Tesla Powerwall 2 and Solar PV in the UK [74]: November 2025

A narration-free report on our property's electrical system, which includes two solar arrays and three Tesla Powerwall2s with Backup Gateway, for the month of November 2025. The 3.92 kWp SW array was installed in October 2011 on the roof of the house which has a pitch of about 30° to the horizontal and azimuth 227° M. The 3.05 kWp SE array was installed in January 2020 on the roof of the garage which has a pitch of about 60 degrees to the horizontal and azimuth 137° M. The first Tesla Powerwall, which has a nominal storage capacity of 13.5kWh and maximum continuous discharge rate of 5kW, and Gateway 2 were also installed in January 2020 in the garage. The second Tesla Powerwall2 was added in November 2023. A third Tesla Powerwall2 was added in November 2024. Tesla had announced that it would soon stop shipping Powerwall2s, and the Powerwall3 is incompatible with the Powerwall2s, so it was "now or never". At the same time, the zappi was moved from L1 to L3 and the Annexe's storage heaters were moved from L1 to L2. The property is served by a three phase grid supply, rated at 100A on each phase, via a smart meter which replaced the old meter on 8th February 2024. We are currently on the EDF GoElectric Overnight tariff for EV owners, which has a low rate from midnight to 5am all year round. A single phase zappi car charger was installed in the garage in April 2021 and a fully electric (BEV) car arrived, two months later than expected, on the 28th of May 2021. The property consists of a 5 bed (currently 4 bed + study) detached house and an annexe (a Studio flat above the garage) and the figures shown cover the electrical activity in both residences. The usage is high in the winter due to the annexe being heated by two electric storage heaters, and this cost is covered by the rent paid by the tenant but is included in the figures in the video as it is not possible to exactly separate the electrical usage of the two residences. The main house is still centrally heated by an oil boiler but the third Powerwall is part of the preparation for an electric heating system of some sort at some time in the future.
