Analysis of Overcurrent Occurrence in Photovoltaic Modules With Overlapped By-Pass Diodes at Partial Shading
This paper investigates the problem of overcurrent occurrence due to partial shading in photovoltaic (PV) modules with overlapped by-pass diodes. Although this configuration is less common in the photovoltaic module industry, but it behaves unusually and interestingly at partial shading. These types...

| description | This paper investigates the problem of overcurrent occurrence due to partial shading in photovoltaic (PV) modules with overlapped by-pass diodes. Although this configuration is less common in the photovoltaic module industry, but it behaves unusually and interestingly at partial shading. These types of modules produce overcurrent at some shading profiles. In this paper, the possibility of overcurrent occurrence is estimated for photovoltaic modules and arrays. The maximum value of overcurrent is also calculated. The theoretical outcomes are verified by experimental results. The results can be used as a suggestion for appropriate wiring system selection. |
