Generators are not my specialty, so I can't help you there, but I can show you the math for the solar and batteries, which does in fact line up with the numbers SunKing gave you.
If you are thinking 35kwh a day, I'm guessing 5 sun hours for worst case in Dec, then for the array, 35,000Wh / 5 sun hours / .67 system inefficiencies = 10,447W of solar / 280W SolarWorlds = 38 panels.
35,000Wh / .92 inverter inefficiencies /.5 (50% DoD) x 2 days autonomy x 1.11 (temp compensation for 60F) = 169kWh / 48V = 3519ah 48V battery bank. I know you said it's always sunny, so you may not think you need the 2 days autonomy, but what that also does for you is most days you'll only use 25% of your battery, which will make them much happier than 50% every day.
It's worth it to think of other ways to fuel your heat needs. You can drop this down dramatically, and make it more practical and affordable.
