The commercially available PTC comes with 80 degree rim angle. what type of manufacturing advantage made the manufactures to restrict the PTC with such rim angle.
It is restricted because of the manufacturing process. If you go for a lower rim angle it is harder to make the shape - presumably they press it from flat sheet. That is why you can make cylindrical concentrators with almost any rim angle, but parabolic ones are harder.
Not always. They may have those ones have special uses. The optimum angle theoretically should be 45 minus the half-subtended solar angle at the eye on the earth (0.267). But anyway, it depends on the collector manufacturing (roughness, reflectivity, etc.).

can you help me with an optimization of the rim angle for a ptc working with errors
how we can consider that the perfect rim angle is 110° any reference plz
thank you very much
