My 3 series panels on the roof have 62' total of 10 gauge wire to the controller resulting in 0.4% voltage drop which is very low. ie The panels on the ground could be about 31' from the controller.
You say your panels are SERIES. That is exactly what I am trying to accomplish. The weatherproof PWM controller that Renogy sells can not handle the panels in series, only in parallel. That is why I am wanting an MPPT controller.
And series panels with bypass diodes and a MPPT have better shade tolearance than than parallel panels. 12V panels may/may not have bypass diodes and 24V panels certainly will have bypass diodes. Disclaimer: This topic is often not understood.
