Heat 1, MPPT 0
Previously we noted that heat is hard on MPPT due to the panel's loss of voltage with increasing heat. Doesn't bother PWM though, you still get Isc or more. This Spring, I took some measurements p...

Both Spring and Now results in the OP were with voltage at 13v. To get the max amps possible showing, I had lots of load running to over 30amps so the SOC of the batts didn't matter. The Trimetric and the Eco-W amps readings agreed with each other for confirmation.
The sky was blue both times but can't say what actual insolation and air mass was of course. If the blue had haze I can't see this time, the sun being higher should counter that. However it is a weakness in the test that I can't compare actual insolations. I ASSume that since the Isc of the panel was over its rating each time that insolation was sufficient to get max amps.
Somebody was going to do a side-by-side comparison of an Eco-Worthy with a MorningStar but he wimped out on us :)
