Ich fahre seit einiger Zeit eine Propaganda-Kampagne gegen die üblichen Fossilköpfe in meinem Stream auf Linkedin.Das geht dann so.
I live in Amsterdam, 52.36N, 4.9E. That is about as far north as Edmonton, Calgary, or Minsk.
I have a house with a roofline that points to 135S, so I can't install south-facing solar. Instead I have 9x 370Wp facing ENE and 16x 370Wp facing WSW, for a total of 9250 Wp. That is not a particularly maxed out installation – the roof could carry more and I should have built larger.
The situation is far from optimal: The ENE-side sees the shadow from a street tree in Winter, and the SWS-side sees a shadow from the house itself for the late hours in summer.
I used to use 5.500 kWh a year for the people and machinery living in the house, and to that we have now added the power to charge the car, about 2250 kWh a year for 15000 km – minus for whatever we collect from fast chargers (which basically only happens on vacation trips).
We (still) have net metering. In October alone, I used a net 36 kWh so far. In September, I fed 139 kWh into the grid.
Our net metering interval goes from July to June, and currently I am at 1100 kWh in my favor for the current interval. Overall, and counting the car, the 2023 interval was still 660 kWh in my favor. The 2022 interval was 2700 kWh in my favor.
I do use about 25% of my self-produced energy directly, currently. That is because we don't have a house battery, yet. Next year that will change, and I expect to greatly increase my direct usage quota.
So yes, we do not pay for electricity, and we drive our car for free, and we still get paid from our electricity provider. If you live south of me, and/or have a proper south facing roof, you could do the same.
Was that expensive?
We paid around 8000 Euro for the solar modules, inverter, installation and paperwork, around 2000 Euro for the charge point and we will pay <8000 Euro for a 20 kWh house battery.
All of this has been basically paying for itself within three years.
