All connections made with wire should be done with some kind of mechanical connection, like a Twist-on wire connector, busbar, terminal or PV module connector. Connections performed solely with electrical tape - as is common practice in many parts of the world - are far more likely to fail and cause issues.
All wires that are entering a connection (busbar, should leave some conductor (copper) exposed to ensure that insulation is not entering the connection. Insulation in a connection can create resistance, heat and ultimately a fire.
All connections should be tested with a gentle tug after being completed to ensure that the connection is solid and will not come undone easily.
