max_power_point
(photocurrent, saturation_current, resistance_series, resistance_shunt, nNsVth, method='brentq')[source]¶ Given the single diode equation coefficients, calculates the maximum power point (MPP).
- Parameters
photocurrent (numeric) – photo-generated current [A]
saturation_current (numeric) – diode reverse saturation current [A]
resistance_series (numeric) – series resitance [ohms]
resistance_shunt (numeric) – shunt resitance [ohms]
nNsVth (numeric) – product of thermal voltage
Vth
[V], diode ideality factorn
, and number of serices cellsNs
method (str) – either
'newton'
or'brentq'
- Returns
OrderedDict or pandas.Datafrane –
(i_mp, v_mp, p_mp)
Notes
Use this function when you only want to find the maximum power point. Use
singlediode()
when you need to find additional points on the IV curve. This function uses Brent’s method by default because it is guaranteed to converge.
