The ESP8266 can be powered with 5V via USB, as well as with 3.3V. In order to achieve a long battery life, we use 3.3V and corresponding batteries with a higher voltage. Then we throttle it. The solar panels should deliver at least 5V, 6V is better. I recommend that each solar module can deliver at least 500mA (better 750mA).
Connect the solar panel leads to the solar terminals. Place the solar panel outside in direct sunlight. Confirm that the red CHG light turns on. Your solar panel is now charging your 3.7V battery. All that''s left to do is connect the Arduino. Step 3: Plug the Arduino into the USB Port. Plug your Arduino into the USB port on the Solar Power ...
Step-down voltage regulator: this is used to lower the voltage of the solar panel to 5v; Step-up voltage regulator: this is used to bring the battery''s voltage of about 3.7v to 5v, which is the voltage the ESP32 needs. For boards with the microcontroller running at 3.3v, we could directly bring the battery voltage to 3.3v, although this is a ...
Powered with solar panel, the circuit will give you 5V pure regulated DC voltage. This solar cell power supply circuit is made up of an oscillator transistor as well as a regulator transistor. The solar panel charges the battery when sunlight is bright enough to generate a voltage above 1.9v.

While daytime, the solar cell generates a voltage higher than the battery voltage, therefore current is flowing into the battery. When the cell is covered or it''s nighttime, the voltage across the cell is 0V, so the battery, with it''s higher voltage, would try to feed current into the cell, therefore draining and possibly damaging the cell.
U1A compares an adjustable sample of the present battery voltage to a 5V reference from a highly stable source. According to the result, it controls the power transistors Q1 and Q2, which shunt off the excess power generation from the panel. A diode (D1) avoids battery voltage to go back to the panel under no-light condition.

A linear voltage regulator converts your voltage by dissipating the remaining as heat. What this means is that in your application the heat dissipated is (InputVoltage - OutputVoltage)* Current Supplied = (12-5) * 1 = 7W!!!! Now that is a large amount of heat that you will need to dissipate, so you will definitely need a heatsink and …
Input voltage 1.5V Output voltage 4.88V - 4.97V Input current around 250mA. Input voltage 2.5V Output voltage 4.95 - 5.05V Input current 100mA. Conclusion: All of these DC-DC Boost converters did work, although they failed at the low end at 0.9-Volts input, which I expected. Input current was high at 250mA for the lower input voltages.

The voltage from the solar panel(s) will not only vary with luminosity but also with load, as when you draw current from a PV, its voltage drops. So you want a module that will deal with nearly any incoming voltage (search eBay for boost buck module) and output a relatively stable 5v to charge either a power bank or a lithium cell via a tp4056 ...
