sunpeek.components.types.calculate_eta0b(eta0hem, kd)

Calculate beam peak collector efficiency eta_0b from hemispheric peak eta0hem and diffuse IAM kd.

Parameters:

• eta0hem (hemispherical peak collector efficiency based on SST test)

• kd (diffuse incidence angle modifier)

Notes

This method is based on the SST-QDT conversion formulas in ISO 9806 Annex B.

Return type:

Tuple[Quantity, str]

Returns:

• eta0hem (pint.Quantity, The calculated hemispherical peak collector efficiency)

• info (string, information on calculation method used)
