it’s weird, but legal for some reason. Giving back energy to the grid can cost money. Shy of just stacking a bunch of batteries, what could I do with the spare summer sunlight?

  • Indoor vertical gardens (LEDs), heat storage (insulated water tank) and any other method of storing energy you’d like to explore (batteries can be myriad of systems/devices - exploring these are good investment for your mind and maybe (if successful) for your home)

    BTW, where are you that it’s OK to charge you? In my state (US), it becomes refund for any energy to you DO use from the grid

    • Usually it’s in places where it’s so unusual to feed back power to the grid that the grid isn’t adjusted to it, or the local regulations aren’t updated for it, so you either have to make sure you don’t feed back power or you need a completely different electricity contract with higher connection fees so household solar can’t pay back enough to cover the fees. It used to be a problem in parts of Sweden a decade ago, but now it’s mostly fixed here.

  • Running an aircon or refrigerator would be the obvious choices, but you could for example also connect an small electrical oven and dry some fruits or mushrooms in it… or get all fancy and bake your own bread.

  • My sister overcools her house so she doesn’t have to run the AC at night (but she lives somewhere hot enough for that to matter - I can just open windows most nights).

    I charge my electric car on it (which I guess is stacking a bunch of batteries). I’ll also cook during that time to use the energy on that.
