The objective of this work is to calculate, from formulations, the incidence of solar radiation. Solar energy will be calculated in Havana City, Cuba, during the equinoxes and solstices, as well as the variation that exists during the different seasons of the year. A study was carried out every 3 hours: 6am, 9am, 12m, 3pm and 6pm, (average solar time) creating a table with real values of this energy, obtaining maps of light and shadow planes.</p> ER -
