.Buildings.Electrical.AC.OnePhase.Sources.PVSimple

Information

Model of a simple photovoltaic array.

The electrical connector is an AC interface.

This model computes the active power as

P=A   f_act   η   G   η_DCAC,

where A is the panel area, f_act 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 η_DCAC 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.
