I would really appreciate any input you guys could provide as this will be the biggest purchase I've ever made besides the home!

I have a south facing roof w/o any shading which is great, but it's not the biggest. I'm estimating it's around 900 sq ft. I received a few quotes and just want some thought as to the pricing and if I'm overlooking anything that I should be adding/removing before taking the plunge. Average home usage ~20kwh in the winter months, 35kwh in the summer, SCE TOU-D Prime, just bought used tesla Y which will likely charge 5-10kwh/day average with 15kwh/day on Sat/Sun. Tesla can mostly charge during the super off peak daytime hours 8AM-4PM

The best locally based company quote

$50k - 22 REC 460AA Pure RX, 1PW3 + 1 dc expansion, panel upgrade

-they say 10.1kW array producing 16,300kW/year

-option for $15k off with prepaid PPA but the more I have looked into this, the more I am leaning towards not going this route.…
