I want to use small solar panels to charge a supercapacitor, and the cap then serves as an energy reservoir in the absence of full sunlight. I have already set up a basic circuit with a EDLC supercap (VINAtech, 100F, 3V), a small solar panel (3V, 270mA) and a …
Get PriceUnless the solar panel is tiny, it is strongly advised to utilize a solar charge controller when connecting a solar panel directly to a battery. Generally speaking, a 5-watt solar panel can be directly attached to the battery terminal, but anything more significant requires a solar regulator to prevent the battery from being overcharged.

Get PriceDuring the day, when the sun shines on the solar panel, the current from the solar panel enters the TP4056 and charges the battery, and the output will be fed directly from the solar panel, because with the two diodes the higher voltage is "passed through". In fact, the voltage of the regulator, which is 5v, is higher than the 4.2v of the battery.
