Home electricity bills are skyrocketing. For data centers, not so much.

You can plug anything back into your how power system so long as the reverse current is not more than the ratings of the wires & equipment that current runs through.
In the US, most residential outlets are rated for 15-20 Amps at 120 Volts. You'd need to find a solar panel that matches these ratings. There are what's called "AC solar panels" or just panels with micro inverters that transform the DC electricity from the panel to AC right on the panel itself. As long as the circuit you plug into is rated for it, you can plug as many panels like this into your home power system.
I'd have to check the National Electrical Code (NEC), but I believe that if you're planning on making those solar panels permanent, and since the hypothetical ones in this conversation have "plug and cord" connections, you'd need to hardwire those panels with wiring hidden behind drywall. If you truly plan to use those panels temporarily, such as seasonally, maybe you can make the argument that you don't need to do that.
It's all up to your Authority Having Jurisdiction (AHJ), which is usually your town's or city's Building or Electrical Department.
