Solar panels charge capacitors

Introduction In principle, solar panels can charge capacitors. But in reality there remain many unresolved problems. The “amount” of charge stored in a capacitor is not only related to its capacitance, but also to its terminal voltage.

Solar panels charge capacitors

In principle, it is possible. But in reality there remain many unresolved problems.

The “amount” of charge stored in a capacitor is not only related to its capacitance, but also to its terminal voltage.

If the voltage and current produced by your solar panel meet the charging and discharging conditions of the capacitor at the same time, then there is no problem to connect directly!

p>If you have selected The capacity or voltage of the capacitor cannot be satisfied by the solar panel, so a corresponding prefabricated circuit board must be designed.

It is best to use a solar panel to charge the battery. A constant current charging circuit is required to charge the battery. Generally, the solar panel current is very small and it will change with the current. the intensity of the light, so a constant current charging circuit is necessary. A charging circuitcurrent is used to charge the battery with a low current, then the battery powers the motor. At this time, a current limiting circuit is required. The current limiting circuit is determined based on the rated operating current of the motor. Firstly, constant current can be created by using the LM317 as a constant current source to charge the battery, the rear can also use the constant current from the LM317 to power the motor. Motor if cost is required. This will not cause the motor speed to change with current size. For the specific use of LM317, search Baidu for the connection method and information of each pin function, this is my solution. .What are the V and current of your solar panel?

The current of the solar panel is very small, and the charging and discharging current through the capacitor is also relatively small, and the rotationis unstable

10UF is not possible, it is recommended to use batteries

You list the specific parameters, solar panel parameters, motor parameters< /p>
