The best photovoltaic solar panels

The OP has suggested some panels but we have no link to availability or cost.
Yes MPPT is part of the cost.

In this case I am not talking about the cost of the MPPT but how good it is at making amps from a particular panel. I don't know if it is better to have the same watts with more of the watts in volts than in amps or to have lower volts and more amps in the watts make-up, for an MPPT to do better.

I also don't know if all MPPTs are the same in that regard or if they are, if they are equal at making amps from the same combo of volts times amps

So, while I do know those so called 145w DM panels are low in amps more like a 130w "normal" panel, so it is easy to say they are poor at making amps for their wattage rating (so I would not ever buy one--waste of money--unless they were lower in cost than a normal 130w panel) --

-- I have no idea how to view different 24v panels wrt their amps portion of their watts, since they need an MPPT to make the real amount of amps they do in combo.

Does anybody know how to evaluate "24v" panels for their amps-making abilities? If one gets more Isc for the same watts does that mean with an MPPT it will make more amps to the battery--where supposedly the MPPT is making extra amps out of the voltage (so the amps don't matter, it is more volts you want?)

I get the idea that the MPPY does not make "extra" amps on top of the panel's Isc with 24s. It does with 12s though. with 24s I wonder if it makes all the amps and the Isc or Imp part is not "part" of it at all, that the MPPT makes all the amps from scratch, so Imp means nothing. ????
