Varying goals for solar

[kevin1]

Daily solar goals are probably better defined by a simple periodic algorithm than by delving into ML unless the ML can predict cloudy weather. I did a fitting of daily solar production and it is fairly predictable, except for those darn clouds.

Solar Production Analysis over 6 years

I’m celebrating the start of the 7th year of solar production on my SolarCity solar system this year and decided to see if I could sort out some kind of predictive calculation that was a function of yearly periodicity, days in service (dirt and degradation), plus any other time factors (like day in year). Now, my solar install preceded Sense, so all this daily production data comes from web access to data coming from my inverter over the years. First I looked via linear regression, at all the …
