The article also provides step-by-step instructions on how to connect a diode to a solar panel, including testing the diode and best practices for installation.
Solar panels require a diode to prevent current flow from the battery to the solar panel when there is little or no light. For solar panels, a 3 amp or 8 amp diode can be used for this purpose. You might also want to install a bypass diode to prevent a shaded panel from drawing down other panels. These same diodes can be used.
When connecting diodes, it's important to ensure the cathode is connected to the positive terminal of the solar panel and the anode is connected to the negative terminal of the solar panel. In case you do the opposite, the current will be blocked, and your solar panel won't work. To connect the diodes, you need the following tools:
This larger diode can be placed in-line with the common positive wire coming from your solar panels to your charge controller to handle multiple panels at one time. Please note: This larger diode may require a heat sink if it will be used for higher power applications (above 15 amps or so).
You might also want to install a bypass diode to prevent a shaded panel from drawing down other panels. These same diodes can be used. Place diodes in an ABS project box. If you are using a solid state charge controller, such as the C150-SMA charge controller, you may not need a blocking diode. Does a diode come with your charge controller?
In a simple single module and regulator system, a separate blocking diode is not normally required since one is normally incorporated into the regulator. Whenever more than one module or a module and another charge source (eg wind generator) are directly connected in parallel, a blocking diode is required in each 'series string' of solar modules.
Therefore, the two main types of diodes used in a solar system are: A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from battery to solar panel thereby preventing the battery from discharging.
