Orange County, CA - Permit Process, "Please upload calcs. Thank you"

[skyc]

Working on a 22 panel installation with Enphase microinverters, purchased a solar permitting package to assist with the permitting. I submitted my permit and received a note "Please upload calcs. Thank you". I've reached out to the company I purchased the permit PDF from as well as the person who sent me the notification from the county by haven't heard anything back yet. I wanted to see if anyone was familiar with this process and what specific calculations they may be looking for?

The plan has the following calculations in various parts

• Point load calculation for the array with weight per mount, per sq foot, wind uplift calculation.
• Calculations for current carrying conductors

Is this a rooftop installation using the expedited permit process?

It might be something like the example on page 26 here:

But if your county allows DIY they should be patient enough for you to simply ask them what they're asking for.

I think they may be requesting structural calculations and stamp.
