Mysunpower app generated percentile

[snifferpro]

Not a math person by any means but I’d like to know how the SunPower app
arrives at the Daily%, Monthly%, Yearly%, and Lifetime% figures.
Doing a spreadsheet and would like to generate those figures as I key in datly data.

Thanks.

My PWRView app provides the same breakdown (2024 example provided). The app tells me how many MWh it produced in a given month. I also keep a spreadsheet of the monthly totals so that I can figure out if the POCO is being honest. I take a morning reading off the meter and bang that off what my system says I generated / used. I'm retired. I have nothing else to do with my time...

Is this something you wrote yourself? I'm looking for the formula that SunPower uses to generate
Daily%, Monthly%, Yearly%, and Lifetime% figures in their mySunPower app.

Unfortunately, no. That comes from the GENERAC PWRView app. When we first got our system, that app was not entirely... accurate. They had a desktop web version that provided a lot more detailed statistics. About a year in, they updated the app and shut down the web portal. It's been more spot on - I can go down to my inverter and get the statistics off the access screen from the day, and they match what the app is stating. The app has been further enhanced to give me details on what each PVLink is doing (today, it's OVERCAST and SNOWING, so we have little power to look at...) if I scroll down on that totals windows.
