TRA Snow and Sun s Landscape layout is installed with the mounting rails perpendicular to the wall. All wall attachments are mounted so flashing can be added to create a waterproof seal. Supporting wall attachments are required to be spaced, using either cross connectors or cross rails depending on local building requirements. The installer should check with the local building department to make sure the project complies with the specific code requirements for their locality. SYSTEM LAYOUT AWNING PORTRAIT (OPTION B) SYSTEM LAYOUT - PORTRAIT TRA Snow and Sun s portrait layout is installed with the mounting rails parallel to the wall. All wall attachments are mounted so flashing can be added to create a waterproof seal. Supporting roof attachments are required to be spaced, using either cross connectors or cross rails depending on local building requirements. The installer should check with the local building department to make sure the project complies with the specific code requirements for their locality. NOTES: Mid Clamp Assembly requires a ¾ inch gap between modules. TRA recommends 2 of Solar Rail Plus protruding at the ends of any string of panels for End Clamps and/or Grounding Lugs. Maximum rail span cannot exceed 6. The distance between roof attachments should be 6 apart or less. System Layout 11 / 35

13 Brick Step 1 WALL MOUNTS The Awning Solar Mounting Frame can be mounted on any wall type (concrete, frames, metal, brick, etc.). The fasteners are to be determined by the custpmer based on the material strength of the wall or wall framing material. MARK FRAME LOCATIONS TO PREPARE THE ROOF 1. Determine the location for the Frames on the vertical wall structure. (Refer to information gathered in the site survey and module manufacturer recommendations.) WALL MOUNTS 2. Mark the location using a chalk line to ensure a plum installation. Mark a horizontal line in the locations the Awning Frame is to be installed. 3. Layout Awning Frames at chalk line locations. 4. Mount the L-Base Brackets to the wall with customer determined fastener. 5. Spacing & locations is dtermined by TRA s Engineered Layout. Concrete NOTES: Spacing varies based on the size of the solar panel, wall framing spacing and the desired mounting angle of the system. Please refer to system drawings provided by TRA Snow and Sun for the correct spacing for your wall mounts. Studs Wall Mounts 13 / 35
