Racks on roof: Ironridge has an app that will compute the loading for their product. If you have rafters you may be fine using that. I made a little spreadsheet with their calcs to paste into PPT. Sometimes with trusses modifications are needed for lift. I have designed for both.

Electrical: One needs to do the calcs to decide on the wire size, voltage drop, etc.

Were these stamped drawings for $250?

my god if PE's are stamping drawings for 250 bucks I don't want to live in this country anymore

Turns out I need stamped drawings and structural for this municipality. They are accepting electronically stamped and it’s costing me $650 for both sets. I print them.
