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.
Why It Matters
Higher ratios (more panels per inverter) reduce hardware costs and increase morning/evening production, with some midday clipping. A well-designed ratio maximizes lifetime energy value.
Related Terms
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.
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.
