You can look up an I-V curve of any solar panel to see how it works. So, depending on your load, your panel will output around 5 volts approximately, but that tp4056 tends to try to charge lithium batteries at 1000mA rate and when it tries to draw that high of a load from your panel that can only produce around 150mA at best
Customer ServiceP.S. you have a 1 watt solar panel hooked to a dc-dc booster which might be 85% efficient, then the tp4056 bucks it down to the 3-4.2 volts that the battery needs, losing another 15% at least due to inefficiencies. So the max 1W panel can supply only 0.73 Watts to your battery under ideal conditions - a modern 18650 cylindrical lipo is easily 10 Watt-hours
Customer ServiceI have a 250mA 6V open circuit solar panel which I hooked up directly to a TP4056 board only to discover that this would only charge to about 3.6V after lowering the charge current I can get the battery to about 3.8V. So I decided I needed to do some more reading .
Customer ServiceEl poder del Sol: Descubre el panel solar 6V y su contribución a la energía renovable. El poder del Sol es innegable en el contexto de la energía renovable.Uno de los dispositivos más importantes para aprovecharlo al máximo es el panel solar 6V. Estos paneles utilizan celdas fotovoltaicas que convierten la luz solar en energía eléctrica de manera eficiente y sostenible.
Customer ServiceI also have a 12v panel I could use, but the TP4056 has a max input of 8v (some sources say 6v). The other thing I have considered is putting another battery in parallel to give a max of 7.5v when charged. I have a spare
Customer ServiceThe TP4056 is not ideal for such a circuit, but I worked out a solution that seems to work fine, as shown below. But be mindful of the maximum voltage tolerated by the TP4056 and the op amp. A "5V" panel usually works, but a 6V panel''s maximum voltage may be too high. Note the orientation of the P-channel mosfet, which seems
Customer ServiceIn this article we''ve shown you how to power the ESP32 or the ESP8266 with solar panels, a lithium battery and a TP4056 battery charger module. The circuit we''ve shown you can also be used to power other microcontrollers that require 3.3V to operate. When powering the ESP32 using solar panels or batteries, it is important to save power.
Customer ServiceToday I will show you why you should not use a solar panel directly with TP4056 Li-Ion battery
Customer ServiceIdentical-ish 6V panels, ESP8266es, lora transceivers, Samsung 18650es, buck-boosts, and side-by-side in a field. Oct 1 is the end of the experiment, but there''s not a significant difference. The batteries top off within a few minutes of each other. That''s unexpected, but is what it is.

Customer ServiceI would like to match solar panel (6 V1000 mA) to charge controller based TP4056 in order to charge 18650 battery around 3200 mAh.
Customer ServiceIt means that if your battery is ~4V and your solar panel is ~6V you are wasting around 2V*current as heat. Even if you manage to extract the maximum from the panel, the energy loss is high. Consider using a switching regulator, or make your own (buck) with atmega, it is a simple circuit and can have an efficiency of about 90% in any load case

Customer ServiceThe tp4046 can be used to charge the battery with a solar cell while running on the battery. I found 6 V''s to the TP4056 to works better than 5V to the TP. The TP will wear out the batteries in about 4 to 6 months and Li does not work well when temps turn freezing. Just connect the load to the TP output.

Customer ServiceThanks for fast reply I can consider to use to 18650 in parallel and a bigger 6V panel lat delivers enough amps easier. But the lights i linked to uses only one 2.200mAh 18650 for each lamp and the solar panel is 6V and around 3W. That will work fine in sunny areas and in Norway when it''s summer. But maybe not perfect when it''s winter with 12
Customer ServiceThis helps extend the time I can charge the panels by a few minutes. At some point, the buck converter can''t supply 5V and enough current to the 4056 and it switches to battery power. The ESP8266 (an Adafruit Huzzah board) only wakes up from deep sleep once a minute to collect data, but it can run off a 18650 for about 4 days without a solar

Wire the solar panels to the TP4056 lithium battery charger module as shown in the schematic diagram below. Connect the positive terminals to the pad marked with IN+ and the negative terminals to the pad marked with IN-. Then, connect the battery holder positive terminal to the B+ pad, and the battery holder negative terminal to the B- pad.
Today I will show you why you should not use a solar panel directly with TP4056 Li-Ion battery charger, and how you can use solar panel with TP4056 Li-Ion battery charger. The problem - I wanted to use a float sensor to measure the level of water in my overhead tank. It has three wires coming out of it.
I could use the Arduino to monitor the solar panel voltage and regulate the TP4056 current with the following circuit: Rprog and Rarduino would be 600 ohms and the 100uF capacitor and Rarduino will act as a low pass filter for the Arduino analog out that output a 3.3V 500Hz PWM signal.
You don't autoregulate a TP4056 for maximum solar power extraction. MPPT is only applicable to switching DC-DC converters (not lineal). TP 4056 is a lineal charger and input current is roughfly equal to battery charge current no matter what you do.
I also have a 12v panel I could use, but the TP4056 has a max input of 8v (some sources say 6v). The other thing I have considered is putting another battery in parallel to give a max of 7.5v when charged. I have a spare L7805CV voltage regulator I could put on the output but fear that would produce a constant battery drain.
