Hi All!
I am trying to setup a solar system in the coming months mostly on my own (setup of ground mount, mounting the panels, sourcing the parts, etc). I plan on getting 2 EVs and hopefully a powerwall (or whatever for storage) in the future. More people will live with me at home in the future as well. I consume about 30kwh a day on my own and its only going to increase with time.
I wanted to get as many panels as I could accounting for future load requirements. Nothing here is set in stone which is why im coming back on here to get advice from you guys. Keep in mind I am still new to this so be gentle.

I have some questions:
1) is my "design" feasible ?
ground mount with wiring going through existing buried conduit all the way some 230ft to the closet where i hope to place the inverters then on to the main panel.
2) if you had to chose between these two which would you choose? (pretty sure i have 3-phase as my meter says 3W on it)
Not sure if I would even be allowed to use the 30kw commercial inverter, but its cheaper than 2 sunny boys with double the capacity, the only issue being lack of SPS (solar power during grid down scenario)
a) 30kwh (no SPS) SMA SUNNY TRIPOWER 30000TL-US-10 = $2,437.50
b) 15.4kwh (2k watt SPS, grid down support) SMA SunnyBoy 7.7-1SP-US-40 = $2939.24

3) if you had 40-45 panels knowing what you know given the scenario what would be your panel wiring strategy be?
Electrical specifications:
Module Watts STC: 345 Watts
Max Power Voltage (Vmpp): 38.6 Volts
Max Power Current (Impp): 8.94 Amps
Open Circuit Voltage (Voc): 46.1 Volts
Short Circuit Current (Isc): 9.44 Amps
Max System Voltage: 1500V (IEC/UL) or 1000V (IEC/UL)
Series Fuse Rating: 30 Amps
Module Efficiency: 17.39%
4) In Miami-Dade, where i live, you are required to submit a design and hire a certified electrician to do all the electrical wiring so I will have to hire someone for that, any advise for finding the right people to do that part ?
I have a quote for around 6k that includes the design, permit submitting , electrical connecting - basically all the things I cant do.
5) Is it true that you have to get a certain type of insurance if you go over a 10kw system before the electrical company will give you the netmeter ??
The parts run about $14k-16k for a grand total of $20-22k for a 14.5 - 15.5 Kw system.
Do you guys think it's decent pricing? I don't even know if I would save much money over having someone do everything themselves but I was quoted 20k for a 9Kw system in the past so i thought 20-22k wasnt too bad given the extra 6kw I would be getting.
Any advice is welcome. Thank you in advance.
