150 - 300kwh of free electricity per month. Mine crypto?

A family member recently installed a solar power system that turned out to be more efficient than they anticipated. As a result, they are generating an excess of about 150 to 300 kWh of electricity each month more than they actually need for their household consumption. The utility company zeros out their electricity bill, but any surplus energy produced is simply absorbed by the grid without any additional compensation. They said that I could use this extra electricity by setting up a cryptocurrency miner. This way, the excess energy wouldn’t go to waste, so I'm hoping to use it to make some profit. I’m curious to know if there are any small or older models of crypto miners that would be worth plugging in to utilize this surplus electricity. Any recommendations or advice would be greatly appreciated!
