Regarding the solar panel array installation on the above referenced project please note that an inspection was performed by a representative of the Architect/Engineer of Record,and analysis of the existing structure was conducted.There is adequate structural capacity for the installation of the array with the following recommendations: 1. The array will be installed on the existing roof.The roof framing is constructed of 2"x8"wood rafters @l6"o.c. spanning 13'-8"with 1/2"plywood sheathing.The new array(See Site map by contractor)will add 2.63 Lb./Sf. overall to the roof.The existing structure is sufficient to support the new loads associated with the additional weight& wind resistance.No additional structural support is required for the roof structure. 2.The attachment system shall be secured to the roof and shall be in strict compliance with manufacturers printed instructions.The attachment system shall be UL 1703 approved tested. Provide 6 mil.vapor barrier between dissimilar metals. Provide water tight gasket and sealant at all penetrations. Attachments shall follow panel rows as specified by the system manufacturer's installation manual.The panel angle shall match the roof slope.Reference summary table below: Roof Type: Tile Fastener Max Spacing(in.) Attachment System: "EcoFasten"Click Fitt Wind Zone I Wind Zone 2 Wind Zone 3 min. 5/16"x 3-1/2"long stainless-steel lags with a 48 48 48 Fastener Info: min.embedment of 2-1/2"into the rafters. 3. Solar Modules shall be UL-1703 rated. Refer to manufacturers specifications sheets. 4.Positive drainage of the system shall be so as not to void the existing roof warranty. 5. All aspects of the installation shall comply with the 2019 California Building Code,2019 California Electrical Code,with The American Society of Civil Engineers ASCE 7-16,2018 American Forest&Paper Association,Wood Frame Construction Manual,Local Municipal Code and All other codes and ordinances adopted by reference or enacted by law. 6.Please refer to the attached structural calculations.
