- pvlib.ivtools.sdm.fit_desoto_batzelis(v_mp, i_mp, v_oc, i_sc, alpha_sc, beta_voc)[source]#
Determine De Soto single-diode model parameters from datasheet values using Batzelis’s method.
This method is described in Section II.C of [1] and fully documented in [2].
- Parameters:
v_mp (float) – Maximum power point voltage at STC. [V]
i_mp (float) – Maximum power point current at STC. [A]
v_oc (float) – Open-circuit voltage at STC. [V]
i_sc (float) – Short-circuit current at STC. [A]
alpha_sc (float) – Short-circuit current temperature coefficient at STC. [A/K]
beta_voc (float) – Open-circuit voltage temperature coefficient at STC. [V/K]
- Returns:
dict – The returned dict contains the keys:
alpha_sc[A/K]a_ref[V]I_L_ref[A]I_o_ref[A]R_sh_ref[Ohm]R_s[Ohm]
