You can get an XT-60 to MC4 (solar connectors) adapter for less than $10. 100W solar panels can be had for $80 or less. You can connect them in series/parallel to get whatever voltage/amperage you need. Most of those 100W panels will be around 18V. 3 in series to get 54V will give you up to 300W of power at their max of 5.5A. Given the limits of the solar input on this, you can reasonably run 3-4 sets in parallel, giving you between 900-1200W. Maxing it out at 1200W from solar panels would cost less than $1000 (12 panels at $80 = $960), and even that is far more than most people would need or even bother with.

Microwave for a couple hours
TV for 40 hours
desktop computer for 10 hours
laptop for 4 hours
refrigerator should go for WAY WAY more than 4 hours. An average fridge is 1-2KWh per day so this should power a fridge between 4-8 days.
With respect to recharging, obviously you need to consider the AVERAGE wattage of your panel array over the course of the day and that depends on the season, where you live, and how you have the panels positioned. However, you could certainly take panels configured to provide 500W average charging power over 8 hours to give you 4000Wh of input (granted this won't be 100% efficient but 80% is reasonable.
In any case it's plausible and not nuts to have this get you through several days of power outage and the ability to roughly recharge in a day if one was so inclined to buy half a dozen 100W (average) panels.
Remember this would buffer intermittent loads such as microwave, refrigerator etc.
It's certainly not going to cool your house in the summer, but it would allow you to get through several days of living, eating, entertaining, cooking, and not spoiling your food.
