You could always take the diode out of circuit all together and see what the results are.
I have done it many times over the years when using solar panels in parallel.
I just let the regulator do its work and deleted all the blocking diodes.
it may be a good experiment to see if any current actually goes back through the panel at night anyway.
Or you could make a small circuit with a LDR and a transistor to block current flow in reverse in low light conditions if there is actually any reverse current
