China's flagship SUV vs the best-seller, sized for solar
Xiaomi's YU7 Max has become one of the most talked-about electric SUVs of the year — a big, long-range flagship aimed directly at the Tesla Model Y. On solar, though, the benchmark still has the efficiency edge: the Model Y Long Range uses 14.9 kWh/100km against the YU7 Max's 16.5 kWh/100km, so the Xiaomi draws about 11% more energy for every 100km driven. Where the YU7 Max pulls ahead is capacity — its 102 kWh battery and 675km range far outstrip the Model Y's 75 kWh and 533km — but for solar sizing it's consumption, not battery size, that sets how many panels you need.
YU7 Max and Model Y are evenly matched here — check the metrics below for the trade-off that matters most to you.

Common Questions
For the same annual mileage the Model Y's lower consumption (14.9 vs the YU7 Max's 16.5 kWh/100km) means it typically needs fewer 400W panels than the Xiaomi. VoltSun calculates the exact count for your address and driving habits below.
No — panel count is set by how much energy the car uses per 100km, not by battery size. The YU7 Max's 102 kWh pack is far larger than the Model Y's 75 kWh, but that buys range and charging headroom, not a bigger solar array.
On the figures in our database the Model Y Long Range is more efficient at 14.9 kWh/100km versus the YU7 Max's 16.5 kWh/100km — roughly an 11% advantage that adds up over a year of driving into a meaningfully different solar system size.
Per km, slightly — its higher consumption means a same-size solar system covers a smaller share of its charging. Its far larger battery and longer range cut down charging stops on long trips, but day-to-day solar cost still comes down to consumption, driving distance, and your electricity price.
