A mid-year to mid-year solar blog is proving a bit of a pain presentation-wise - so we've decided to move to an end of year review instead. We also added a Modbus energy meter to our solar installation in November, which will give us accurate production, export and self-consumption stats from now on - so next year we will have a full year dataset of much more detailed (and hopefully interesting) statistics.
For now, here are the 2020 (January to December) highlights / lowlights for Solar Production. As can be seen December's really poor weather has resulted in many of the bottom production figures, and May continues to dominate the top 10 list.
| Date | Bottom 10 Production |
Date | Top 10 Production |
|---|---|---|---|
| 18/12/2020 | 186 | 14/05/2020 | 26,133 |
| 30/11/2020 | 334 | 1/06/2020 | 25,268 |
| 11/01/2020 | 339 | 05/05/2020 | 25,254 |
| 07/01/2020 | 379 | 11/07/2020 | 25,129 |
| 03/12/2020 | 442 | 20/07/2020 | 25,125 |
| 21/12/2020 | 447 | 31/05/2020 | 24,931 |
| 20/11/2020 | 464 | 25/05/2020 | 24,881 |
| 13/12/2020 | 467 | 30/05/2020 | 24,835 |
| 28/02/2020 | 473 | 20/05/2020 | 24,701 |
| 16/12/2020 | 533 | 29/05/2020 | 24,675 |
This graph (pre-Modbus installation), contrasts Production with 'Deemed' Export - fixed at 50% 'of the production figure.
Finally we can see the impact of working from home during the pandemic on our electricity consumption - a comparison with 2019 shows a notable increase in electricity use. We're not entirely sure why there is such a leap in July 2020, but it is probably due to a combination of factors: family visitors, the end of that incredible spell of sunny weather, and Martin being issued with a work laptop.
See you in a year!
