Note: All results are annual values unless otherwise specified.
Important: Only regenerate weather.npz if you update the weather data (DNI, GHI, Temperature sheets) in Excel.
You do not need to regenerate weather.npz when changing simulation input parameters.
Note: Small differences from Excel results (typically less than 1%) are expected due to floating-point math and calculation order. These are not errors and do not affect engineering accuracy.
