According to the Libyan government's newly released strategic plan, renewable and environmentally friendly energy sources would provide 30% of the country's power by 2030. The goal of this research is to shed light on solar energy technologies that may be used to generate clean and sustainable electricity. An energy-economic-environmental study of five Concentration Solar Power (CSP) technologies (parabolic trough, solar dish, linear Fresnel reflector, solar tower, and concentrated PV solar cell) was conducted for 22 selected locations in Libya. The Levelized Cost Of Energy (LCOE) was chosen as a reference for identifying which technology would be most suited for each site. The economic estimates include the cost of environmental damage caused by carbon dioxide gas (CO 2) emissions from fossil-fuel-powered power plants. This technique allows clean and renewable energy to compete fairly in the global energy market, even in countries that produce oil and subsidize electricity.

According to the data, the solar mirror technology in Libya has the lowest LCOE of all the technologies evaluated in this study. The LCOE estimates varied from 0.01 to 0.04 dollars per kWh. The clean energy produced by the solar tower surpassed 100 MW, or about 400.332 GWh. Furthermore, the adoption of clean concentrating solar energy technology avoided the discharge of 4,235 tCO2/year/MWp.

In this study, an examination was conducted on weather data gathered from the Murzuq weather station over a period of nine months, specifically focusing on 15-minute time series solar radiation data. The data was sourced from the Center for Solar Energy Research and Studies in Tajoura-Tripoli, through a collaborative agreement between the Faculty of Engineering at Wadi Alshatti University and the research center. The information collected encompassed various solar radiation components, such as global horizontal solar radiation, direct normal radiation, sky-diffuse solar radiation, and ground reflected solar radiation. The aim of this study is to verify calculated values of these components using mathematical models by comparing them with their measured values. The investigation revealed that the Earth's reflectance value for the region was estimated and determined to be around 0.4. It is important to note that this figure was different from the typically advised value of 0.2 that was given in previous literature. ARTICALE INFO.

The present study presents a regression function for optimum tilt angle for fixed mode flat-plate solar harvesters suitable for different locations in Libya, sky conditions and albedo values. The research based on 14 years -15 minutes time series solar irradiation components which provided by Solargis database platform for 24 different locations in Libya, based on the contract signed between the Solargis Company and Wadi AlShatti University. Several transposition models are applied - corresponding to each location - for estimating the tilted global solar irradiance components according to recommendation of a local recent study. The proposed model corrects the optimum tilt angle by involving the three components of the solar irradiation: direct beam, sky-diffused and ground reflected solar irradiances. The results proved the applicability and reliability of the obtained regression model. In addition, results showed the high potential of the proposed model for use in engineering design, eco-energetic analysis and optimum design processes.
