Abstract. Beam-down solar concentrators with a secondary reflector are receiving a lot of attention at present. Large telescopic dual-receiver solar concentrators with Gregorian and Cassegrain alignments have been modelled and investigated in the present study with each telescopic design having a unique set of receivers that are mounted and anchored to the ground. A comparative assessment of both of the telescopic alignments have been carried out along with minimum image radii The results reveal that both telescopic designs are capable of splitting incoming sunlight and facilitating the use of two receivers. For the design and simulation of telescopic designs, Tonatiuh and Soltrace have been employed for a comparative evaluation. Both of the conventional and telescopic designs using Soltrace and Cassegrain, as well as conventional designs by Tonatiuh, produced identical results in the simulation of total power on the receiver, However, a sizable peak flux discrepancy was seen between the results from Tonatiuh and Soltrace.
