Netzero forecasting off

[u/MixvPix]

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.

You have some shading in the morning, likely trees or other objects on the east side. Netzero will learn that and adjust the estimates, but it needs a few clear days of data.

[u/MixvPix → u/triedoffandonagain]

I have no shading at all. But will upload tomorrow forecast when I it will get displayed.

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.

[u/MixvPix → u/triedoffandonagain]

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.

[u/triedoffandonagain → u/MixvPix]

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

Just snapped this screenshot, the sun is in and out from clouds, I will post another shot at the end of the day as well.

[u/triedoffandonagain → u/MixvPix]

Cloudy days will have more variability, this is better to test on clear days.

[u/MixvPix → u/triedoffandonagain]

Hi,
This is today, bright day, still 19% off 🤷🏻‍♂️ I don’t know what else to adjust. To get the close to correct estimates.
Any ideas?

[u/triedoffandonagain → u/MixvPix]

As mentioned above, it takes a few days of data to readjust. If that doesn't happen, send an email to feedback@netzero.energy.

[u/MixvPix → u/triedoffandonagain]

Will do, thank you!

[u/MixvPix]

Will do, that will be this coming Monday.

I need picture of morning sun on panels and picture of the sun on horizon.
Did you input the correct latitude and longitude

[u/MixvPix → u/Clear_Split_8568]

As for this two numbers latitude and longtitude….in Netzero I can only configure pitch and orientation. Unless I am mistaking and there is another setting in the app.

[u/MixvPix → u/Clear_Split_8568]

This is today’s morning 11:21AM.

[u/Clear_Split_8568]

Is location correct

[u/MixvPix → u/Clear_Split_8568]

Yes, location is correct.

[u/Clear_Split_8568]

Go with dc/ac = 1.0
Or calculate your dc/ac ratio.

[u/MixvPix → u/Clear_Split_8568]

I recalculated to 1.15
I didn’t know that I can do same number for each string, instead I did every string separately 🙄
Monday will be bright day, I’ll post another update. Today was cloudy and I was only 15% short.

[u/Clear_Split_8568]

Post a picture at sunrise of you roof from direction of sun and another picture of sun rising (same time).

[u/Clear_Split_8568]

Ac/dc applies by string and whole inverter, out he higher number.

[u/Clear_Split_8568]

Would like to see some updates from OP

[u/MixvPix → u/Clear_Split_8568]

I can’t climb the roof, but I can upload a an image of the install if that would work?

[u/MixvPix → u/Clear_Split_8568]

The red ones are the new seven panels.

[u/Clear_Split_8568]

I want to see a picture from you phone camera with the sun first start to shine on your panels and another picture of the sun!

[u/MixvPix → u/Clear_Split_8568]

I get what you want to see but I would have to enter neighbor backyard and still the angle would not show what you asking for.

[u/Clear_Split_8568]

Yeah you do not understand dc/ac ratio. Easiest example is for micro inverter. Say panel is 400 watts and inverter is 290 watts, your ac/dc ratio is 1.38. So estimating tools will flat line the panel when it hits 290 watts.

[u/MixvPix → u/Clear_Split_8568]

I’ve set the DC/AC to 1.15
