Solar: Two Years On

Two years on we are still generating solar power, and the 'trees planted' are mounting up (although they appear to have changed the method of calculation at some point during the year so the numbers here have leapt up!):

Our best performing day for solar generation was 14th May 2020 when we generated 26.13 Kilowatt Hours (kW-h), with the month of May remaining the highest month for overall solar generation. Below are the Top 10 and Bottom 10 dates for solar generation throughout the year.  May dominates the top 10, and as last year most of the bottom 10 dates are near the shortest day of the year.

Date	Watt Hours		Date	Watt Hours
14/05/2020	26,133		12/12/2019	263
01/06/2020	25,268		12/11/2019	338
05/05/2020	25,254		11/01/2020	339
11/07/2020	25,129		18/12/2019	357
20/07/2020	25,125		07/01/2019	379
31/05/2020	24,931		26/12/2019	426
25/05/2020	24,881		28/02/2020	473
30/05/2020	24,835		13/12/2019	479
20/05/2020	24,701		02/01/2020	549
29/05/2020	24,675		14/01/2020	617

This is how the years compare.   In the summer months, the trimming of the Yew Tree may have helped to boost solar generation earlier in the day, but it isn't really possible to make direct comparisons from one year to the next as generation is of course hugely dependent on the weather.
