Inverter clipping, or “inverter saturation,” occurs when DC power from a PV array exceeds an inverter’s maximum input rating. The inverter may adjust the DC voltage to reduce input power, increasing voltage and reducing DC current. Alternatively, the inverter may restrict or throttle the inverter’s AC output.
It is commonly assumed that cleaning photovoltaic (PV) modules is unnecessary when the inverter is undersized because clipping will suficiently mask the soiling losses. Clipping occurs when the inverter’s AC size is smaller than the overall modules’ DC capacity and leads to the conversion of only part of the PV-generated DC energy into AC.
The inverter may adjust the DC voltage to reduce input power, increasing voltage and reducing DC current. Alternatively, the inverter may restrict or throttle the inverter’s AC output. Inverter clipping is typically seen in PV systems that have high — for example, greater than 1.4:1 — DC/AC ratios. Why does it matter?
Overall, some clipping is nothing to worry about. Many solar arrays experience some clipping on a few sunniest days of the year. However, if you see clipping happening regularly outside of these peak sun days, you may want to talk with your solar provider about increasing the size of your inverter.
