At $1/watt, these Mono-crystalline $309 310 watt panels are excellent value.
Most importantly, they are PERC panels which hitherto have always carried a hefty price premium.
They are very efficient, providing 30 watts more than the 280 watt panels I recently bought that are exactly the same physical size. In addition, in low light conditions, PERC panels produce more power than standard panels.

1650mm x 992mm x 35mm
Weight: 18.6kg

These panels have a 25 year 80% Output Guarantee and 10 year Manufacturing Guarantee.

Very nice!

And even better:
Pallets from $245+ per panel.
Now if only that 40v VoC wasn’t so much more than my existing ones and making me buy another controller to run them :roll:

They are good value Neville :TU Unfortunately the physical size of these panels prevented me from fitting them to our new caravan. However, all was not lost as Ben (Gadget) still had some 200 watt panels left over from the 15 panel private bulk import he did back in 2017. (All gone now) These also worked out right on $1 / watt, all be it not the higher efficiency "PERC" panels.

Would I be correct in assuming there would be no problem in adding a PERC panel to my existing non-PERC panels (provided of course I keep within the Amp-input capability of my controller) - after all, an Amp is an Amp, regardless of what type of panel it is produced by?

No problems there, John. As you say, an Amp is an Amp, regardless of the panel type.
If the new panel has a similar voltage to the existing panel(s) if can be wired in parallel with them.
If its current is similar to existing panel(s) current, it can be wired in series with them.
A totally different panel would be best served by having its own separate controller.
