The claims for 20 to 43% increase efficiency are bogus which makes all the other claims suspect.
We have a high voltage panel that typically puts out 43V at the controller in full sun with no tilt. It is run through a Morningstar Sun Saver MPPT controller and I monitor using a Victron battery monitor. The high voltage means you get some usable current even in shaded areas. Just for fun I measured voltage from a full moon and got 12.7V.

The reason I didn't go even cheaper is many of those are labeled as MPPT but a look at the guts proves it isn't so. ( at least at that time) A look in the Eco-worthy shows the MPPT coil as well as the temp sensor that I can confirm at least works.
