Crimp connectors on single core wire?

[fubar.gr]

I want to put a crimp type ring terminal on a solid core 1.5mm2 electrical copper wire. Will this result in a reliable connection?

I've seen it done a bit, but I'm not a fan of the idea unless the terminal is soldered too.

As long as the crimp is suitably sized for the wire, either stranded or solid, it will work fine,

Soldering a crimp connector makes it far more brittle, which is even worse when your already dealing with single core wire,

There's a thread relevant to that question:

No way. Crimping solid wire is a big no. Extremely unreliable connection. Seen a them failing, caused me a big pain in the ass when I needed to go abroad and try to find such intermittent connections in the equipment made by idiots. If you extremely need to use crimp connector, then solder it afterwards.

I don't see how soldering will make it more brittle on a solid core wire. Stranded is another story of course, because you are turning part of the wire into solid core.

I'd say  don't do it unless you have parts and tools exactly specified for this application. Or at least test your crimps yourself, if the crimp holds more than 50% of the wire breaking strength its pretty good.
I have seen it only used on BIG cables and the crimping tools are not a joke.
According to undefined sources most? military standards also forbid crimped joints on single core.

You should also have much less capillary action so the solder should not run up the wire as much. This seems to agree with experience in tinning solid wire.
