Thanks for the quick heads up. To make it clear, I'm not looking for the math theory behind it, I'm trying to find an existing Python library or source code that I can integrate or use for writing the service. I want to track the energy production, we have a fixed setup. I'm not interested in sun tracking calculation now.
