What is the temperature loss coefficient Pmpp of the DualSun module?

The coefficient of loss of Pmpp output due to temperature of the DualSun module is 0.467%/°C. All photovoltaic modules must measure their loss coefficient during standard IEC61215 photovoltaic tests: “10.4 Measurement of temperature coefficients.”

To learn more about the phenomenon of loss of efficiency and how DualSun panels combat this thanks to the DualBoost cooling effect, see: How does the cooling effect of the DualSun panel increase PV efficiency?
