Simple PV model

Extends from Buildings.Electrical.Interfaces.PartialPV.

Information

Model of a simple photovoltaic array.

This model computes the power as

P=A   fact   η   G

where A is the panel area, fact is the fraction of the aperture area, η is the panel efficiency and G is the total solar irradiation. This power is equal to P = v   i, where v is the voltage across the panel and i is the current that flows through the panel.

To avoid a large voltage drop the panel electric connector, it is recommended to use this model together with a model that prescribes the voltage. See Buildings.Electrical.DC.Sources.Examples.PVSimple.

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.

Revisions

  • March 23, 2022, by Michael Wetter:
    Corrected documentation string for parameter A.
  • 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.
  • January 4, 2013, by Michael Wetter:
    First implementation.
