Solar energy reaches your Tesla as visible light, ultraviolet and infrared, and infrared is the invisible part most people associate with a hot cabin. Kepler's nano-ceramic films are designed to address solar heat without depending on a dark shade, which is why a lighter Kepler film can still be a serious option for heat comfort. Visible light transmission and solar heat performance are measured separately, so compare the exact film and shade rather than assuming darker means cooler. Your installer can show you the published figures and advise on what suits the glazing in your vehicle.
Ask a local tinter whether they carry Kepler film or can get it. For more information, see quick quote.
