Hope this helps. you really need to be looking through a piece of the yellowed plastic, the way the panels are
The quick answer is the material had either no UV Ultra Violet Light stabilizer or very little. Most plastic materials are not UV stable to start with, other than Acrylic which is invisible to UV. All other materials need a little something to give it the protection it may need from the sun.
The panels are treated with a factory applied condensation control which causes water to spread into a thin sheet, eliminating condensation drop formation and retaining a high level of transparency. 92% light transmission. Lightweight and rigid with excellent impact resistance. Superior clarity, versatility, and weather resistance.
In high UV areas in the US, use 6 mil 4 year clear. Our 4 year Greenhouse Film is extraordinary. It is the best for performance and durability under a variety of severe environmental conditions.

The ability of a plastic to resist color fading is based upon a number of factors including the UV stability of the base polymer and the UV stability of the pigment. These vary considerably from material to material. Additionally, some plastics contain UV absorbers and/or UV resistant cap layers to enhance their weatherability.
Installing Translucent Plastic Corrugated Roof Panels Courtesy the Kemlite Company. Polycarbonate panels contain a translucent UV resistant film on only one side of each panel. Each polycarbonate panel is imprinted with the following: THIS SIDE OUT. The side of the panel with this information should be installed toward the sun or

Manufacturer-Approved Cleaning Procedures for Multi-Wall Polycarbonate, Acrylic and APET The UV-resistant surface treatment on one side of the polycarbonate sheet significantly improves long-term weatherability. Periodic cleaning using proper procedures and compatible cleaners is recommended to prolong the service life. For general cleaning, it is recommended that the following instructions and
Polycarbonate inherently blocks UV radiation by absorbing it and not allowing it to pass through the panel. However, UV also degrades polycarbonate over time. Therefore, Palram adds additional UV protection specifically to protect the sheet, not to block additional UV from getting through the sheet.
