141kwh for January
Last year I did 120kwh from 12th to 31st and equates to 6kwh/day and slightly up on the expected target of 5.42kwh/day.
This year with an extra 11 days we managed 141kwh, which worked out to 4kwh/day and well below target of 5.42kwh per day.
Now the first 11 days of Jan are expected to be worse than the last 20 days which skews the above a bit. However, over a like for like 20 day period from the 12th Jan we only did 96kwh which is 24kwh down on last year. If you wan that in a %, that's 20% down.
It really has been a bad month for solar, fortunately it is only January and the second worst month of the year!
