Selecting Surface Inclination for Maximum Solar Power

Maximum efficiency of surfaces that exploit solar energy, including Photovoltaic Panels and Thermal collectors, is achieved by installing them in a certain inclination (tilt). Most common approach to select an angle equal the location’s latitude. This based on astronomical calculations sun’s position throughout year but ignores meteorological factors. Cloud coverage aerosols tend change direct irradiance also radiance sky distribution, thus horizontal receive larger amounts than tilted ones specific atmospheric conditions (e.g., cases cloud presence). In present study we used 15 years data, from 25 cities Europe North Africa order estimate optimal tilt related energy benefits real conditions. Data were retrieved Copernicus Atmospheric Monitoring Service (CAMS). Four diffuse irradiance, various models are compared, their differences evaluated. Equations, extracted properties regressions, suggested regions, where no climatological data available. addition, impact parameterized using Modification Factor (CMF) equation proposed angle. A realistic representation photovoltaic production subsequent financial analysis additionally performed. The results able support prognosis outcome should be part planning decision making for optimum power exploitation into international clean transitions. Finally, compared global at Northern presented.
