If you are going big go commercial grade panels even at retail prices by the pallet they are 2/3 the cost of Amazon.
Get someone with a TIN number and get wholesale price by the pallet worth. Half of the retail price point on a minimum two pallet order that’s 64 panels for around six grand. That’s 20 cents per watt with a25 year 80 cap life. 64 panels is a 28.8 kilowatt system and will power a HUGE home with dual A.C. Units roaring. Those panels are 75”*44” or 2.12 square meters no small coincidence as the 120 cells have an’m exactly 2 square meters area. If you laid them flat you won’t those 64 panels cover ~136 square meters or 1463 sq freedom units. Those panels will be tilted at an angle roughly equal to the latitude of instal. No need for acreage at all a fairly large home would already have the roof area facing south if not then cover the back yard deck, 3 car garage as well. Now you have a large system that even on overcast days are gonna put out 10 to 30% rates capacity. No need for copper wires outside you use aluminum wire just like every other commercial installation does.
You series wire your panels into groups of 8 for a working 277VDC at 13 amps or 3600 watt groups. 64 panels gives you eight groups. This is direct buried cable no conduct needed above or below ground. Cheap too and 50 amp @600V

You run them need eight 277vdc input 4000 watt pure sine inverters that will output either 3 phase (240/400)/50hz or split phase (120/240)/60Hz for the Americans. Here again with a TIN number those are in the 20 cents per watt capex.
Do the install with subcontractor labor and only use a licenced electrician for the breaker tie in and inverter to breaker connections. Your all in cost should be under 25 grand. You then have a full off grid capable power supply if you want to add in powerwalls Tesla will be happy to sell you some.
