    I am curious, what is the rating for the install? And roughly what longitude is that? I’d love to get some for my home though a few years away to save up for it

      10 kWp but ~45% of it on the northside. We’re in south Germany, 49ish degrees north. We redid the roof (bought a house with resistive heating and almost no roof insulation… Picked up a bit of a project here) and covering 60% of the south side with panels is required by law (at least to get some subsidy), but we would have done anyway. Don’t use this day do evaluate the project :)

        Thanks for sharing, that’s actually really cool to find out real life values. Out of interest what sort of per day values you get in different seasons?

            Looking forward to seeing it, I’d love to get solar and to ditch gas for a heat pump, but funds are not there 😔

            one day… one day…

              A heat pump is also in my future, but the funds need to recover from this round of energy efficiency interventions first.

              But even before then, having resistive heating might not be the best (or the cheapest) but I love to be able to measure all my house energy needs in kWh without conversions (sure if you have gas you can count cubic meters, but it’s a lot of approximations).

      I took the screenshot then and I was too lazy to do it again before posting :) Also, sometimes the integration that does the prediction becomes more realistic and the difference would have been less strong. But it looks like it didn’t re-evaluate the prediction, and the second half of the day was even worse :)

      You are correct of course, generation happens without direct sunlight. In fact, today it was raining and I never saw the sun (until literally 5 minutes before sunset, go figure). It’s actually awesome to get what I get on a rainy day, jokes aside.

      I can confidently say that there was no direct sunlight involved today because I have panels on the northwest side, that doesn’t get any direct sunlight these days, and they behaved just like the south. Even pale sun makes the south take off way past whatever the north string can do. Didn’t happen today
