Inverter Clipping & Ghost Energy Recovery
String-level variance analysis across 31 days of 5-minute inverter data, quantifying the ghost energy lost when DC input exceeds AC inverter capacity.

Ideal Deployment Profile
Reference study summary
Site dashboards show inverters staying within rated AC limits, so the site appears healthy while usable generation is still being discarded every day.
DC-to-AC string-level analysis reveals systematic clipping during peak irradiance, with up to four hours per day of lost generation.
Operators receive a forensic yield report quantifying the kWh loss per string, which supports inverter resizing or curtailment changes worth more than $300K per year at 100MW scale.
Methods used in this study
String-level irradiance normalization

What made this dataset hard
to review well
Inverters report "healthy" while silently discarding generated power
Standard monitoring shows AC output only, so the DC / AC clipping gap is missed
String-level underperformance hidden by fleet-average reporting
How the review
