I think that is a great idea.

Too many people have unrealistic expectations of the grid, back-up power systems, and what power can be reasonably produced. We cannot expect to generate whole house AC and heat, hot water, clothes washing and drying, 24/7.

A smallish array of 7-10 panels of 300 watts each would allow you, in the event of a grid collapse for whatever reason, to sustain (on a rotating basis) refrigeration (chest freezers with thermostatic controls are a good substitute), limited task lighting, air circulation, small device charging, entertainment, communications, food prep, etc.

The system, without battery back-up would inherently be limited to mostly sunny to clear days, during daylight hours. Depending on how far north you are, this could be anywhere from a few hours of usable light per day, to more than 12 hours.

The solution would seem to be off the grid small systems that will meet the needs you have calculated that you require. The best generators out there will not run for long when fuel deliveries stop. Your freezer does not need to run all day long to keep your food cold. If you have 3,000 watts of tracking panels with the associated inverters, charge controllers, connectors, cabling, etc., perhaps with a small number of deep-cycle batteries or a small LP/NG generator for emergency power after hours or during extended overcast conditions would put you ahead of probably more than 95% of your fellow citizens.

Anybody with a deal on a Honda EU2200i, feel free to clue me in.

Just my .02, YMMV.
