    Those potentially have the same issue. The solution to filling the gaps in production from renewable sources is not necessarily more panels or more windmills, it’s having energy storage somewhere to keep surplus energy when it’s being produced (e.g. during the day, or when the wind is blowing) available to be used when it’s not.

    So in your example, each home could also have its own battery bank. Or, a larger battery bank could be placed somewhere on the electricity grid.

        If your appliances are efficient and your usage is moderate, you don’t need much to generate enough power to run your home. And, provided you don’t also need to charge an EV in the garage…

        The 8 Bit Guy just did a video detailing his setup, which is all solar panel driven, and he rode out a day in the recent Texas heat running his air conditioners and so forth just on his solar panels and stored backup power. He has a comparatively rinky-dink number of panels, just a few over his little side porch and a couple more hung on his fence.

        I imagine someone with one side of their roof paneled plus or minus a small windmill could easily power their own home as well as provide a surplus to charge a battery bank.

          Just to add to this, we had 14 panels installed with a powerwall on an East/slightly NE, West/slightly SW roof at 55°Northern latitude. In the 7 weeks since we had them installed, every day we’ve made more than enough power for our usage. On more than 60% of the days so far we’ve filled the battery too and had to put up to 7kwh into my car. The worst days we’ve still made enough to power our house for more than 24 hours. This is genuinely way more than I ever expected to make and if we get a fraction of that through winter we’ll not need to charge the battery from off peak electricity as much as I had planned.

          Now, granted this far north we’ll cycle from one extreme to the other but it seems like such a simple win to have panels for when you can and storage to smooth out usage on everything we can. You can get a surprising amount of power from just a “bright” day, even with cloud cover.

              I was and still am blown away. I’m already thinking how I can fit more on to our house and for other efficiencoes we can make, next one is likely to be a heatpump.

              Our system has 5.6kwh theoretical capacity but were split 10 panels to the rear and 4 to the front. Even still, we’ve manage to peak at 3.64kwh output. For context we’ve had our system just short of 8 weeks and made 821kwh as of this post.
