The asset assessment and condition monitoring of large-scale photovoltaic (PV) systems spanning over a large geographical area has imposed urgent challenges and demands for novel and efficient inspection paradigm. In
PV array for follow-up inspection. On-site inspection of a PV array shall start with a visual inspection of the cabling and the PV modules. This initial diagnosis can already give
The most common inspection techniques employed in PV plants for assessing the performance of PV modules include visual inspection, current-voltage measurements (I-V curves), thermographic imaging, and
Authors propose an approach aimed at increasing the energy efficiency of high-power solar power plants by automating the inspection procedures of the surfaces of photovoltaic modules. The solution is based on
The PV installer is a necessary part of the inspection process and should be required to open equipment and to operate equipment with the inspector observing the system during these actions. This inspection coupled with a
Our contributions lower the barrier to regular inspections of utility-scale PV plants, improving their reliability, safety, durability, power output, yield, and profitability, which is
the inspection procedures of the surfaces of photovoltaic modules. The solution is based on the use of an unmanned aerial vehicle with a payload capable of video and geospatial data
This paper presents a review of imaging technologies and methods for analysis and characterization of faults in photovoltaic (PV) modules. The paper provides a brief overview of PV system (PVS) reliability studies and monitoring approaches where fault related PVS power loss is evaluated.
The traditional inspection method involves maintenance personnel patrolling the entire PV plant for observing visual defects and/or capturing IR/EL images (using hand-held cameras or tripod system) for the detection of malfunctioning PV modules [ 10, 23 ].
Abstract: Condition monitoring and fault diagnosis of photovoltaic modules are essential to ensure the efficient and reliable operation of large-scale photovoltaic plants.
Visual inspection is a simplistic method utilised to spot colour changes and to detect visible PV module defects [ 6 ]. Delamination, discoloration, bending, glass breakage and soiling (e.g., dust, dirt and bird droppings) can be detected by visually inspecting PV modules [ 6 ].
The experimental results clearly demonstrate the effectiveness of our solution for photovoltaic modules diagnosis with multiple visible defects. Condition monitoring and fault diagnosis of photovoltaic modules are essential to ensure the efficient and reliable operation of large-scale photovoltaic plants.
The conventional approach to PV module inspection is to use a hand-held infrared sensor and perform visual inspection in-situ by a human operator. The main disadvantages of this method, when applied to a large-scale PV power plant, are that it is time-consuming and costly .
