This solar calibration error (also known as the daytime dip) in some solar sensors, can cause solar production to read off by up to 3% and can affect consumption readings to a similar degree as well. Our engineering team is working to resolve this issue and should have it addressed in the next few days. This issue has been discussed previously in the thread: Solar customers: Recognizing the "Daytime dip" and how it might impact your Sense numbers.
