I was never able to find a direct comparison between Photosync Spectra IRD and 3M Crystalline so I decided to run the test myself. I'm using a solar power meter that measures irradiance
67 degree partly cloudy day, Southern California
No glass: 1151 W/m2
Closing notes: Although the Model X may have altered the results because it comes with UV/IR glass all around, it still seems like the premium paid for Photosync IRD is a waste of money. For sure their 80% TSER is untrue.
Surprising findings:
-Tesla OEM S/X rear side window glass outperforms Model Y 20% factory tint + photosync IRD 55%
-Model Y roof lets in less solar irradiance than the X roof
Would love to test a Y or X that hasn't been tinted or one with other tints - this is definitely not an apples to apples comparison as the X comes with different glass than the Y
