Solar energy reaches the cabin as visible light, ultraviolet and infrared, and infrared is the invisible part that does much of the heating you feel. Kepler's nano-ceramic construction is designed to address infrared heat and glare while filtering UV, which is why a lighter shade can still be a serious heat-focused choice. How much difference you notice depends on the film, the shade and the glazing on your particular Tesla, so ask your installer to compare the exact options for your model rather than relying on shade alone.
