I bought 40 solar panels 2 years ago from Santan Solar that came out to about $130 including shipping and tax. These were 450 W panels. Looks like they now have 400 W panels for $145 + shipping/tax.

I know you didn't ask for it, but in case it's helpful to anyone, here's what I spent (this was all DIY installed):

- $4200 for solar panels (I only kept 33 of the panels and resold the other 7, so this is my net cost).

- $4850 for EG4 18KPV inverter.

- $6800 for 2x EG4 14.3 kWh indoor batteries + conduit boxes.

- $1900 for EG4 GridBOSS.

- $1700 for Tigo optimizers (TS4-A-O + CCA + TAP).

- $825 for permitting.

- $2575 to redo some siding on my house because I hard to replace my meter box and main panel.

- $4000 for wire, conduit, junction boxes, PV DC disconnect, AC disconnect, meter box, main service panel, etc.

- $3200 for racking and roof stuff.

- $2000 for misc things, tools, etc.

Net (including 30% tax credit and 2% credit card cash back), I spent $21,228.47 for everything.
