Madrid, January 15, 2025 – Enertis Applus+ successfully implemented an innovative daytime electroluminescence technology during the development of the first pilot of EDP’s AutoPV project in Peñaflor, Valladolid. This pioneering project in Spain stands out for its use of automation technologies in the installation of solar modules, marking a significant advancement in process automation in the PV sector.
During the construction of the solar plant, an automated mounting system designed by COMAU was incorporated, optimizing the installation of solar modules. We conducted specific tests to verify that the installed modules maintain their integrity and performance, ensuring the success of this innovative mounting method. These tests were carried out with an advanced daytime electroluminescence system that allows for the detection of possible defects in the modules without the need to disassemble them, optimizing time and reducing operational risks.
José Manuel Rivas, Global Operations Manager of the Testing & Optimization at Enertis Applus+, commented: "In projects that employ new mounting methods, ensuring the quality of the modules is essential to guarantee the long-term performance of solar PV plants. Automation offers great advantages in efficiency and sustainability, but it is crucial to verify that the mounting process does not compromise the integrity of the components. At Enertis Applus+, we value the importance of R&D to support our clients and the sector as it keeps evolving. This development demonstrates our commitment, and we are proud to contribute our expertise to ensure the success of these innovations."
Daytime Electroluminescence: Innovation in Solar Module Inspection
For this project, Enertis Applus+ employed an innovative quality inspection system developed in collaboration with the GdS Optronlab research group at the University of Valladolid within the framework of an R&D project funded by the Center for Industrial Technological Development (CDTI). This pioneering device allows for daytime electroluminescence testing in environments with solar radiation, without the need to disassemble the solar panels, offering multiple advantages:
This technological advancement optimizes the daytime inspection of solar modules, facilitating the detection of defects such as cracks, fissures, or faulty contacts between cells.
The system uses near-infrared sensitive cameras and special acquisition procedures, allowing for electroluminescence testing even under sunlight conditions. Additionally, the device is controlled by a micro PC and can be operated from any Android device, making it easy to use in the field.
Tests conducted with this prototype have demonstrated its efficiency and competitiveness, achieving inspection rates of up to 80 panels per hour with images comparable to those obtained in the laboratory. This represents a significant improvement in quality control processes, allowing for mass inspections in real operational conditions during the day and reducing the need for nighttime work.
