Solar Irradiance Measurements Using Smart Devices: A Cost-Effective Technique for Estimation of Solar Irradiance for Sustainable Energy Systems

Abstract

Solar irradiance measurement is a key component in estimating solar irradiation, which is necessary and essential to design sustainable energy systems such as photovoltaic (PV) systems. The measurement is typically done with sophisticated devices designed for this purpose. In this paper we propose a smartphone-aided setup to estimate the solar irradiance in a certain location. The setup is accessible, easy to use and cost-effective. The method we propose does not have the accuracy of an irradiance meter of high precision but has the advantage of being readily accessible on any smartphone. It could serve as a quick tool to estimate irradiance measurements in the preliminary stages of PV systems design. Furthermore, it could act as a cost-effective educational tool in sustainable energy courses where understanding solar radiation variations is an important aspect.

Linear Quadrupole Magnetic Field Measured with a Smartphone

“…Mobile devices can provide meaningful assistance to users in their work, study, and entertainment. They have been widely used in recent years within the process of instruction in different disciplinary fields, [4][5][6][7][8][9][10][11][12][13][14] although the effects on learning and the purpose given to them in the classroom are still being studied. Furthermore, smartphones are becoming the data recorders of portable physics laboratories for a variety of measurements in astronomy, mechanics, thermodynamics, electromagnetism, and optics among others, either using the internal sensors of cell phones or diverse applications.…”

“…with the use of "smart" devices, in which combined use of new engineering solutions, small scale computers, sensors and software allows for a significant reduction in power, time and resources needed for operations [1,2]. An important aspect of "smart" devices is improved comfort and freedom of the user.…”

“…The accuracy of weather measurement is known to be intermittent, and a sudden and large unexpected variation can negate a forecast. The accuracy sensor measurement of solar irradiance intensity and the temperature are factors that influence the forecast accuracy of solar PV power generation [ 6 , 7 ].…”
