The purpose of this study was to evaluate the overall effectiveness of a small-scale, low cost, versatile solar concentrator suitable for the needs of single individuals. The system consisted of a spot-type fresnel lens, and a solar absorber sized for moderate temperature range (80–250 °C) applications. Simple and inexpensive materials were chosen for the construction of the tracking system, frame, and absorbers. The thermodynamic properties of the system were determined from theoretical and experimental estimates of temperature and pressure. Efficiencies as high as 50 % were estimated form irradiance and heat losses measurements. The study proved the feasibility and cost effectiveness of the small-scale solar concentrator prototype for varied applications such as boiling water, solar cooking, and autoclaves.
