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. (Increasing DC voltage is very inefficient so go for regulating it down). This is because a capacitor voltage drops as it discharges energy. $$Energy=Capacitance×Voltage^2/2$$

Here, (C) is the capacitance in Farads and (V) the voltage. It''s unlikely you can use the energy until the capacitor is fully discharged. So the usable energy is more likely to be the difference between the initial voltage and the voltage at which the load stops working: [E = frac{1}{2}C({V_f}^2-{V_i}^2)] For example, some microcontrollers brown-out at 1.8V.

6 FAQs about [Capacitor voltage stabilization for solar panels]

How to calculate the charging-discharging of a solar panel capacitor?

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.

Should I use a resistor or a capacitor for a solar panel?

The resistor is useless. Your solar panel already has a voltage decreasing when current increases (that is, it is not an ideal voltage source,) and the maximum current your small panel produces should be no issue at all for the capacitor. There is no reason to dissipate power as heat The 1N4148 diode you use is not adapted for your application.

Does a PV system with two supercapacitors affect grid stability?
