Meteorological Solar Station in Chile
It's noon in Arica, when the sun lets itself feel all its strength on the city and although people avoid exposing themselves, there is a group of experts who do not plan to leave the torrid atmosphere. These are Renato Vallejos, project engineer; Marcos Cortés, logistical support and planner (both from WeGroup); the Spanish Oliver Galán, technical specialist in meteorological and environmental equipment from Geonica (company from that country) and Cristian D.. Fonseca, Computer Science Engineer at LIMZA, who are installing the equipment to operate one of the three field monitoring stations for the solar map project for Arica and Parinacota, which is financed by the Regional Government's FIC and executed by the Center for Research on Man in the Desert (CIHDE), on the roofs of the Velasquez Campus, north wing at the University of Tarapacá.
 

The professionals told that the tuning is not simple, since in this day they began their day at 6 in the morning to see where the star king appears and verify that there is no external element that can alter the record that should make the instrument that will provide transcendental information to clarify the levels of radiation that really has the region of Arica and Parinacota.
Basically, the equipment is divided into three parts: a sensor receiver with three sensors to measure solar radiation, an energy panel to guarantee its self-sufficiency and a small power station that receives the data from the equipment, which will then be processed and collated with satellite information; stations that will be on three regional levels: at sea level, 2,300 meters high and 4,000 meters above sea level.
Galán explained that global radiation is the sum of detecting lightning sensors in a direct way (focused directly on the sun, with open-air radiation) and diffuse (the one that is in the atmosphere without direct sun, but reflected by clouds and alternate factors, but with a constant shading device, which is moving).

We have the solar panel that serves to power the equipment and be autonomous, but the real heart of the system is where the sensors go, the solar radiation, diffuse (with a mobile shading mechanism) and the one that is going to read the direct radiation always focused on the sun, following its cycle, moving along its entire path; all these data are sent to the plant that stores data and makes the maximum and minimum calculations so that it reaches the reception center ",.
Meanwhile, Vallejos added that:"Groso modo is the measurement of radiation on two levels; to have better results there are 3 field monitoring stations in the region for calibration with the data obtained through satellite services that have already been performed.
On the equipment, the professionals agree that these are the same as those used in solar power plants in countries such as Spain and that they do not require greater care, other than proper maintenance of their sensors.
Finally, they affirmed that a priori there are good conditions in the region and that in this sense the project is very important for planning solar parks and so that the region of Arica and Parinacota and its territory can be projected in a planned and sustainable way.
