Industry Do I need diodes!!
If your charge controller is an MPPT type, you should be able to wire panels in series. If it''s a PWM type, you must use parallel wired panels. Bypass Diodes should exist in nearly all factory made panels. Your charge controller should provide the night time blocking action, and so I don''t think you need any extra diodes at all.

6 Frequently Asked Questions about “Solar panel plus a diode to charge the battery”
How do you charge a lithium ion battery with a solar panel?
You have the diode backwards. Connect the black end of the diode to the red wire from the solar panel, and the end of the diode with the silver band to the red wire of the battery holder. A 4.5V solar panel won't generate enough voltage to charge the batteries. Lithium ion cells have a voltage of 3.6 volts and higher.
Can I add a diode to a solar panel?
You can add a diode in series with the positive wire of the solar panel. It can be a 1N5402 diode The battery can be any 3.7V 1200mAh Li-ion battery. Motor can be any 3.7V DC motor.
What are the components of a 12V solar charging system?
Basic Components of a 12V Solar Charging System A basic photovoltaic (PV) solar electric panel system for 12V battery charging comprises a solar panel connected to a charge controller, connected in turn to the battery. PV Solar panels The amount of power that a PV solar panel provides is indicated by the wattage (W).
How do I choose a diode for a 12 volt solar panel?
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.
Can a solar panel charge a battery directly?
For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.
Should I connect a solar panel directly to a battery?
Connecting a panel directly to a battery is not a good idea for many reasons. A charge controller is nearly always recommended. Connecting directly (even through a solar panel blocking diode) can over charge the battery and severely reduce its life. It can allow the battery to become very low and again severely reducing the life.
