SUNIVA 270 VS the Solar World 275

SolarPowered

As a reminder the solar worlds are 2 months old, and I cleaned them 2 weeks ago.
The 2 locations are less than 19miles apart from each other, the daily graph shows roughly the same percentage in MPPT clipping, so what do you think is better? The suniva 270, or the solar world 275? I believe the suniva's have less internal resistance than the solar worlds under PTC conditions. Suniva's are on the left, solar world's are on the right.
