Preliminary study of the solar potential in the city campus University of the UNAH

Abstract

In order to determine the potential of the solar resource in the UNAH Campus on the roof of the E1 building, a CMP 6 pyranometer was installed to measure the global solar radiation on a horizontal surface, an SP Lite-2 Piranometer for measure the global radiation on a surface inclined at 14 ° facing south, a LOGBOX SD data logger, all of them from the Kip & Zonen brand and a DAVIS automatic weather station. The records of the meteorological parameters of interest were made in intervals of one minute. The data obtained was subjected to a statistical analysis that included daily and monthly averages, standard deviation, and  frequency distribution among others. The data shown in this study are those collected by the three pyranometers. Considering the measurement time factor, the data of greater reliability is that of the weather station DAVIS, since it has been recording data for three consecutive years, however, the data obtained by the Kip & Zonen pyranometers have been recorded only for eight months. This work shows us that the average daily solar radiation per year available in the UNAH Campus, 4.21 kWh/m2, is similar to the results obtained, for the central region of the country through the SWERA Project that indicates a value between 4.5 and 5.0 kWh/m2/day, and with 4.869 kWh/m2 daily average, measured with an Eppley PSP pyranometer in the UNAH in the period 1985-1990 and 5.01 kWh/m2 in daily average for a period of 8 months with a Kip & pyranometer Zonen CPM 6.
