It would be interesting to know what the net gain is. Obviously there is the materials and labor cost of installation, but then you also have the battery cost. I assume most of the trucks are out during the day, so you need batteries to store the generated power until the truck can be charged at night.
And does Amazon own the warehouses outright, or do they lease them?

Why not just double your fleet size instead?
That's a bit extreme, but this is the kind of optimization that your bean counters are good at. You probably don't need to double your fleet but just keep enough that you can shift the consumption curve or take advantage of price changes.
