CORRELACION ENTRE LA EFICIENCIA DE UN PANEL SOLAR Y LAS CONDICIONES MEDIO AMBIENTALES POR EL METODO DE REGRESION LINEAL MULTIPLE PARA LA CIUDAD DE TUXTLA GUTIERREZ (CORRELATION BETWEEN THE EFFICIENCY OF A SOLAR PANEL AND THE ENVIRONMENTAL CONDITIONS BY THE MULTIPLE LINEAR REGRESSION METHOD FOR THE CITY OF TUXTLA GUTIERREZ)
Resumen
En el presente trabajo se establece una ecuación de correlación entre la eficiencia de un panel fotovoltaico y las variables del medio ambiente irradiancia, temperatura, y velocidad del viento. Para establecer la correlación se usa el método de regresión lineal múltiple a partir de mediciones en horarios pico. Un cambio drástico en la irradiancia, producto de la presencia de nubes durante las mediciones, ocasiona un transitorio en la gráfica de la eficiencia: aparece un pico ó un hueco, o ambos. En este trabajo se demuestra que la aplicación de la técnica de regresión tiene un efecto de tipo filtro digital, los picos o cambios abruptos en las figuras de la eficiencia de la medición, desparecen en la gráfica de la ecuación de regresión lineal. También, cuando hay ausencia de cambios abruptos la grafica de la curva de regresión se aproxima más a los datos de la medición.
Palabras Clave: Eficiencia, irradiancia, panel solar.
Abstract
In this paper, a correlation equation is established between the efficiency of a photovoltaic panel and the environmental variables irradiance, temperature, and wind speed. To establish the correlation, the multiple linear regression method is used from measurements at peak hours. A drastic change in irradiance, due to the presence of clouds during the measurements, causes a transient in the efficiency graph: a peak or a gap appears, or both. It is shown that the application of the regression technique has a digital filter type effect, the peaks or abrupt changes in the figures of the measurement efficiency, disappear in the graph of the linear regression equation. Also, when there are no abrupt changes, the graph of the regression curve is closer to the measurement data.
Keywords: Efficiency, irradiance, solar panel.
