You need to redo it with a continuous wire, unless you are equipped to
weld (not solder) the wires together. This is generally only done on big
commercial work and is done with exothermic welding gear which you in
all probability don't have.
Assuming this is a residential scenario, the service panel does not
contain high voltage, it contains 240V. Even if it's commercial it isn't
likely above 480V which is still not high voltage.
If you really don't feel safe working in the panel, install your ground
rods and the wire all the way back to the panel leaving plenty of extra
and then have an electrician stop by and make the connection in the
panel.
