Solar device for energy efficiency increasing of photovoltaic and photothermic systems

摘要

Solar device for energy efficiency increasing of photovoltaic and photothermic systems is characterized in that mirror surfaces (1) having against active areas (2) of solar panels (3) mounted on a fixed supporting structure (15) an adjustable pitch angle. An upper edge (4) of a reflected area (5) of solar radiation from the mirror surface (1) coincides with the upper edge (6) of the active areas (2) of the solar panels (3), the mirror surfaces (1) are tilting about a horizontal axis to a rotary hinge (9) mounted on the support fixed parts (7) and the mirror parts (8) bearing on the opposite side the mirror surfaces (1). A tilting mechanism (10) is mounted on the support fixed part (7) and on the mirror part (8) and is connected with a controller (11), which has in a feedback circuit connected at least two differential solar sensors (12, 13).
