pvdeg.design.edge_seal_width

pvdeg.design.edge_seal_width(weather_df: DataFrame, meta: dict, k: float = None, years: int = 25, from_dew_point: bool = False)

Determine width of edge seal required for given number of years water ingress.

Parameters:

• weather_df (pd.DataFrame) – must be datetime indexed and contain at least temp_air, dew_point

• meta (dict) – location meta-data (from weather file)

• k (float) – Ingress rate of water through edge seal. [cm/h^0.5] Specifically it is the ratio of the breakthrough distance X/t^0.5. See the function design.edge_seal_ingress_rate()

• years (integer, default = 25) – Integer number of years under water ingress

• from_dew_point (boolean, optional) – If true, will compute the edge seal width from dew_point instead of dry bulb air temp.

Returns:

width (float) – Width of edge seal required for input number of years water ingress. [cm]
