A concentrator photovoltaic solar cell array system includes a central support mountable on a surface and a solar cell array including triple junction III-V semiconductor compound solar cell receivers and a support frame coupled to the solar cell array and carried by, and rotatable with respect to, the central support about an axis orthogonal to the central longitudinal axis. The support frame can include (i) a first frame assembly coupled to the solar cell array and (ii) a second frame assembly coupled to the first frame assembly arranged to increase the rigidity thereof. The system also has an actuator for rotating the central support and the support frame as well as pivoting the support frame so as to adjust its angle with respect to the earth's surface, so that the solar cell array is maintained substantially orthogonal to the rays from the sun as the sun traverses the sky.
摘要:
A solar cell receiver for use in a concentrating solar system which concentrates the solar energy onto a solar cell for converting solar energy to electricity. The solar cell receiver may include a solar cell mounted on a support and with one or more III-V compound semiconductor layers. An optical element may be positioned over the solar cell and have an optical channel with an inlet that faces away from the solar cell and an outlet that faces towards the solar cell. A frame may be positioned over the support and extend around the solar cell with the frame having an inner side that extends above the support and faces towards the optical element. An encapsulant may be positioned over the support and contained between the optical element and the frame. The encapsulant may have enlarged heights at contact points with the optical element and the frame and a reduced height between the contact points away from the optical element and the frame. The solar cell receiver may be used in a solar cell module.

Terrestrial solar tracking photovoltaic arrays that may include a modular design that is sized and weighted to facilitate installation with a small amount of manpower. The array may further be adapted to be adjusted during or after installation to accommodate the necessary power requirements. The terrestrial solar tracking photovoltaic array may include a torque tube that may be constructed of discrete sections. A drive may be connected to the torque tube to rotate the torque tube. A number of solar cell modules may be connected to the torque tube. The modules may be positioned at offsetting angular orientations depending upon their distance away from the drive. This offset positioning compensates for twisting distortion of the torque tube caused by the drive rotating the torque tube. At one point of rotation, each of the solar cell modules may be substantially aligned in a common plane.

The present application is directed to methods of forming an integral lens sheet for use with a photovoltaic solar cell subassembly. The integral lens sheet is constructed from a parquet member and one or more individual lenses. One embodiment of a method may include positioning an individual lens over each of the apertures in the parquet member. The size of the lenses may provide for peripheral sections of the lenses to overlap the parquet member. Each of the lenses may be welded to the parquet member by directing a laser beam through the peripheral sections and onto the parquet member. The laser beam may form a laser weld between the parquet member and an underside of the individual lenses.

A terrestrial solar tracking photovoltaic array with a longitudinal support that may be constructed of discrete sections. The overall length of the array may be adjusted depending upon the necessary size of the array. A drive may be configured to rotate the longitudinal support about a first axis. The drive may include a slew speed reducer. Solar cell modules are positioned along the longitudinal support and may each include a rectangular case with a plurality of lenses that are positioned over corresponding receivers. Linkages may be connected to frames and are axially movable along the longitudinal support to rotate the solar cell modules within second planes that are each orthogonal to the first plane to further track the sun during the course of the day.

A terrestrial concentrator solar tracking photovoltaic array that may include an elongated frame configured to mount concentrator solar cell modules in a longitudinally-extending and spaced-apart arrangement. The frame is able to rotate each of the concentrator solar cell modules along a first axis to simultaneously track the elevation of the sun during the course of a day. The frame is also able to rotate each concentrator solar cell array module along second axes that are substantially perpendicular to the first axis to track the azimuthal position of the sun during the course of the day.

Solar cell modules for converting solar energy into electrical energy. The modules includes a housing formed from three separate members that are attached together to form an interior space. A top member extends across an open side of the housing and includes one or more lenses. One or more solar cell receivers are positioned within the interior space of the house and are aligned with one or more of the lenses to receive and convert the solar energy into electrical energy.
