A faulty inverter or charge controller are the most likely reasons for a solar panel to register no voltage. Other possible reasons for low to zero power are a damaged PV module, poor wiring, shading and temperature higher than the ideal operating range.

The voltage at which the panel produces maximum power, typically ranging from 18V to 36V. A classification system (12V, 24V, 48V) used for compatibility with batteries and.
Battery Floating Charging Voltage - This voltage keeps the battery at full charge and stops it from losing power on its own. For a 12V system, this is usually 13.
This is a DC power meter (aka watt meter): You can find them for cheap on Amazon. Connect one inline between your solar panel and charge controller and it'll measure voltage, current, wattage, and more.
This means your solar panel is generating voltage (open circuit), but the circuit is incomplete and therefore cannot generate current. This could be due to a loose or broken wire, a faulty inverter or charge controller, a poor connection, or an internal problem with the panel.
A 3V solar panel refers to a photovoltaic device designed to convert sunlight into electrical energy with a nominal output voltage of approximately 3 volts.
Typically, a 100-watt solar panel produces about 5.55Amps/18 voltsof maximum power voltage. The voltage that solar panels produce when they produce electricity varies according to the number of cell.
Solar panels, unless heavily shaded have a remarkably high and consistent voltage output even as the intensity of the sun changes. Panel temperature will affect voltage - as has been discussed.
