    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.

      55 degrees North? Damn, we’re in Seattle and we’re at 47.6 so that’s some seriously lacking sun compared to the rest of the US. That’s incredible news.

        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.
