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.
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.
