Describe the issue you are experiencing

When comparing last year to the current year in my energy dashboard it looks like this:

I have two solar sources configured. The second one is behaving in a strange way in graph for last year. (It did not exist before august, so that is correct)

Describe the behavior you expected

I expect the two bars to correctly stack on top of each other.

Steps to reproduce the issue

Comparing last year to the current year in the energy dashboard with multiple solar sources.

Can you export a CSV of the period with the bug pls? It's hard to reproduce this

Oh, i forgot about that.

It's hard to reproduce for me as well. As it doesn't always happen it seems. playing around sometimes messes it up.

More detailed graph with the error:

Happens at the per device graph too:

Out of curiousity I setup a similar dataset but couldn't reproduce anything like the OP showed (at least not on dev)

It doesn't always happen. It is inconsistent and happens after playing around with the range and compare options a bit. Had it happen on Windows/Chrome and in the ipad app.

If you can figure out what the exact steps "playing around" entails that would help. I also "played around" (enable/disable compare, changing windows), but didn't get it.
