1 voltage meter for both solar panel and battery

Well in that case you just need a change over switch. Connect the yellow wire to the common and the battery +ve to one of the other contacts and the solar to the other contact. See thishttps://learn.sparkfun.com/tutorials...pen-and-closed you can get a small switch for Maplin ..Clive

Ok, thanks for your help. So i need a SPDT and switch the common, is that correct

Yes in this case the common goes to the meter (yellow wire) but the red wire will have to be energised from the battery because the solar panel may not be providing enough Voltage to drive the meter. The -ve on the solar panel will have to be connected to the battery -ve hope this helps you could of course put 2 meters on the system ..Clive
