Solar irradiance is the magnitude used to describe the power density of solar radiation incident on a surface
expressed in Watts per square meter. The study and measurement of solar irradiance are important in applications related to the use of alternative energies
such as in the design of Solar Parks. There are diverse technologies and devices and techniques for measuring solar radiance
such as radiometers
the generation of maps of radiation based on photovoltaic elements
GPS applications
or geographic information systems. The principal limitations of these alternatives are the efficiency
high Installation and implementation costs
the need for control systems
high-energy consumption
complex designs
environmental barriers
and affordability
among others. In this work
a prototype has been designed to estimate the spatial distribution of the solar radiance on a specific location. The device consists of a cell array of mono-crystalline solar cells on a dome (semi-sphere)
a data acquisition system
and a communication system. The prototype can determine the values of solar irradiance incident in an array of solar photovoltaic cells arranged on a dome at different inclinations and orientations. Values of incident irradiance in each cell is measured indirectly by measuring the current of each solar cell. Subsequently
the data are transmitted to a computer (user or destination) for display and analysis. The transmission is carried out through two Xbee communication modules (transmitter and receiver) based on the IEEE 802.15.4 network protocol. This document describes the specifications for the design and operation of the device as well as the results of the preliminary tests. Compared to alternatives existing in the state-of-the-art
this device has the following advantages: standalone operation
ease of data transmission
robustness to changing weather conditions
ease of installation
different power supply options.
