Abstract: One of the main challenges facing the commercialization of parabolic solar systems is their high initial cost, which is not competitive with the low cost, ease of operation, and reliability of photovoltaic technology. However, one potential solution to maximize their energy producibility and improve their economic profitability is to hybridize the power conversion unit. By enabling reliable power generation and reducing reliance on the availability of solar thermal energy, hybridization can be a valid solution to improve the efficiency and practicality of parabolic dish solar systems. This study aims to assess the energy performance of two hybrid parabolic dish systems: the dish-Stirling system located at the University of Palermo, and the dish-Micro Gas Turbine system located at ENEA Casaccia. Different scenarios were examined by varying the installation site and operational strategy, as well as exploring hybridization solutions of the solar source with conventional fossil fuel or renewable ones. The findings suggest that hybridizing parabolic dish systems with conventional fuels or renewable energies greatly enhances their performance, increasing operational hours and maximizing energy producibility.
