Automatic Real-Time Defect Detection and Analysis in Solar Cell

Overview

For good efficiency, fast, reliable, and smooth operation of any process we need a failure-free operation. It gives high production and also ensures a high return on investments. A failure-free operation is of fundamental importance for modern commercial solar power plants to achieve higher power generation efficiency and longer panel life. So a simple and reliable panel evaluation method is required to ensure good efficiency.

Identification of fault, its detection, protection, and fault analysis are necessary to prevent unexpected events in solar photovoltaic (PV) systems. In spite of the fact that Solar PV systems have no moving parts and generally require low maintenance, they still have a greater number of chances to get various failures or faults along with the PV arrays, PV modules, batteries, wiring, and power conditioning units and interconnections to the utility. It is difficult to shut down PV modules completely during faults since they are energized by sunlight in the daytime. Also, PV is modular technology in which a PV power plant can be made by connecting many PV modules in series and parallel configuration. Once PV modules are electrically connected, any fault among them can affect the entire system performance. In a large PV solar module, it may be very difficult to properly identify or detect a fault. It can remain hidden in the PV system or unidentified until the whole system collapse or breaks down.
