Only reason I can think they wouldn't be working is if they aren't fully built or the solar panels are in the shade.
No i had them in the light i dont know still a fun game my weirdness aside
Ive actually had this issue too, or at least it takes a turret that im standing away from that has a gen that isnt connected to anything besides it a while to target on occasion. Only with the Mk3 lasers ive seen this i gotta add
The gen was mk 3 solar in the sun
