How can I upload my own private meteorological data?

You can do so in the “Location” tab, in “Meteo data”. You can use our generic templates and fill in the corresponding columns with the required data. After that, make sure to save the file as a CSV and then upload it to RatedPower by selecting one of the "generic" options found in the TMY file drop-down list above. For more information on this, you can check this article.
