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. $$Energy=Capacitance×Voltage^2/2$$
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. Until the capacitor has charged to at least the forward voltage of the LED, the LED is not going to light
When putting the solar panel very close to a source of light this 0.4 value slowly rises up. I think you are right, i have a second solar pannel i might try to use both to charge it, I saw some people talking about a diode to not let the current flow back to the solar panel is this right ? A discharged capacitor is, essentially, a short circuit.
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.
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.
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.
In the constantly evolving realm of energy storage technology, the emergence of the solarcapacitor, also known as the solar supercapacitor, is causing a significant stir. This groundbreaking device symbolizes the dawn of a new era, offering an avant-garde approach to harnessing and storing solar energy.

The simplest solar-powered circuit to charge a supercapacitor is made by just connecting the capacitor to the solar panels. The only other important component is a diode to stop the supercapacitor from discharging back into the solar panels. The diode should have a low forward voltage drop like a Schottky diode.
Assemble the supercapacitor car with the solar panel, according to the instructions, adding wheels and the gear that connect the motor to the wheels. Repeat the experiments above, charging the motor for various times. As a measure of how much energy the capacitor is holding, measure how far the car goes on a flat floor out of direct sunlight.
Solved Two capacitors, 5 Farad and 12 Farad, are connected . Two capacitors, 5 Farad and 12 Farad, are connected in series. This combination is then connected in parallel to a 4.2 Farad capacitor. What is the equivalent combination (in units …
Wiring them in series increases the Voltage they can handle, but reduces the capacitance, so you get a 0.5F capacitor that is safe up to 32V. If you wire them in parallel, you get a 16V 2F capacitor, and mind bending amounts of current (the internal resistance is halved again to 0.001 Ohms, giving a short circuit current of up to 16,000 Amps!).
The dc power is converted to ac via inverters. The inverter technology may be in the form of either a single microinverter connected to each solar panel or a string inverter, which converts the accumulated power of multiple solar panels, wired in a series configuration. Within each inverter, film capacitors or long-life electrolytics find use ...
Two 1000 Farad capacitors in series = 500 Farads every day of the week. Are you sure you are an engineer.? Even an Electrician knows this. I think you need to go back to school and learn capacitors start here. Here is your first lesson When you connect capacitors in series, the result is that the effective plate surface area decreases, thus capacity loss. When you add batteries in …

Enhancing Solar Panel Efficiency with Capacitors. The integration of capacitors into solar power systems stands as a potent strategy for enhancing their efficiency and operational longevity. Capacitors, essentially energy storage components, function by storing and swiftly releasing electrical energy.
Therefore it''s better to charge the cap with a (5-6volt) solar panel directly (= current source). And use a shunt regulator across the solar cell (not across the cap), set to 5volt. If you use a buck/boost converter, then think several hundred Farad (of a good brand). Idle current of the converter could drain 18mF in minutes.
So I have a capacitor being charged by a solar cell which has a varying (but readable) power output. This is being fed directly into a 10 farad cap with a solar panel voltage of about $2.8V$. For the sake of this question let''s assume the output of the panel is $5mW$. Also, at the time of calculation, the voltage on the cap is known.
The 9v 300mA MAX solar panel is charging a set of three super series super capacitors. The 1N5819 diode blocks power from entering back through the solar panel. The charge off the super capacitors enters into a 3v regulator that …

D2 limits reverse current flow back from the capacitor through D1 or the solar panel, when there is not enough sunlight. (The reverse current through D1 was quite high at 5V). Testing seems to show that it works OK, in fact in direct sunlight the voltage at the processor 5V pin was getting up to 5.2V.

I''m doing the first tests for a project to power an ESP12-F with a solar panel and supercapacitors, without batteries. The ESP will be in deep sleep most of the time. For my first approach I built this, still incomplete but a first proof of concept: It works but only when the capacitors are almost full, I''m not sure why. The idea is to replace the four capacitors by one …
