Cold Temperature Voc Calculator

Apply a signed module voltage coefficient to a colder module temperature.

Starting values are editable examples. Enter your own loads, datasheet values and site assumptions.

Solar & Battery

A module's open circuit voltage can increase as its temperature drops. The datasheet coefficient provides the calculation basis.

Enter the signed Voc coefficient and a suitable cold module temperature. Compare the corrected voltage with the reference condition.

01 / GET STARTED

How to use Cold Temperature Voc Calculator

  1. Enter reference open circuit voltage, voc temperature coefficient and reference cell temperature.
  2. Enter minimum module temperature and panels in series.
  3. Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
02 / A CLEARER WORKFLOW

Why choose this tool?

Showing the coefficient and temperature makes the correction traceable during a string voltage review.

Before you use the result

Uses a linear coefficient from the datasheet and an entered module temperature. A site minimum and equipment margin require design review. This does not select a permitted string length.

03 / COMMON QUESTIONS

Questions about Cold Temperature Voc Calculator

Does this select the permitted series count?

No. Equipment voltage limits, site minimum temperatures and design margins need a separate string check.

What should I check before using Cold Temperature Voc Calculator?

Check Reference open circuit voltage, Voc temperature coefficient, Reference cell temperature and Minimum module temperature. Use the exact units shown beside the controls and replace any example values with your own inputs.
