My decarbonized life: this is what self-sufficiency is all about
When my wife and I decided to disconnect from the gas supply, purchase an EV, put an inverter and 17 solar panels on the roof, install a heat pump and two modules in a Huawei Luna battery, we knew were making an investment that would pay off.
For the last couple of years, between late April, early May and mid-late October, solar power covers our entire household needs (the occasional peaks are minimal, hardly significant, and may be due to the heat pump heating water and a kettle at the same time).t also allows us to fully charge the car battery (which we generally keep at around 70%, more than enough for daily use that rarely takes us below 50%, except on long journeys), and best of all, the car battery charges overnight.
The screenshot shows Friday’s curve: the day before I went to Segovia form my home in Madrid to teach a class, so I had to charge the car a bit more than usual. Still, since the house battery was already full relatively early, we were able to charge the car to 80%, and wake up this morning (the three graphs below) with our homework already done, again covering all our needs, after which we were pouring electricity into the grid. This is what self-sufficiency is all about, and it’s pretty cool.
