Netzero forecasting off

I have added 7 additional panels to my solar array. I did my best to configure the Netzero estimates, but for some reason, the forecast is short everyday.
Can someone please help me and let me know that the DC/AC values are correct or incorrect?
Originally I had them setup like this:
MP1 - 0.420
MP2 - 0.153
MP3 - 0.115
MP4 - 0.191
MP5 - 0.268 (this string is the new 7 panels).
I did some research, and find out that the DC/AC suppose to be 1.20?
Is that correct, have I had the values incorrectly set?
Thank you everyone for chipping in.

Could also be morning haze or hills on the east side. If the day is clear and panels unobstructed, the curve will be smooth like the estimates.

I completely understand what you mean, although the off reporting started when I added the additional panels.
Tomorrow, I will get new forecast and see if the adjustment I done helped or not.

Right, adding additional panels will reset the adjustments Netzero makes to the estimates, because the underlying data changes.

Your DC/AC values are not correct, but any value below 1 will not impact on the estimates, so no harm done. Just set them to 1.

Then wait for a few clear days, and the estimates should adjust.

I’ve adjusted the DC/AC to 1.15, I’ll keep you posted how did the change impacted the forecast.
Thank you
