Your situation is really not practical. Quite possible, but not practical.
If you're drawing 700 watts at 75% duty cycle during a 10 hour day, that's 5,250 watt/hours. You probably get around 3.5 sun hours per day in the winter in your area. That means you would need a 1,500 watt solar array not taking losses into account. Realistically, about 1,800 watts would be about right.
That assumes every day is perfectly sunny which may be the case in Nevada. Normally, you would want your battery bank to be able to ride thru one cloudy day at least. That would mean you would need 5,250 kWh of storage. If you do that with a 12v battery bank that's well over 400 Ah.
