So, is it basically something like overpaneling in PV systems, where the total amount of energy which could theoretic be harvested through the panels (surface area times efficiency) is higher than the maximum possible energy throughout of the inverter? This leads to a steady energy throughout which is capped by the inverter, providing a “buffer” for shaded conditions, morning, evening, etc.
They are really well designed too. They lock into place when flipped 180 degrees (drinking mode) and don’t interfere at all while drinking.
