Will 1.25" conduit be ok for three strings of panels? Help with wire/conduit sizing?
Post Body

Panels are 410w up to 140w bifacial gain. Longi Hi-mo-5.

tesla powerwall Plus inverter

I'm thinking i'll do three strings of ten panels. two facing south and one facing more or less west.

The two south facing strings will be a max conduit run of about 100'. i have my trench dug (but not filled in) and currently have 1.25" conduit in it. will this suffice for both or even all three strings of panels? what size wire am i going to want to run from the panels to the inverter?

i'll have an electrician make the final connections but the more i can figure out and learn the better. am i figuring wire size based on 500 volts (10 panels @ 50v) and 13amps?
