Currently, I have two diodes: one diode is connected to a solar panel, and the other is connected to a 14V DC input. When the voltage of the solar panel drops below 14V, the DC power supply provides the current. Once the solar panel voltage rises above 14V, the current produced by the panel is supplied to my charger.

A solar charger circuit does lower the power, and the output voltage also decreases. The minimum output voltage required to charge a 12V battery is 13.6V. Therefore, during lower solar strength, the load becomes zero. The solar charger circuit demonstrated below does not produce impressive results but offers a reasonable output with low voltages.
Solar battery charger operated on the principle that the charge control circuit will produce the constant voltage. The charging current passes to LM317 voltage regulator through the diode D1. The output voltage and current are regulated by adjusting the adjust pin of LM317 voltage regulator. Battery is charged using the same current.
