The heat you feel through glass arrives as part of the solar spectrum: visible light, ultraviolet and infrared, with infrared making up a large share of the warmth you notice even though you cannot see it. Kepler's nano-ceramic films are built to act across that spectrum rather than simply darkening the glass, which is why shade and heat performance are separate questions. In practice it means a cooler cabin after the car has been parked in the sun, less glare while driving and less UV reaching the interior surfaces. Compare the exact film and shade you are considering, and ask your installer which combination suits the glazing on your Tesla.
