Production assessment · 90 days
System performance record
72%
actual ÷ modeled expected
This sample result is below the modeled range.
Recorded production was 72% of the weather-adjusted model. The uncertainty range remains below the expected range, so a qualified service review may be useful. Production data alone cannot identify the cause.

What this result cannot see
The expected value is modeled, not measured. Tree growth and other shading changes can reduce production and are not visible to this method. Soiling and inverter clipping also add uncertainty. This report does not identify a hardware fault or its cause.
Sample comparison window: May 1–July 29, 2026, America/New_York. Irradiance source: demonstration fixture, not a live historical-weather feed. Model: weather-ratio-v0.1.0.
Optional next step
Ask a service contractor to review the record.
We may be paid by a contractor if you choose a referral and later hire them. Payment never changes this assessment. No contractor receives your information unless you consent to this specific referral.
The referral would include your production history, system specifications, equipment, service address, and what you have already tried.
