If you want to learn you could check out the nerd miner project. Not gonna stack sats but its a cool little project.
You could grab a used S9 and run it using your excess power. They are very affordable and easy to work on. Check out Kaboomracks
Also the Home Mining Wizards telegram is great.
Id second the used s9 option. Follow the s9 space heater guide from cryptocloaks.com, and now you are mining from home with excess energy and heating your home with heat produced by miner. 🤯

Yes, the heater option is great. You can underclock and replace the fans to reduce noise.
