In this article, an artificial algorithm called hummingbirds optimization method, named AHA algorithm, is settled to extract accurately the parameters of PV modules under outdoor operational conditions. AHA is the main contribution in this work, regarding its efficiency and good performance in terms of standard deviation (StD), root mean square error (RMSE), sum of squared error (SSE), maximum number of iterations (MaxIt), particularly, for extracting parameter from modules operating in real conditions, and under different temperature and irradiance levels. The AHA is applied on a Polycrystalline-solar panel module type 320W-72P at real operating conditions and on a PV array of three polycrystalline PV modules connected in series. PV cells of the same modules are assumed operating under the same conditions where they share the same electric current and voltage values. In this last pattern, eight different scenarios are chosen. In the first five scenarios, the temperatures are (46.97, 44.23, 42.87, 40.59 and 30.60&#x00B0;C), and the irradiance varies, such as (910, 800.57, 614.13, 415.1 and 200.87W/m2), respectively. In the other three testing scenarios, the solar irradiance is equal (803 W/ m2), and the temperature differs, such as <inline-formula> <tex-math notation="LaTeX">$\text{T}= 47.93\,\,^{\circ }\text{C}$ </tex-math></inline-formula>, 53.38 &#x00B0;C and 36.62&#x00B0;C. Lower values of root mean square errors (RMSE) are achieved (<inline-formula> <tex-math notation="LaTeX">$9.8602\times {10}^{-4}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$2.572533\times {10}^{-2}$ </tex-math></inline-formula> for RTC France PV cell and the 320W-72P module respectively) with 6000 iterations. Moreover, all the eight scenarios are lower than <inline-formula> <tex-math notation="LaTeX">$7.245916\times {10}^{-2}$ </tex-math></inline-formula> for the last case study. Moreover, results show that we could recommend the AHA algorithm as an advanced and efficient method for dealing with real time parameter optimization of photovoltaic modules. In fact, a high closeness between the simulated and the experimental curves is achieved, which indicates the perfectness of this optimization method. Finally, the proposed AHA algorithm can be engaged as tools for the best designing of PV systems.
