Can I hook a solar panel to this?

A solar controller with +5v output is well advised, or alternately a 12v panel w/ 12v controller and then use a car 12v 1amp to USB converter.

I am considering connecting a solar panel to the charger. What is the maximum voltage the charger can tolerate?

The TP4056 chip on the board says in the datasheet a maximum of 8 volts can be applied to the chip. I don't have it on hand to check, but you can add the voltage drop of any components in series with the power input and T4056's Vcc. Example, if a reverse polarity protection diode with a drop of 1 volt was before the chip, the maximum goes up to 9 volts because after the diode, there is now only a 8 volt potential difference.

Will it cut the power when the battery reaches 3 volts?

Hi, Charging cut-off voltage: 4.2V ± 1%

What is the voltage on the Out pins?

about 5.1volts. I used these to power some Arduino Pro Mini projects using a single lipo18650 cell with good success. The output voltage is 5V regardless of input voltage or if it is running from battery. According to the chip datasheet you are not supposed to run a load and charge the battery at the same time but I had no problems doing so as long as the load was mild (<500ma).
