The diode prevents current flow from the battery to the solar panel during night hours. The 18650 battery is connected to the Battery(+/-) pin and the TP4056 charge current to the 18650 with a regulated 4.1V level. (So output power from the solar panel is less than 4.1V, actually charging seems not occurring)

Solar Charge Controller displays different voltage than at battery
Because your panel meter has so few digits, there is a chance that''s 1% of reading +/- 1 count, if its ADC is 12 bits (one in 4096) rather than 10 or 8 bit. Some meters have 6 1/2 digits but are only accurate to about 4 digits (drift over time but useful to see small differences short term.)

Or take 500mA for 1s, from a 1F capacitor, it will drop by 0.5V. So if you took a 1F capacitor bank, rated not less than 6V, and put it across the input of your buck converter, then that should be enough to provide 500mA for 1S, only dropping from 5V to 4.5V in the process.

How to test solar panel condition and performance
As shown on the display, it reads 22.5V Voc, compared to the 23.3V labeled rating, we can say it''s close, the difference less than 1V. If they''re similar, so far your panel seems to be in good condition, which means the panel should work fine.

Force voltage to 5V or 0V from solar panel
The solar panel I have is described as 10W 12V, but it seems it can output less than 12V, hence the question about handling lower voltages. Yes, 10W at 12V is what it''s going to produce under ideal conditions -- that means something approaching bright sunlight (if it''s properly specified it''ll tell you at what irradiance it delivers that amount of …

How to Read Solar Panel Specifications | altE DIY Solar Blog
It starts to get tricky when you move away from battery based solar systems, and the 12V increments are no longer necessary. Grid tie solar panels with 60 cells are often referred to as 20V nominal panels, like the Heleine 360W black monocrystalline solar panel.. They have too high of a voltage to charge a 12V battery …
Is this real? No charging until PV > BAT +5V?
The MPPT can bring the output voltage lower than the PV voltage, not higher. The advantage (over PWM chargers) is that you can use a PV array with higher voltage to charge a battery with much lower voltage.

MPPT 100/20/48 always keeps Vpv 5V above Vbat. Supposed to be 1V…
That is not problem. After starting Vpv should stay 1V above Vbat to keep charging. " PV voltage must exceed Vbat + 5V for the controller to start. Thereafter minimum PV voltage is Vbat + 1V." What i see in the VE connect app is that the MPPT always keeps Vpv aprox. 5V above Vbat. This causes the battery to not charge completely.
