  • Patent number: 10978878
    Abstract: A solar cell management system for increasing the efficiency and power output of a solar cell and methods for making and using the same. The management system provides an electric field across an individual solar cell, an array of solar cells configured as a panel, or a group of solar panels. The imposed electric field exerts a force on both the electrons and holes created by light incident on the solar cell and accelerates the electron-hole pairs towards the electrodes of the solar cell. Compared to conventional solar cells, these accelerated electron-hole pairs travel a shorter distance from creation (by incident optical radiation) and spend less time within the solar cell material, therefore the electron-hole pairs have a lower likelihood of recombining within the cells' semiconductor's material. This reduction in the electron-hole recombination rate results in an overall increase in the solar cells' efficiency and greater power output.

The cells can have different shapes, sizes, and orientations, enabling the array to be flexible in any desired direction. Higher efficiencies and lower hot spotting under shading is achieved by connecting small low current, high voltage cells in dense series and parallel configurations.

  • Patent number: 10868493
    Abstract: The present disclosure provides a technique capable of improving an SN ratio of a current signal which is superimposed on a power line in a photovoltaic string and transmitted and efficiently specifying a failure location. A current source 151 is connected to a power line 11 in parallel with each of photovoltaic elements 14. A controller 152 controls a current value of the current source 151 such that a current signal is generated. A bypass capacitor 153 is connected to the power line 11 to be parallel to the each of the photovoltaic elements 14 and the current source 151. Accordingly, the bypass capacitor 153 can transmit a current signal transmitted through the bypass capacitor 153 from a negative electrode side in a photovoltaic string to a positive electrode side.

  • Patent number: 10855220
    Abstract: Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, particularly as multi-region roofing modules that have photovoltaic elements embedded or incorporated into the body of the module, in distinct tiles-sized regions. Such multi-region photovoltaic modules can replicate the look of individual roofing tiles or shingles. Further, multi-region photovoltaic modules can include hinged support structures along the upper edge of the modules, allowing for lifting of portions of an installed module, giving access to the underlying roof deck for more efficient installation, maintenance, or removal of roofing structures down-roof of the installed module.

  • Patent number: 10822801
    Abstract: A non-slip roof attachment system for attaching structures to residential and commercial roofs without the use of penetrations to roofing shingles and sealing layers is described. The non-slip attachment system may be used to attach roof mounted systems such as solar panels. The non-slip attachment system also allows for the quick removal of such roof mounted systems rapidly and without the need for repair of penetrations. The non-slip attachment system uses, among other things, an array-stay retainer comprising a vertical member and a horizontal member. A high friction foam polymer padding is used to further secure the non-slip attachment system to the roof.

  • Patent number: 10809345
    Abstract: A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.
