Not even maybe. You can get a Powerwall and 6kW of solar for less than $30,000. I would estimate from that drawing the size might be 1.5 kW at the most.2) Cost: Maybe it's still cheaper for on-roof solar panels to generate electricity for the whole house including car charging
Do I understand correctly you are talking about 1.9kW of solar panels? (6x275=1950) How many kWhrs of energy do you expect to generate in a year at your latitude?The solar panel on the roof will have the size of 6 x IBC Poly 275 CS5
My thought as well. This site contains some relevant info Solar Energy Potential at northern latitudes | Off Grid Explorer to which needs to be added the substantial reduction in output due to the panels being nearly horizontal. However, the car port concept would make sense in the tropics where the sun is almost overhead.Do I understand correctly you are talking about 1.9kW of solar panels?

The regulations in California are quite extensive. We have earthquakes so the seismic engineering alone would be costly, not to mention the cost of the structural footings. That is why roof mounted solar is less expensive in California.don´t know much of the regulations in California
In Norway you could set up a building < 50 sqm on your property without applying permission. You only needs to inform.
In another thread I posted the following math. One square foot of solar panel in direct sunlight will produce 20 Watts. Therefore to produce 100 kiloWatts it woul take 5000 sq ft of solar panels or an array measuring 50 by 100 feet. In metric that is about 8 meters by 34 meters.The idea looks neat but I think this is more how future superchargers should be... covered with a large solar roof...
I bumped this old thread of mine. Just saw Electrify America to deploy 30 off-grid, solar EV chargers in rural California.I would like to see Tesla offer a carport with integrated solar roof, Powerwall and charger, all- in-one. What do you think?
I have made a drawing to illustrate my thoughts.

Why are you talking about 100kW? I have a 5.4kW PV array consisting of 16 SunPower panels totaling 290 square feet. That is enough to power my house and charge my MS (In SoCal, so Much lower latitude than Norway) with several thousand kWh sold back to the PoCo at year's end. OP's carport could probably support as many as 12 panels for a 3.6kW array.In another thread I posted the following math. One square foot of solar panel in direct sunlight will produce 20 Watts.

That quote was in 2018, and at that point in the thread, the discussion was about Superchargers. My home system is similar to yours and charges my MX and M3 but I have positive Net kWh consumption and Negative dollar balance at True Up.Why are you talking about 100kW?
