Scheffler fixed focus concentrators are used for medium temperature applications. These concentrators are lateral sections of paraboloids and provide fixed focus away from the path of incident beam radiations throughout the year. In this paper design of a Scheffler Solar Concentrator system and it’s thermal characterisation is presented. In the second part of the papar thermal characterization of a flat plate collector is presented which was done under identical conditions as the scheffler concentrator. In case of flat plate collector efficiency is high in the low temperature region (500C to 800C) while that of point focus concentrator was found to be low and in subsequent temperature range (800C to 1500C) it increases and remains stable almost throughout the range. By super imposition of two performance curves, system of flat plate with scheffler may give a stable higher efficiency throughout the range of low to medium temperature range (500C to 1500C)
