RE: Evaluation of PanelClaw system
Project Name: South Coast Technology Center
CTS Job No.: 25-0242-3336
Per the request of Ryan Heil at PanelClaw, CTS was asked to review the
PanelClaw racking system with respect to the system’s ability to resist uplift and
sliding caused by wind and seismic loads.
Wind Evaluation:
PanelClaw has provided CTS with wind tunnel testing performed by CPP, Inc.
The system tested was the “clawFR 10 Degree” system. This system consists of
photovoltaic panels installed at a 10 degree tilt onto support assemblies. The
support assemblies consist of a support frame for the PV panels, wind deflectors
and areas for additional mass/weight as required for the ballast loads.
The wind tunnel testing was performed per Chapter 31 of ASCE 7-16. The
parameters of the testing were a flat roof system in both Exposure B and C on a
building with and without parapets. The testing has resulted in pressure and/or
force coefficients that were applied to the velocity pressure qz in order to obtain
the wind loads on the PV system. From the wind load results it is then possible to
calculate the ballast loads required to resist the uplift and sliding forces.
PanelClaw has provided CTS with the excel tool that was developed to obtain the
uplift and sliding forces. CTS has reviewed this tool and the wind forces obtained
to find that the amounts of ballast and mechanical attachments provided are
within the values required. Furthermore, CTS agrees with the methodologies
used to develop the uplift and sliding forces for the “clawFR 10 Degree” system
per the wind tunnel testing results.
Seismic Evaluation:
CTS was asked to review the PanelClaw system to determine attachments
required to resist seismic loading of the ballasted solar support system on the
roof of the existing building. Following CBC Load Combination 16-16 and ASCE
Section 2.4.5, the Dead Load value has been reduced by subtracting the vertical
component of the seismic forces (0.6*D - 0.14Sds*D). The contribution of friction
due to the component weight was not considered to resist lateral forces caused
by seismic loads per ASCE Section 13.4.
Utilizing this method, calculations have been provided for the number of
mechanical attachments that are required to resist seismic forces that are applied
to the system.

Conclusion:
Therefore, it has been determined that the system as provided by PanelClaw is
sufficient to resist both wind and seismic loads at this project.

To Whom It May Concern:
Per your request, we have reviewed the existing roof framing at the above referenced site. The
purpose of our review was to determine the adequacy of the existing structure to support the
proposed installation of solar panels on the roof as shown on the panel layout plan. Based upon
our review, we conclude that the existing structure is adequate to support the proposed solar
panel installation with the given geometry and weight restriction outline in this report.
The mechanical attachment for the PV ballast system is also designed in this calculation and can
be used if applicable.
The PV ballast system including requirements for blocks and mechanical attachments to resist
the wind and seismic forces (uplift, drag, lateral) to be designed by others. The design of the PV
ballast system is out of scope of this calculation.
If you have any questions, don't hesitate to contact.
Sincerely,
Arash Zandieh, Ph.D., P.E.

Roof Check
Methodology
The increased weight due to the ballast installation is reported in the table below. A maximum
uniform load of 6.21 psf is conservatively assumed for the ballast system and the existing roof
structure is evaluated. Ballast weight is evenly distributed on the roof members.
The following calculations show the increased load due to ballast installation is less than 5% of
gravity design loads and is less than 10% of the seismic design weight for the lateral load
calculation. Therefore, no further calculation is required, and the existing roof structure has
adequate capacity to resist the ballast-installed load.
PV load (psf) = 6.21
Area of solar panels (sqft) = 3347
Total weight (lbs) = 20782
Existing roof loads Gravity Check: Dead (psf)= 10
Live (psf) = 20
Snow (psf) = 0
Load pre-PV D (psf) = 10
D + L (psf) = 30
D + S (psf) = 10
D + 0.75 L + 0.75 S (psf) = 25
Governing load (psf) = 30
Load post-PV D (psf) = 16.21
D + L (psf) = 26.21
D + S (psf) = 16.21
Governing load (psf) = 26.21
Gravity load increase Load_postPV / Load_prePV = 0.87 OK
