Show Summary Details


The sun is the more plentiful source of natural power that we have in the Earth. However, the amount of radiation reaching the Earth's surface depends on astronomical and climatic factors. One of the factors exerting a greater influence is cloudiness. For that reason, it is important to quantify its influence on solar radiation. According to that, in this work, a prototype to capture images of the celestial vault is designed and implemented to be able to measure parameters related to the cloud properties and, later, to determine their influence on solar radiation.
