Information

Model of a simple photovoltaic array.

This model computes the power as

P=A   f_act   η   G

where A is the panel area, f_act is the fraction of the aperture area, η is the panel efficiency and G is the total solar irradiation, which is the sum of direct and diffuse irradiation. The model takes into account the location and the orientation of the PV panel, specified by the surface tilt, latitude and azimuth.

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.PVSimpleOriented.

This model takes as an input the direct and diffuse solar radiation from the weather data bus.

Revisions

• March 23, 2022, by Michael Wetter:
  Corrected documentation string for parameter A.
• September 16, 2021, by Michael Wetter:
  Removed parameter lat as this is now obtained from the weather data reader.
  This is for IBPSA, #1477.
