Global solar radiation, assessed using a pyranometer placed on an inclined plane

Abstract

The city of Zacatecas, due to its geographical location, a city with little industry, neighboring the Tropic of Cancer and a height of the order of 2,492 above sea level, has the conditions for a study of the behavior of solar radiation and its possible potential use to transform it into other types of energy. The objective of this work was to have an irradiance database in the city of Zacatecas using CMP 22 Kipp & Zonen pyranometers from Campbell scientific, in order to satisfy the needs derived from radiation-related industry activities. The pinanometers are located at the Zacatecas_04 Solarimetric Station, which is located on the UAZ Siglo XXL Campus in building 6 of the Academic Unit of Chemical Sciences of the Autonomous University of Zacatecas (Lat: 22°46'21.01''N, Long: 102°38'37.14'') in the city of Zacatecas, Zac, and is part of the Mexican Solarimetric Network promoted by the Mexican Solarimetric Service of the Institute of Geophysics of the National Autonomous University of Mexico. The data was rearranged into hourly, daily and monthly averages. The average daily irradiance was 547 ± 5 W/m².
