That shows very well how variable the weather can be, from day to day, and from hour to hour.
Each day’s generation can be integrated, to show total power per day.
|Daily power generation, in kWh (grey bars), along with a running average (lower quartile, median, upper quartile, maximum; orange areas), over the previous 7 day sliding window.|
And that also shows how variable the weather can be from day to day, and how January got steadily gloomier. But even a median generation of 10kWh/day is better than a poke in the eye with a burnt stick.
Rather than continually blog about all this, I’ve set up a page on my other website, which will keep the up-to-date charts.
