Abstract

In order to develop future projects in the field of photovoltaic solar energy, it is essential to accurately know the potential solar resources. There are many methods to estimate the incident solar radiation in a certain place. However, most of them are very expensive or do not have the ideal characteristics for good monitoring of a particular photovoltaic installation. For these reasons, an electronic device connected to the internet of things (IoT) is presented in this paper which manages to measure global radiation in photovoltaic applications. The device developed has been patented in the Spanish Patent and Trademark Office. It presents some features that make it very suitable to measure photovoltaic installations with the advantage of being a low cost and very reliable device. The device has been tested to determine global horizontal irradiance obtaining a correlation coefficient R2 = 0.994.

Highlights

Renewable energies have proven to be very reliable energies for the future world energy scenario.There are many such energies, and the degree of technical and economic maturity of all of them is very varied, in general they are all very technologically advanced and are beginning to be, or already are, fully competitive economically against “conventional” energies [1].The growth of the installed power capacity of renewable energies during the period 2001–2015 can be seen in Figure 1, obtained from the International Renewable Energy Agency (IRENA) 2017 report [2].It is noteworthy that, from 2012, the accumulated power of renewable energies began to be higher than those of non-renewable energies, and continues
It can be seen that the global horizontal irradiance (GHI) and acquires and transmits it using an internet of things (IoT) channel to be integrated into the monitoring system of a photovoltaic photovoltaic generator
Among the methods for obtaining the global solar radiation reviewed above, it can be highlighted that the two methods most commonly used in research are pyranometers and methodologies based on the use of satellite images, both due to the quality of the data from solar radiation obtained with them
