Global solar radiation and air temperature were calculated for midday on June 21st. The constructed model was utilized to simulate conditions using meteorological data from a specific summer day in Khenchela under realistic local climatic and operating conditions throughout summer while the physical proportions of Spain's Manzanares plant were reduced to one-tenth scale to project the facility's potential electricity yield. The effect of guides surrounding the collector on the electricity generated was simulated to determine the most effective SCPP for fulfilling the electricity demands of the agricultural area in Khenchela. The simulations revealed that an optimal configuration of nine guides could produce 72 W of electrical power. Results indicated that the efficiency of an SCPP is largely determined by its design dimensions, the surrounding air temperature, and the level of solar radiation. https://jser.ut.ac.ir/article_108057_1e1b8e0be60f755e3649520dbb73df3f.pdf
