What about mining for fun in the summer with an old asic (that doesn't cost much)? Of course it won't mine much. I wonder if it's better than selling the electricity to grid at low (negative?) prices.
But yeah, no AC has to be involved. 🤔

summer in Europe is not the best time for solar. there's more sun, but it's also too hot. best months are may and June.
in summer, you are more likely to also need ac to cool the house, so the consumption will be also much higher, so there'll be less excess.
selling to the grid is usually not a good idea. virtual battery means you don't have to pay for energy you consume later, but you have to pay distribution costs, which are around 40-60% of the price. you can also sell for money, but that involves a lot more territory compliance and income taxes. it's much better to consume what you produce. so batteries are a good idea.
or look at it like this - the cost of electricity is 6-8 cents per kWh when produced by a system without battery, double if you have battery. if you can use it in any other way (even storing in battery), it is a better deal. because the old miner will not produce more that much per kWh, probably less than half.
Mining for fun is always profitable!!
