System and method for identifying defective solar panels and to quantify energy loss

A system for performance monitoring of at least one solar panel of a solar power plant, the system comprises:

• at least one aerial vehicle to capture visual images and thermographic images of the at least one solar panel;
• a data-processing arrangement in communication with the at least one aerial vehicle via a communication network, wherein the data processing arrangement is configured to:
• receive the visual images and the thermographic images of the at least one solar panel of the solar power plant;
• stitch the received visual images and thermographic images of the at least one solar panel to create a visual orthomosaic image and a thermographic orthomosaic image respectively;
• create visual signatures and radiometric signatures of the at least one solar panel using the visual orthomosaic image and the thermographic orthomosaic image respectively;
• create at least one table with coordinates in the thermographic orthomosaic image, wherein the table comprises at least one string of solar panels of the solar power plant;
• create a table-to-string mapping by assigning at least one string data of the at least one string of solar panels with the created at least one table;
• identify at least one defect in the at least one solar panel in response to the created visual signatures and radiometric signatures, by processing the at least one string data mapped in the at least one table;
• calculate energy loss in each of the solar panels of the at least one string of the solar panels in the solar power plant for performance monitoring of the at least one solar panel.
