What is the Module Temperature Coefficient of Power (PKpmp)?
In order to determine how much the panel’s overall output power is affected by changes in temperature, we need to know the Temperature Coefficient of Power. Like the Coefficients of Voltage and Current, the magnitude of the Coefficient of Power represents how much, or how little, changes in temperature will affect the performance of the panels. As you will notice, the Coefficient of Voltage is usually much larger, 10 to 100 times larger typically, than the Coefficient of Current. This means that the Coefficient of Power is influenced more by the Coefficient of Voltage than the Coefficient of Current. The maximum input power is actually a fuzzy limit. This means that if you were to exceed this value with a given number of panels, you might not actually damage the inverter, as you would with too much voltage or current, but you may see decreased performance. For more information about why the limit is fuzzy, please see this discussion about the different ways to rate panels. For more inf
