Information

Model of a simple photovoltaic array.

The electrical connector is an AC interface.

This model computes the active power as

P=A   fact   η   G   ηDCAC,

where A is the panel area, fact is the fraction of the aperture area, η is the panel efficiency, G is the total solar irradiation, which is the sum of direct and diffuse irradiation, and ηDCAC is the efficiency of the conversion between DC and AC.

This active power is equal to P, while the reactive power is equal to Q = P   tan(acos(pf)) where pf is the power factor.

Note: This model takes as input the total solar irradiation on the panel. This has to be computed converting the incoming radiation to take tilt and azimuth into account. For a model that implements this conversion, use Buildings.Electrical.AC.OnePhase.Sources.PVSimpleOriented.

Revisions

  • March 23, 2022, by Michael Wetter:
    Corrected documentation string for parameter A.
  • October 7, 2019, by Michael Wetter:
    Corrected model to include DC/AC conversion in output P.
    This is for issue 1577.
  • January 30, 2019, by Michael Wetter:
    Added replaceable.
  • February 26, 2016, by Michael Wetter:
    In load, set P_nominal = 0 as it is not used. This is for issue 426.
  • September 24, 2015 by Michael Wetter:
    Removed binding of P_nominal as this parameter is disabled and assigned a value in the initial equation section. This is for issue 426.
  • September 4, 2014, by Michael Wetter:
    Revised model.
  • August 5, 2014, by Marco Bonvini:
    Revised documentation.
