For example, if you're using a 12-volt solar panel to charge a 12-volt battery, you'll need a diode with a reverse voltage of 24 volts. The reverse voltage determines the amount of power that can be dissipated by the diode. If you're working with high voltages, you'll need to choose a diode with a higher reverse voltage.
You can connect solar panels in series without using a diode. The diode is usually used to prevent battery discharge when it is dark. "mAh" is a measure of battery capacity. You are thinking of current, measured in A or mA. What i am trying to do is connect 3 solar panels (5V 250mAh) together to create at max 15V 750mAh.
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:
The diode must be able to handle the maximum current delivered by the solar panel to the battery. Measure that, and then consult the diode data sheets. Lithium batteries are very quickly destroyed by overcharging and over-discharging.
If you have a monocrystalline solar panel, you will need a larger diode than if you have a polycrystalline solar panel. This is because monocrystalline solar panels such as 150 Watt 12V Monocrystalline Solar Panel from Shop Solar Kits produce more current than polycrystalline solar panels.
If you want your project to last for more than one day, you need a solar lithium battery charger and discharge protection. The diode must be able to handle the maximum current delivered by the solar panel to the battery. Measure that, and then consult the diode data sheets.
