Novelty: a solar tracker equipped with small-sized photovoltaic panels is disclosed. Constitution: boxes 1,2,3 having internal and external small-sized photovoltaic panels (1a,2a,3a) and ( 1γ,2γ,3γ) respectively, which panels follow up the trajectory of the sun and command the horizontal and vertical motion motors so that the biaxial sun tracker can be permanently and accurately turned in the vertical in respect to the position of the sun; the external small-sized photovoltaic panels are designed for the general surveillance of the horizon while the internal ones are meant to set, to a nicety, the sun tracker in the vertical position in respect to the sun position. The relays (1A, 1B, 2A, 2B, 3A, 3B) are separately connected to the small-sized photovoltaic panels which -when the sunlight fall thereon-transmit the electric current to the aforementioned relays which are liable to open, in turn, the electric circuit and oblige -each one separately- the sun tracker to execute a precise movement. |
