Two of Europe's best-selling EV SUVs, sized for solar
The Model Y Long Range and the ID.4 Pro are both mid-size electric SUVs with similar-sized batteries — 75 kWh vs 77 kWh — but the Model Y's 14.9 kWh/100km consumption beats the ID.4's 16.8 kWh/100km by a meaningful margin. That gap compounds over a year of driving into a real difference in solar panel count and annual savings.

Common Questions
The ID.4 uses about 13% more energy per 100km than the Model Y, so for the same annual mileage it typically needs a slightly larger solar system to cover the same share of charging. VoltSun calculates the exact panel count for your address below.
With a similar battery size but lower consumption, the Model Y generally gets more driving range out of the same solar system than the ID.4 — translating into faster payback, all else being equal.
The Model Y Long Range is rated at 14.9 kWh/100km versus the ID.4 Pro's 16.8 kWh/100km — roughly a 13% efficiency advantage for the Model Y in this comparison.
Both charge fine from a home solar setup with a standard AC wallbox — the difference isn't charging speed, it's how much energy each car needs per km driven, which is what determines how many panels you need and how much you save.
