The issue is not in the car but in hours of sunlight vs battery SOC when the Sun start giving enough energy to charge... If you charge at 3kW it's a slow charge. In winter it means you end up in the "evening" after all "Sun day" at 3kW and still the battery hardly have more than 80%.

IF you charge at let's say 7-10kW than things change...
