I'm not sure if I'm correct but I think you created your environment variable SOLARPI_SECRET in your local machine's environment but you are running your application through virtual environment venv you created so what this would do is it would search your environment variable SOLARPI_SECRET in your virtual environment but as your environment variable SOLARPI_SECRET is actually present in your local machine's environment it gives you error namely KeyError as it is unable to find SOLARPI_SECRET in your virtual environment variable.

Refer this article to get a better insight of using virtual environment variables.
