Voltage Loss - Impact of >3%
I'm working on some voltage loss calcs for a new array I'm contemplating, and the distance will be quite large. I'm looking to do 6 panels in series for ~220v, and then two series in parallel. The calculated total system voltage loss would be 3.75% with 6 AWG THHN wire. I understand that is over the magic 3% rule, but I wanted to understand what the impact is of being over 3%. What am I risking/sacrificing by being between 3-4%?
