Matt,
I took a look at this last week. The email must have gotten buried. See my notes below and attached helios.

Here are some basic rules-of-thumb for a flat roof (ballasted racking system):
Tilt – 10° for flat roof ballasted racking system
Azimuth – preferable SW (>180°, greater production)
Orientation – Horizontal (Landscape)
Racking – Fixed Tilt for flat roof (Flush Mount only for pitched roofs)
Setback – 6ft (per regulation)
Most of these adjustments were made to your design. I minimized the Setback to 5ft so we could fit one more panel on each row. There are two designs – one with keepouts (14.3kW) and one without (16.3kW). I’m not sure if with the re-roof if the three obstructions will be removed or remain there.
Let me know if you have any questions.

Subject: Ligon design
Would you please take a look at my preliminary design for Ligon Realtors? I would like to present this soon. He is redoing his roof, but it is pretty much flat.
Thanks…
