It won't come as a surprise to read that April 2025 was a sunny month. We've all seen how sunny and warm it's been for almost the entire month. With an average of 250 hours of sunshine, according to Dutch meteorolgical society KNMI, it was one of the sunniest Aprils in history, even though it was even sunnier back in 2020.

Besides sunny, it was also quite warm, and there was once again little rain. In the east it rained more than in the west, but by now it's starting to become quite dry in the whole of the Netherlands. A few heavy showers to wash the dust off the solar panels would be more than welcome.

Rates on the dynamic market below zero

For the first time this year, electricity rates on the dynamic market briefly dipped below zero: it happened on April 27, 2025, not coincidentally on a sunny Sunday. For those with dynamic rates, it was an opportunity to try to temporarily switch off their inverter, in order to save money. You can read how to do that here.

SMA will also introduce a possibility this year to link the Sunny Home Manager to the dynamic tariffs, which should make it unnecessary to manually switch off inverters. Incidentally, the consistently sunny weather resulted in little 'imbalance' and therefore once again disappointing results for those who trade on the imbalance market.

In the coming period it will be a bit cooler and there is a bit more chance of a rain or thunderstorm. The ground needs it, and the solar panels need it too. With twice as much sun in the past months as in the same period last year, we've been able to benefit greatly so far; now let's wait and see what the summer will bring!
