Total installed cost in Texas by size

At half load, the fuel figures use Texas prices. Generac provides a fuel table for each of its models. Units at 18 kW, 24 kW and 26 kW are rated so that running an hour burns no more than the next size down, which is why hourly fuel use doesn't increase in step with the kW rating.
