Once you get moved in, call the local PV installers in your area and get quotes. I installed my first in 2008 when only 200 watt panels were available. In 2019, I replaced them all with 370's. Now there are 400's. Get the highest capacity possible so you installed the lowest number of panels possible. This leaves you more geography/space to add more later to increase.
Ask for an inverter that has an EV charging option too. Such as Solaredge, it has a model that has an EV charging option.
And I would encourage you to request an inverter that is larger than your requirements. Example Solaredge 5,000, get the 7500 or 10000. Get more than you need. Will make adding more panels later cheaper as your inverter will already have the capacity.
And try to get it done this year before the 22% tax credit falls. And if you are doing batteries/energy storage at same time as panels, the battery system gets the tax credit too. Try to get all you can get installed this year. Batteries added later are a struggle to get IRS tax credit. You can also add 1 or 2 min PV panels later to qualify for tax credit on batteries if need be. Sounds sneaky but works.
I have two parallel systems. One earns me credit at the utility. The other has Powerwalls and charges them during the day. The house runs from the Powerwalls at night. Both systems have Solaredge inverters with EV charging. The extra power made during the day is used directly from the panels to charge the car. Only need one, but nice to have a back up. And a 50 amp circuit for charging.
Does N.C, have Net Metering Agreements so you can make juice during the day for credit, so you can buy/use it back at night when you charge?
