Report an error
Spotted a wrong number or an out-of-date rule? Tell us and we will fix it.
We want every result on SolarCalcLab to be right. If a calculator gives an answer you think is wrong, or a guide describes a rule that has changed, please tell us.
What helps us fix it fast
- The page address (URL).
- The inputs you entered and the result you saw.
- What you expected instead, and a source if you have one.
Send it through the form on our contact page with “Error report” in the subject. We review every report and update the page and its “last checked” date when we make a fix.
