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