I would like to re-iterate Damon's advice above, to keep KW and KWH straight. Can't have a useful discussion until the terms are consistently defined. A "watt" is a unit of power (energy per unit time), and a "watt-hour" is a unit of energy. And there is no such thing as "watts per hour" (nor per day). A watt-hour (not "per" hour) is the energy used by a 1-watt load (small night light) if it stays powered on for an hour. A kilowatt-hour is the same, for a 1000-watt load (portable electric space heater).
Atokatim wrote: "The peak is 4kWh but the average is 2.5 to 3. The usage chart I have gotten ranges between 55 to 92 kW per day." Those units are clearly reversed. That is because "per day" you use a certain amount of energy (KWH), while power (KW) is momentary.
The electric company charges you for cumulative energy (KWH), not instantaneous power (KW, unless you are an industrial user). Thus, for example, 55-92 KWH (not KW!) per day is (divide by 24 hours) 2.3-3.8 KW, or 2300-3800 watts, of instantaneous power, on the average, during the day.
To get that much power (say 3000 average watts) out of solar panels would take a much larger number of nominal panel watts, since the sun is not shining all the time. In a good solar location (Arizona) you'd need about 12,000 watts worth of panels, while in a poor location (England) you would need to double that (or worse). That's a lot of panels. The area covered by 12,000 watts of panels is approximately 1000 square feet, and their installed cost these days would be at least US$20,000 (just for the panels, without wiring, inverters, etc). If half the roof is south-facing (in N. hemisphere), and the house has two floors, we're talking about completely covering that half-roof on a 4000 square foot house.
First Economize, Then Solarize.
