Diseño construcción de un sistema de enfriamiento superficial de paneles fotovoltaicos mediante corriente de aire

The present work shows the design and construction of a surface cooling system for photovoltaic panels through air current as one alternative to reduce the functioning temperature and thus improve the voltage and operating efficiency. The research consisted of making a comparative analysis between two solar panels with the same technical characteristics and under the same functioning conditions to evaluate the system's efficiency. Three aspects were considered to identify the operating criteria of the system: the energy balance of one of the photovoltaic panels under study based on the data of its technical data sheet; the search for bibliographic information about the cooling technologies applied to these systems and based on the meteorological information of the study site. The construction of the cooling system is carried out based on previous design calculations of the various mechanisms, parts and pieces; the standardized elements used were chosen based on the strength of the materials, availability and costs. The validation of the prototype is done through an analysis of measurements and monitoring of surface temperatures, open circuit voltage, wind speed input and output of the system, and radiation, in this way it obtains the maximum generation powers for each panel, its validation is realized with the calculations of the theoretical solar cell temperature by applying the Mattei method, whose relative error is 4,74% of the measured data in relation to the calculated data Keywords: photovoltaics, cooling, temperatures, radiation, power, efficiency.
