Theoretical Study of The Use of Lfscs in Terms of Energy for Textile Factories: The Example of Saint Louis in Senegal

Abstract

Senegal has a high potential for solar energy but mainly depends on fossil energy resources. Industries, particularly the textile sector, could benefit from the use of alternative energy sources to reduce costs and improve the environmental footprint. This study focuses on the use of linear Fresnel solar collectors (LFSC) coupled with an Organic Rankine Cycle (ORC) system to produce energy in textile mills, particularly in Saint Louis. The objective was to size a Fresnel solar array and evaluate its energy production for two different periods: the sunniest month (April) and the least sunny month (August). The findings demonstrate the substantial solar potential of the region, with significant sunshine throughout the year. The maximum direct solar radiation recorded on August 15 and April 25 was 898 W/m2 and 945 W/m2, respectively, at noon. The maximum energy production for one row in August is 24.4 kWh, and in April, it reaches 25.7 kWh. It is noted that, for the use of the Fresnel linear system, the number of rows will depend on the energy needs of the textile factory.
