This study focuses on optimizing a fixed-focus Scheffler dish solar concentrator with a dual-axis tracking system, specifically designed for the northwestern region of Mexico. The objective is to improve the performance of the system and operating hours by using an opto-geometric analysis and a mathematical model that links key design parameters, such as the interception angle and dish diameter, to the overall efficiency of the system. Through simulations and empirical evaluations, the impact of the solar declination angle and hour angle on solar tracking and concentration was analyzed. The dual-axis tracking system implemented allows precise adjustment to the seasonal sun and daily variations, thereby maximizing energy capture throughout the year. The results indicate that, in the Mexicali region, a system with a 60° interception angle achieves the best annual performance, capturing up to 1008.4 kWh and operating for over 3300 h per year. The conclusions highlight the importance of an optimized design that balances cosine losses and operating hours, maximizing system efficiency in a region with high solar irradiance, and emphasizing its potential application in the local industry and thermal energy generation.
