One Solar Utah prepared calculations for the roof trusses located at the shop at the referenced above. It
was assumed that the lateral seismic and wind loads acting perpendicular to the trusses were distributed to
the roof sheathing and into the walls and were not included in the calculations. The analysis was limited
to each single roof truss and did not include any analysis of the wall, footing, etc. The loadings and
analysis were in accordance with the following codes
1. 2015 International Residential Code
2. ASCE 7-10 Minimum Design Loads for Buildings and Other Structures
3. 2015 National Design Specification for Wood Construction
1. Dead Load
a. Roof Load 15 psf
b. Solar Panel 3 psf
2. Live Load 20 psf
3. Ground Snow Load 50 psf
4. Wind
a. 3 Second Wind Gust Velocity 115 mph
b. Importance Factor 1.0
c. Exposure C
5. Seismic
a. Site Classification D
b. Design Spectral Reponses
i. SDS 0.447
ii. SD1 0.222
c. Importance Factor 1.0
Based on the calculations of the existing trusses, the additional loading from the solar panels did not cause
any of the roof trusses to become overstressed.
