This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these
Voltage Regulator: ProTech 5 Volts Module. The 5310 is available in variants with output voltages of 10 and 5V for linear regulation or supplies for sensors or communication …
Your 12 volt solar panel will have a diode in series with it to stop voltage feeding back through the solar panel. So there is a 0.7 volt loss already, so you will get 11.3 volts from the panel. You should design for at least 50% higher voltage that your battery and then let the charge controller take care of matching the voltages.

Regulating voltage from solar panels : r/diyelectronics
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 module.
In this tutorial, I''ll run through 3 ways to solar power an Arduino (or Raspberry Pi). These methods all: Use a 3.7V or 12V battery Power the board via the USB port Require no soldering Let''s get started. 1.

Each cell has a nominal voltage of 0.5V so they call this a "5V" panel They output a nominal 5V at 940 mA peak via a 3.5mm x 1.1mm DC jack connector. The panel is constructed with ETFE (Ethylene Tetrafluoroethylene), making it extremely durable and resistant to environmental elements, a superior upgrade to PET or laminate solar panel construction.
The easiest way you can reduce your Solar Panel''s Voltage is by using either an MPPT Charge Controller or a Step-Down Converter (aka Buck Converter). Other solutions are to use resistors or modify the solar cells'' connections via the junction box.
