It would be fun to see this with local daylight hours mapped to the squares, so I could get a feel for where my consumption is at within "daylight" vs the whole "day"

SunCalc is a good tool for this, if you're interested: https://github.com/mourner/suncalc

(I've used it on a personal project, and the API was a little awkward but the results are good: https://daylight.website/)
