Research on PV module structure based on Fault detection
As to detecting the occurrence of Hot Spot, this paper presents a new type of photovoltaic (PV) arrays connection: CTCT structure (complex-total-cross-tied array). In the array of CTCT-type PV cells, by adding a certain number of current sensors and comparing the current, we can find the location of PV cells that have Hot Spot. This paper derives a formula to demonstrate the relationship between the total number of solar panels in parallel, the resolution and the total number of current sensors. We can detect the precise location of PV cells that have Hot Spot by using current sensors as few as possible.
