detecting the eclipse

Although we couldn’t see the eclipse, our solar PV system detected it.

Here is the solar PV data from dawn up to 11 am, plotting production against time.  The orange background is what we would expect with a clear sky (no cloud) and full sun (no moon) at this time of year.  The black line shows the production today.  It is way down on average, due to the clouds.  But that dip: that’s the eclipse!

And the weather now?

11:20, full sun
