The last month of 2019 was very dull in North East England for the first three weeks, before a sunny period between Christmas and the New Year rounded things off. Overall, the Met Office recorded 60.9 hours of sunshine in the month.
Given the generally murkiness of the winter, the bulk of the savings and benefits this month again come from using the Octopus Go tariff. This supplies heavily discounted (5p/kWh) electricity between 00:30 and 04:30, which we use to pour dirt cheap electrons into the 14 kWh Tesla Powerwall domestic storage battery + 100 kWh Tesla Model X and 30 kWh Nissan Lead + (new this month) 1 kWh Riese & Müller eBike.
In overview, December 2019 produced £502.45 in financial savings and benefits. And 796 kg of CO2 emissions avoided. The detailed monthly performance report can be downloaded by clicking the image at the end of this page.
