- pvlib.pvsystem.dc_ohmic_losses(resistance, current)[source]#
Returns ohmic losses in units of power from the equivalent resistance of the wires and the operating current.
- Parameters:
resistance (numeric) – Equivalent resistance of wires. [ohm]
current (numeric, float or array-like) – Operating current. [A]
- Returns:
loss (numeric) – Power loss. [W]

Notes
Ohmic (also termed joule or heat) loss is the power lost due to current flowing through a conductor. Ohmic loss, \(L\), is computed as
\[L = I^2 \times R\]where \(I\) is the current (A) and \(R\) is the resistance of the conductor (ohms).
