PV Explorer

IV and PV curves for 16,000+ solar modules from their single-diode coefficients. Change the conditions, overlay a measured curve, and export.

Measured data Paste V/I pairs to overlay a field or flash-test curve

Tab or space separated voltage and current, up to 5,000 rows. The keypoint table gains a Measured column. For a full diagnosis with STC translation, use the IV Analyzer.

Degradation Model the curve after years in the field

First-year drop (%)

Annual rate (%/yr)

Start date

End date

Power retention = 100 % − first-year drop − annual rate × (years − 1). Set an end date after the start date to apply it to the curve.
