Abstract

A system for producing electricity with solar panels includes solar panel systems arranged in a grid formation, wherein each solar panel system includes a solar cell assembly consisting of solar panels configured to be movable on a support structure. A connection of each solar cell assembly includes rotation means and tilting means. The system includes control means by means of which, at a selected moment in time, when an incoming angle of the sun's rays is greater than a selected minimum value, but less than a selected limit value, the solar cell assemblies are configured to be rotated so that an angle of rotation of the solar cell assemblies relative to the direction of incoming sunlight is 20°-50°, and tilted to reduce a three-dimensional solar incidence angle of the solar cell assemblies so that the solar cell assemblies do not overshadow one another.

Dependent claims

A system for producing electricity with solar panels north of the latitude 55°N or south of the latitude 55° S, which system comprises a plurality of individual solar panel systems arranged in a grid formation so as to form a solar panel field, wherein each individual solar panel system comprises a solar cell assembly made up of solar panels that is configured to be movable on a support structure with respect to two axes, so that a connection of each individual solar cell assembly to the support structure comprises rotation means for rotating the solar cell assembly relative to a vertical axis of the support structure and tilting means for tilting the solar cell assembly relative to a horizontal plane, and wherein, when an incoming angle of the sun's rays in the grid formation is less than 20° and when the solar cell assemblies are perpendicular to the sun, the solar cell assemblies overshadow one another, wherein in the system a width of the solar cell assembly of each solar panel system is 3-6 times, preferably 3.5-5 times, a height of the solar cell assembly, wherein

the system comprises control means by means of which, at a selected moment in time, when an incoming angle of the sun's rays is greater than a selected minimum value, preferably greater than 1°, but less than a selected limit value, preferably less than 20°, more preferably less than 10°, most preferably less than 5°, the solar cell assemblies are configured to be rotated by the rotation means so that an angle of rotation of the solar cell assemblies relative to the direction of incoming sunlight is 20°-50°, preferably 30°-45°, and
tilted by the tilting means in order to reduce a three-dimensional solar incidence angle of the solar cell assemblies in such a manner that the solar cell assemblies do not overshadow one another,
by means of which rotation and tilting of the solar cell assemblies an inter-shading that would otherwise occur is prevented and an electricity output is maximized.

A method for producing electricity with solar panels north of the latitude 55°N or south of the latitude 55°S, in which method a plurality of solar panel systems are placed in a grid formation so as to form a solar panel field, wherein each individual solar panel system comprises a solar cell assembly made up solar panels arranged on a support structure, with respect to which support structure the solar cell assembly is moved during the day with respect to two axes in such a manner that the solar cell assembly is rotated relative to a vertical axis of the support structure and tilted relative to a horizontal plane, and wherein, when an incoming angle of the sun's rays in the grid formation is less than 20° and when the solar cell assemblies are perpendicular to the sun, the solar cell assemblies overshadow one another, and in which method a width of the solar cell assembly of each solar panel system is 3-6 times, preferably 3.5-5 times, a height of the solar cell assembly, wherein,

at a selected moment in time, when an incoming angle of the sun's rays is greater than a selected minimum value, preferably greater than 1°, but less than a selected limit value, preferably less than 20°, more preferably less than 10°, most preferably less than 5°,
the solar cell assemblies are rotated so that an angle of rotation of the solar cell assemblies relative to the direction of incoming sunlight is 20°-50°, preferably 30°-45°, and
the solar cell assemblies are tilted in order to reduce a three-dimensional solar incidence angle of the solar cell assemblies in such a manner that the solar cell assemblies do not overshadow one another,
by means of which rotation and tilting of the solar cell assemblies an inter-shading that would otherwise occur is prevented and an electricity output is maximized.
