Photovoltaic system: How many kWp are enough for a house?

With a Model X, that could work.

Indeed. I was not even aware that it has a tow hitch and can pull that much...

And to get back on topic: For electric cars, the photovoltaic system can't be big enough. So fill the roof completely!

Well, you could also consider a Tesla M3.

Definitely not

I think Tesla is great, no question. But that's a car for people who have enough money or who really want it.

I need a car that is affordable and meets my criteria. The Tesla is way, way above that.

I can check tomorrow, but I think we're even above that.

Gladly. What will be exciting is the degree of self-sufficiency over an average of 12 months and the self-consumption. My solar installer only connected the energy meter for me 3 days ago, so I can check the consumption live. I myself hadn’t realized that we consume between 12-15 kWh and 25 kWh per day. I find that intense now, without the heating period and with 12-15 kWh per day, if the electric car isn’t being charged. Without photovoltaics and tracking, one isn’t aware of that. Hairdryer on 2 kWh, stove on 2.5 kWh, oven on 4.5 kWh. TV on 150 Wh, hot water 3 kWh, etc.

Therefore, I’m now an even greater advocate for a photovoltaic system. Storage isn’t essential unless you don’t know where else to put the money.

Our 25.6kWp system (East/West) has also been running since yesterday. The first full day is today. Tomorrow I can then show our values.

The trailer discussion is one-dimensional. Many households have two cars. One drives most distances economically with electric power and the other pulls the trailer when needed.

Electric cars are also cheaper in consumption if you don't get the electricity from the roof. With 15 kWh per 100 km at 30 cents per kWh, you barely spend €4.50 and also save on operating materials, wear parts (especially brakes), and inspection costs.
