So I noticed something a little weird with this; I had my entry way covered in modular solar panels to power my turrets, but the turrets couldn't actually shoot anything, because the solar panels were blocking their line of sight. It looks like that was just because fillPercent was set to 1 in the thingDef. I set it to .025, and now I can actually shoot past them, with a small chance of accidentally hitting each panel I'm shooting over. Attached is a copy with that modification, for your convenience if you want to use it.
