It is almost the end of February 2026, and we’ve already had some wonderfully sunny and warm days. It makes it tempting to think that winter is over. We know better, of course — last year we still had cold days well into May. But from a solar power perspective , we can safely say: winter is behind us. Naturally, the first question is: how did it go? Was there enough energy? That question can be answered in many ways. We knew in advance that we would not have enough energy during winter — and that was by design. To generate sufficient solar power on the shortest day of the year, December 21st, we would need so many panels that for the rest of the year we’d be drowning in excess energy. On top of that, such a system would simply be far too expensive. In winter, we don’t just get less sun — we also need more energy . As temperatures drop, we try to heat the houses as much as possible using electricity. Demand goes up exactly when production goes down. And then there’s the heat pumps...
