Installed prices in New Jersey by size

At half load, the figures use New Jersey fuel prices. Generac gives a fuel table for each model it sells. Its 18 kW and 24 kW units, and the 26 kW unit, are rated to use no more fuel each hour than the next smaller one, so what you burn per hour doesn't move in step with kW.
