DAVILA-SACOTO, Miguel Alberto et al. Low-cost infrared thermography in aid of photovoltaic panels degradation research. Rev.fac.ing.univ. Antioquia [online]. 2021, n.101, pp.20-30.  Epub Sep 14, 2021. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.20200689.

The analysis of PV solar panels deterioration allows researchers to know the health status of a panel in order to determine the overall functioning of a PV solar farm. A part of this analysis is performed by thermography, generally using professional and expensive equipment. This article presents a validation for the use of low-cost thermal imaging cameras, reviewing the relative error that can be obtained through scattering, contour analysis and three-dimensional meshes. The procedure is validated by analysis of I-V/P-V curves and a temperature sensor matrix, reaching errors less than 10% with cameras with less than 500USD.

Keywords : Thermography; low cost; thermal camera; image Processing; temperature sensor.
