I noticed in the past month that my daily energy production doubled in size. The problem is persistent but doesn't show up on a daily basis. I don't have a definite fix but can however fix these weird spikes manually.

I decided to post to show how to correct these spikes when they occur.

Let's say there's a weird spike in the evening which adds 100kWh to my Solis Energy Today kWh. This would look like this:

The problem is located on a sensor which reports the daily kWh total. In this case it's Solis.

My next step would be to go to the settings menu and look for Development settings > Statistics Tool and look for the sensor which has the problem.

Then it's a search to the right moment on which the error occurs. In this case see:

Now just adjust the incorrect value to the desired one. In my case this is 0. Then just reload the energy dashboard and the error won't show.

Good luck for whoever gets into the same boat.
