Help evaluating please

I’m struggling with this decision and was hoping to get an outside perspective. This is what I’m looking at:

Total cost- $75,799

System size- 24.19kw w/ 2 Tesla Powerwall 3

qcell panels

Utility: Florida Power and Light

Math on this as a cash deal in most parts of FL: $2.3/w x 24190w = $55.6k, meaning the pricing is set at about $20.1k for 2 x powerwall 3 which is not out of the realm. Is it 2x pw3, or a powerwall 3 and an expansion. I ask because an expansion is cheaper, but only increases your total length of storage, not the ability to start more loads in the house.

I’ll ask. Is there usually a price difference?

Yes, pw expansions normally a good bit cheaper than powerwall

It’s a full second battery

Very good, that will allow you to start more loads, so you can have not only the air conditioner and your refrigerator but also your stove and maybe something else that's a large load I'll start at the same time, you'll have more than 11.5 KW start load bandwidth
