BLOCKING DIODES A blocking diode is required in each ''series string'' of solar modules between the modules and regulator/battery, to prevent current flowing back through the modules when the modules are shaded or during darkness. The blocking diode acts like a one-way valve, allowing current to flow only one way, out of the solar module.
Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren''t an optional component that delivers increased efficiency.

Identifying a Blocking Diode. To check if your solar panel has a blocking diode, look for these signs: Check the terminal box of the solar module. The blocking diode is usually located at the positive end of the series string inside this box. Examine the configuration of the diodes. Blocking diodes are connected in series with the solar panel.
As the name suggests, bypass diodes are used to bypass shaded solar cells. They stop shaded, high-resistance cells from getting ''hot spots'' and reduce the power loss in the partially shaded panel. How Bypass Diodes Work In Modern Solar Panels. A modern solar panel is typically 132 half-cells connected in series.
