In this paper will be presented the process of design, construction and optical performance analysis of a low cost solar concentrator for medium thermal applications.. To avoid complexity of design of an specific shaped surface a common offset parabolic antenna is used to make the reflector. This study develops and applies a new mathematical model for estimating the intercept factor of a new solar concentrator based on the geometric and optical behaviour of the concentrator in Cartesian coordinates. The goal of this paper is to present optical design of a low-tech solar concentrator that can be used as a potentially low-cost tool for laboratory-scale research on the medium-temperature thermal processes, hot water systems, heating systems, cooling systems, polygeneration systems etc. The paper also describes the prototype construction process and ray tracing study with a solar concentrating system consist of three offset parabolic dish reflector.
