Ideas for leftover solar energy

Suppose you have rooftop solar panels, but without storage batteries. That way you are supposed to just use the energy in the moment it's produced, or it gets sent back to the grid.
Basically I don't want to send anything back to the grid because frick grid operators. I can already monitor the solar production and the current house electricity usage, so I know when I am "wasting" solar energy. When that happens I can setup an automation that trigger a relay to turn on something that uses that energy (which ideally also saves/generates money)
So anons have ideas about what the load can be?

>turn on the hot water tank
I already have a solar tank
>bitcoin miner
Initial cost is too high
>Charge stuff
But what. I don't have an EV

    Without batteries, you're getting less power during cloudy days and none at night. Why not just buy batteries to cover those times like everyone else?

      Because in my country having batteries implies installing a proper solar system, which means hiring a surveyor to come up with a project and communicate it to the registry and more bureoucracy and then hire a certified installation company which means 15k+ euro
      However there's a "plugin solar system" clause for which you can just buy 2x 400w panels, an inverter, and plug them in your outlet yourself. Total cost 500 euro max. It's nice to offset consumptions of fridge/pcs/hvac during the day

    Have a pond nearby? Or get yourself the cheapest possible big above ground pool. Build a water tower and pump water up there when you have excess solar, and then dump the water back out over an old-timey water wheel to run a textile mill!

      dishwasher
      drier
      washing machine
      AC (aka air-to-air heat pump)
      being able to turn it all on remotely, when you have excess, is the only good use case for "smart" appliances

      that's more expensive than a battery

    Sure.

    I also thought about a gravity battery using water but alas no pond nearby.

    Uh that's cool. I don't think they are sold for home use yet thoughever

    You can turn them on automatically but you have to load them before use. None of my appliances are smart but I am working on getting a notification on my phone when there is surplus energy so I can start them manually

      It's clear that OP doesn't want to get the proper permits, so selling back to grid is out, but he should just suck it up and get batteries either way.

        I mean op could get 4 old car batteries and put them in the closet. Seriously how tf is the government going to know or care. Imagine believing they'd ignore the fricking roof full of solar panels but somehow magically know OP added a battery.

    I've been wondering the same thing. In my country, the government is partly subsidizing the installation of solar panels, that are connected to the grid. If it's too sunny in your neighbourhood, the network gets overloaded by you and your neighour's solar panels so you get disconnected from the grid. Then you start paying again for your power while your panels are at full production.
    I've thought about it and the solution is a neighbourhood mining rig. You won't make lots of money but at least your power doesn't go to waste

    Use it to run a high powered light, then beam that back toward the sun. Just return the energy that you're not using so you can use it again tomorrow when you need it.

    The correct answer is to install solar panels and also bypass your meter, so you can explain to the power company why your usage is so low

    You could run the fridge temperature a bit further down, closer to zero, and the freezer to as cold as possible.

    >I already have a solar tank
    You might want to heat that to 95°C to elimnate bacteria, especially legionella.

    Im off grid. The answer is basically whatever you can find to put it into battery-wise, phones, batts for tools, charge up extra auto batts-

    Then i put it all into heating or cooling/dehumidifying in summer.
    I use a lava lamp and an ice maker as "heaters". I got the ice maker for free.

    Other than that, appreciate being in a place of abundance

    Use solar power to boil water to power a steam engine to provide power, then use that power to for a spotlight to power your solar panels.
