The information used to evaluate this structure was gathered by Project Solar on behalf of Right Angle Engineering. The roof structure consists of pre -manufactured steel frame spaced at 24" on center. The roof material consists of corrugated metal. The design criteria used to analyze this structure are listed above and included with this letter. The adopted building codes in this jurisdiction are: the 2020 Florida Building Code, the 2020 Florida Existing Building Code, and ASCE 7-16. Florida Existing Building Code (FBC) 2020 section 807.4 indicates that alterations to an existing building that results in less than a 5% increase in the total stress may be performed without a structural evaluation of the existing building. As demonstrated in the attached calculations, the additional weight of the solar panels will be less than 5% increase in the gravity loading and the stress on the existing roof framing. Based on our assessment we have determined that the existing roof framing will safely and adequately support the additional loads imposed by the solar panels without reinforcement. In order for the loads to be evenly distributed, the roof attachments should be staggered and spread evenly throughout the panel array. Attachment points should be spaced at a maximum of 48" on center. The racking system should be installed per the manufacture's specifications. There should be a minimum of 148 S5 Protea Bracket attachment points to the roof. Waterproofing around the roof penetrations is the responsibility of others. Right Angle Engineering assumes no responsibility for improper installation of the solar panels. Regards, Ar No 39045 '� k Robert D Sin) the.

All system types that feature the UFO family —Flush Mount, lilt Mount and Ground Mount —are fully listed to the UL 2703 standard. UFO hardware forms secure electrical bonds with both the module and the rail, resulting in many parallel grounding paths throughout the system. This leads to safer and more reliable Installations. Stopper Sleeve The Stopper Sleeve snaps onto the UFO, converting it into a bonded end clamp. Bonded Splice " Each Bonded Splice uses sell -drilling screws to form a secure connection. No bonding strap needed. UFO Family of Components Grounding Lug A single Grounding Lug connects an entire row of PV modules to the grounding conductor. Universal Fastening Object (UFO) The UFO securely bonds solar modules to XR Rails. It comes assembled and lubricated, and can fit a wide range of module heights. Bonded Attachments The bonding bolt attaches and bonds the L-fool to the rail.
