| Popis: | The efficiency of the energy conversion in photovoltaic panels varies according to the angle of light incidence. A new method of iterative repositioning of the panels at maximum-efficiency direction has been proposed. This method frees up the use of sun position sensors and uses the instantaneous power delivered to the power line by each panel, among a series of photovoltaic panels, as a feedback in determination of the best position in a closed-loop operation. The proposed repositioning method, as well as the repositioning dynamic of a series of photovoltaic panels, has been modeled. The system has been simulated in a single parallel-rays light source scenario. In simulations, the convergence of panels to the best energy conversion position was observed. |
