SOTO, P.E. 83104 AN ENGINEER LICENSED PURSUANT TO CHAPTER
471, CERTIFY THAT THE PV ELECTRICAL SYSTEM AND ELECTRICAL
COMPONENTS ARE DESIGNED AND APPROVED USING THE
STANDARDS CONTAINED IN THE MOST RECENT VERSION OF THE
FLORIDA BUILDING CODE.
APPLICABLE CODES: 2017 FLORIDA BUILDING CODE 6TH, ASCE 7-10
MINIMUM DESIGN LOADS FOR BUILDING AND OTHER STRUCTURES,
NEC 2014 ELECTRICAL CODE
ALL WIND DESIGN CRITERIA AND PARAMETERS ARE FOR HIP AND
GABLE RESIDENTIAL ROOFS, CONSIDERING FROM A 7° TO A MAXIMUM
27° (2/12 TO A MAXIMUM 6/12 PITCH ROOF IN SCHEDULE. ALL
RESIDENTIAL ROOFS SHALL NOT EXCEED 30'-0" MEAN ROOF HEIGHT.
ROOF SEALANTS SHALL CONFORM TO ASTM C920 AND ASTM 6511,
AND
IS RESPONSIBILITY OF THE CONTRACTOR TO PILOT FILL ALL HOLES.
CONTRACTOR SHALL ENSURE ALL ROOF PENETRATIONS TO BE
INSTALLED AND SEALED PER 2017 FLORIDA BUILDING CODE OR
LOCAL GOVERNING CODE.
ALL WIRING METHODS AND INSTALLATION PRACTICES SHALL
CONFORM TO THE NATIONAL ELECTRICAL CODE (NEC) 2014, LOCAL
STATE CODES, AND OTHER APPLICABLE LOCAL CODES. MEANS
SHALL BE PROVIDED TO DISCONNECT ALL CURRENT CARRYING
CONDUCTORS OF THE PHOTOVOLTAIC POWER SOURCE FROM ALL
OTHER CONDUCTORS IN THE BUILDING. CONNECTORS TO BE
TORQUED PER DEVICE LISTING, OR MANUFACTURERS
RECOMMENDATIONS. NON-CURRENT CARRYING METAL PARTS SHALL
BE CHECKED FOR PROPER GROUNDING.
REQUIRED SAFETY SIGNS AND LABELS SHALL BE PERMANENTLY
ATTACHED BY ADHESIVE, OR OTHER MECHANICAL MEANS, LABELS
SHALL COMPLY WITH ARTICLE 690 VI OF THE NEC 2014 OR OTHER
APPLICABLE STATE AND LOCAL CODES. SEE LABELS AND MARKING
PAGE FOR MORE INFORMATION.
RACKING ROOF MOUNT SYSTEM SHALL BE INSTALLED FOLLOWING
MANUFACTURERS INSTRUCTION SPEC'S, INCLUDING ALL GROUNDING
WEEB CLIPS, GROUND LUGS, AND RAIL SPLICE KITS FOR ELECTRICAL
CONTINUITY.
MECAWIND TOOL IS BASED ON THE C&C WIND LOADS FOR ENCLOSED

Lag Screw Installation Guidelines
1. Determine location for the Mount on roof by
drilling through the center of truss from bottom with
5/32" drill bit.
2. Mark mounting holes for Mount on
underlayment. Mounting holes should be centered
on the trusses.
3. Drill 15/64" pilot hole.
4. Apply sealant to bottom of Mount.
5. Place Mount over roof underlayment with holes
in roof.
6. Apply sealant to bottom of Mount, apply sealant
to lag screws and fasten Mount securely to
trusses.
7. Apply additional sealant to top assembly to be
sure all penetrations are sealed.
Notes: (1) Thread must be embedded in the side grain of a Trusses or other structural
member integral with the building structure.
(2)Lag Bolts must be located in the middle third of the structural member.
(3)These values are not valid for wet services.
(4)This table does not include shear capacities. If necessary, contact a local engineer to
specify lag bolt size with regard to shear forces.
(5)Install lag bolts with head ad washer flush to surface (no gap). Do nor over-torque.
(6)Withdrawal design values for lag screw connections shall be multiplied by applicable
adjustment factors if necessary. See table 10.3.1 in the American Wood Council NDS
for Wood Construction.
ASCE 7-10 Velocity Pressure
qz10 = 0.00256Kz Kzt Kd V2
Where:
qz10 = ASCE 7-10 velocity pressure evaluated at mean roof height (psf)
Kz = velocity pressure exposure coefficient
Kzt = topographic factor
Kd = wind directionality factor
V = basic wind speed (mph) from ASCE 7-10 maps referred to as ultimate wind
speed maps in 2012 IBC.
As an example, for an array having an area of 158.04 sq.-ft., the total uplifting
(resultant) force acting on the array would be -39.1 psf x 158.04 sq. ft. = -6,179.364
lb. Knowing this resultant force, the design engineer can now determine the number
of attachment points and the size of the mounting hardware necessary to safely
carry this load.
Live Loads:
Live loads associated with photovoltaic systems are usually assumed to be
distributed uniformly and are small, on the order of 4 psf or less.
