Your general question is fair, but your math is wrong which exaggerates the difference.

10 Powerwalls: 140 kWh / $110k = 1.27 Wh/$ 1

40k truck: 98 kWh / $40k = 2.45 Wh/$

72.5k truck: 131 kWh / $72.5k = 1.81 Wh/$

That said, I would speculate the that base model is effectively being subsidized by the marketing team. Saying it "starts at under $40k" sounds a lot better than "starts at under $73k". Ford simply won't produce that model in high quantities and they also know people generally won't be buying the base model anyway.

Apparently 1/5 Lightning's are the $40k pro model for the commercial market. I wouldn't be surprised if Ford is selling at a loss, but it's more likely to get the foot in the door of electrifying work trucks and making sure companies are investing in electric infrastructure so that Ford can replace the other 90% of the companies fleet with electric at a profit.

The 72.5k truck only provides about 90 kwh at 9.6kw

90 / 72.5 = 1.24 Wh/$

Source is a footnote on Sunrun's site: "3When home is properly equipped and home transfer switch disconnects home from the grid. Based on 30kWh use per day using the F-150 Lightning with the extended range battery...." It requires the 80A charger which costs $4k + installation + the electrical upgrades to send 80A to wherever your charger is located.

It's incompatible with many solar systems too.
