Irradiance Sensor Calibration Record Not Approved Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the irradiance sensor calibration record, solar met sensor calibration signoff, or irradiance-device approval still lacks approval. This page fits projects where the missing deliverable is the calibration record for the irradiance measurement equipment used for performance reporting, not the panel or inverter hardware itself. The commercial problem is that the PV plant may already be operating, yet the final payment is still being held until the calibration record is accepted. Your email should ask whether the irradiance calibration record is the only remaining blocker, whether the latest certificate has already been issued, what device, date, or traceability detail remains unresolved, and whether payment will be released once the record is approved. The aim is to narrow the delay to one exact measurement-quality document instead of open-ended remarks about incomplete performance verification.
