Re: Proposed Photovoltaic Solar Panel Installation

ARCADIA,CA 91007
Dear Plan Reviewer:
Certification: I have reviewed the engineering testing reports for the racking and attachments to be used on this project
and I certify that the products are capable of supporting the code required loads and are suitable for this installation
when installed in strict compliance with the manufacturers printed instructions.
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.
If you have any questions relating to this matter,please contact me at your earliest convenience.Thank you.

Gravity Load Calculation Criteria
Structural Design Loads per ASCE 7-16
Dead Loads= 15 psf+2.6 psf(new solar panels)= 17.6 psf
Roof Live Load=20 psf
Ground Snow Load/Live Load=0 psf
Wind Load Calculation Criteria
Wind Loads per ASCE 7-16,Ch. 30.4
Design wind pressure determined by Eq. 29.4-7:
Zone 1 =-25 psf Roof Slope=23 degrees Roof Mean Height= 15 ft
Zone 2=-32.6 psf Basic Wind Speed=95 mph
Zone 3=-37.6 psf Exposure=C
Per section 2.4.1,ASD combo=D+0.6W:
Zone 1 =2.6 psf+0.6(-25 psf)=-12.4 psf
Zone 2=2.6 psf+0.6(-32.6 psf)=-17 psf
Zone 3=2.6 psf+0.6(-37.6 psf)=-20 psf
Check Attachment to Wood Rafter
Use 5/16 dia.Lag screw w/3" embedment into 2 in.wide roof rafter
Lag Screw Spacing: Lag Screw Tributary Area:
Zone 1 = 48"o.c. max Zone 1 =(48"o.c.max)^2/ 144= 16 SF
Zone 2= 48"o.c.max Zone 2=(48"o.c.max)^2/ 144= 16 SF
Zone 3= 48"o.c.max Zone 3=(48"o.c.max)^2/ 144= 16 SF
Lag Screw Forces: W=2661b/in(Table 12.2A,2015 NDS)
Zone 1 = 12.4 psf x 16 SF= 198 lb < W', OK Cd= 1.6(Table 2.3.2,2015 NDS)
Zone 2= 17 psf x 16 SF=272 lb < W', OK Ct= 1 (Table 2.3.3,2015 NDS)
Zone 3=20 psf x 16 SF=320 lb < W', OK W'=W x embed x Cd x Ct
W'=266 lb/in x 3 in.x1.6 x 1 = 1276.8 lb
