Products Description


What is a bypass diode?
Bypass Diodes are connected in photovoltaic arrangements for the protection of such cells that are completely under the solar light and working properly from such cells that are not working or not in the solar light.
The principal fact of the power failure of the solar cell is the shading, that reduced the quantity of the light coming to the light. Shading can be due to some tree, wall of the house, or any other building.
If the shading remains on some cells of the panel there will be less power generation through this panel.
So how can we protect a photovoltaic cell, panel or even a full array from the destructive effects of partial or full shading. One simple and effective way to protect photovoltaic cells from against the destructive effects of cell shading is to connect what is called a Bypass Diode across each PV cell of a series-connected string.
Bypass diodes are connected externally and in reverse parallel with a PV cell to provide an alternative electrical path for the generated current to flow as it cannot flow through the cell when shaded. This helps preserve the performance of the series string by restricting the reverse bias voltage generated across any partially shaded cell and hence reduce the electrical power which can be dissipated by the cell.




Why a bypass is needed in pv modules?
Solar Cell Protection: Protection from Hot Spots of the single solar cells due to high reverse voltages in case of in case of shading .
Fire Safety: Protection from electric arcs within the module due to cell breaks or cell interconnection
breaks.
Energy Yield: Bypassing the shaded areas of the module.




XND19
XND19 is a new type of embedded bypass diode, which is directly embedded in the solar panel and does not need to be used in the solar junction box. It can reduce the volume and materials of the solar junction box and save the cost.It can be used together with gzx202 junction box, and only two smaller junction boxes are required. >>Click to Buy GZX202 Junction Box<<
Like traditional Schottky diode, realizes bypass rectifier function. The XND19 has even lower forward voltage drop and reverse leakage current than traditional Schottky diode, can take directly the place of the Schottky bypass diode used to prevent the hot spot effect currently.
