Recommendations for solar charge/controller
It appears a buddy of mind is going to donate two used 300 watt panels. They are rated at 30 volts with about 8 amps open voltage (he got them for a song - used I should say) We’ve been out in t...

Voltage drop is related to wire size and amps flowing. Putting the panels in series keeps the amps low. That gives you less voltage drop. However, since the VOC is 45.29v, be sure that the MPPT controller is good to at least 100v.
If you opt for parallel, then be sure the wire is heavy enough to be capable of carrying 20 amps.
ON EDIT: corrected some numbers. I had misremembered and put numbers for 3 panels.
