Doesn’t seem hard. Just hook up the voltmeter ground to ground. the other end to the switch, then just hook up the outputs of the switch to the solar panel and the battery Vdd.

For starters, you need a double pole, 3 position switch.
In Position "1" – pole 1 connects the solar cell to the battery. Probably with a diode or whatever, for night time when the battery voltage exceeds solar cell voltage. Pole 2 is not connected.
In Position "2" – pole 1 disconnects the solar cell. Pole 2 connects the cell to the meter.
In Position "3" – pole 1 disconnects the solar cell. Pole 2 connects the Battery to the meter.
Hope that helps …
