Enter your array and inverter capacity to get the DC/AC ratio and an indicative clipping loss, screened against a reference curve.
A DC/AC ratio above 1.0 is often intentional, modules rarely produce at their full rated output, so modest oversizing can increase total annual energy even with some clipping. The right ratio depends on your site's irradiance profile and project economics.
Indicative only. Actual clipping loss depends on site-specific irradiance profile, tilt, orientation, and inverter clipping behaviour, and requires full hourly simulation (e.g. PVSyst, SAM) to determine precisely. Use this as a first-pass screening check, not a design input.
