When you charge a capacitor using a solar panel there are a number of problems that need to be addressed: If you connect a capacitor directly to a solar panel the capacitor will be charged when there is light, but when it becomes dark the opposite will happen and the capacitor will be discharged into the solarpanel.
A discharged capacitor is, essentially, a short circuit. So connecting a discharged capacitor will short-out your solar panel, until the capacitor voltage rises as it charges. With a supercapacitor, it will take a very long time to charge - so the voltage will remain low for a long time.
The increasing demand creates the opportunity to increase production and enables solar energy storage for further use. Using capacitors with solar panels steadily changes the performance and longevity of the solar system. Solar panels produce energy from the sun, and the system converts DC to AC electricity.
For exact calculation of the charging-discharging of the capacitor, we would need: The link to the datasheet of your solar panel. Information on the load attached to it (link if possible, minimum and maximum voltage.) You'll have to get more than 3V out of your panels and more than 3V on the cap/battery to get some seconds of 3V 500mA out of it.
Yes, you can use capacitors with solar panels. But, only the supercapacitors are eligible to perform with solar panels. The supercapacitors can discharge the high-voltage current from the solar cells, which is much higher than the loading current. It will help the system when there is an intermittent load.
It seems to work fine, the supercap voltage appears to stabilise at around 2.85V with the panel pointed at the sun, full sunshine and the panels clean. Such ideal conditions will be rare though, the panel may be shaded most of the time. I know that an MPPT charger would be more efficient but I want this to stay as cheap and simple as possible.
Power ESP32/ESP8266 with Solar Panels and Battery
my solar panels are small, so to avoid "shorting" them I replaced R3 on TP4056 to 4k7 and it works this way: when ESP works and it needs <=300mA the power comes fully from battery. When ESP goes to sleep, total current from solar panel goes to charging – yes, slow charging, but I don''t mind. My ESP sleeps for 5min then it works for 8s ...

voltage
The easiest way is to charge the cap directly from the panel, with a circuit to disconnect the cap when its voltage reaches about 2.5 volts. A simple 2.5V zener diode regulator would probably be as effective as anything. If you a blocking diode as well to prevent current flowing back into the panel then you will be pretty much set.
