Wow, that would take care of our usual home office base load (Germany, not using electricity for heating)

  It's a siren call for us techies, but reality is less pretty than our fantasies of "cheap base load". I got an offer for a "essentially free" residential turbine including the pylon (8 to 10 meters, the legal limit for a "Kleinwindanlage") in SW Germany - just had to dismantle it and put it on my lawn. And of course pour a huge foundation [2x2m?] and have an accredited electrician do the necessary alterations. Nope. It didn't even produce enough electricity to offset the maintenance costs - no idea how I should offset the costs for moving it, even with the free capex. And I did the math about 3 years ago: Prices for both PV and batteries dropped a lot since then. For late fall/early spring I would be better off by adding a PV carport (2 cars). I could also finally automate charging my batteries while electricity is cheap during Dec/Jan, might even be worth bumping my existing battery from 28 kWh to 42 kWh. To be fair: The math might work out in the Northern Germany; but I would not bet on it.
