Clipping
When a solar inverter limits output because the DC input power from the panels exceeds the inverter's AC output rating. The excess energy is lost.
Why It Matters
Solar systems are often designed with a DC/AC ratio above 1.0 (e.g., 1.2 or 1.3), meaning panels can produce more DC than the inverter converts. Clipping occurs during peak hours but increases total energy harvest overall.
Real-World Example
Related Terms
Inverter
A device that converts direct current (DC) electricity from solar panels into alternating current (AC) electricity used by your home.
String Inverter
A central inverter that connects to multiple solar panels in series (strings). Less expensive than microinverters but less flexible.
DC/AC Ratio
The ratio of a solar array's DC panel capacity to the inverter's AC output rating. Typical residential values range from 1.1 to 1.35.
