Solar panel power generation calculator, taking into account weather conditions

I created a widget for calculating the tilt and azimuth of a solar panel installation. The widget also calculates the solar panels' electricity generation, taking into account their efficiency. Selecting a region allows you to statistically calculate the number of sunny and cloudy days for the selected region and view an average annual electricity generation chart. The widget also includes a daily energy generation simulator, taking into account weather conditions and solar panel installation angles.
