Abstract:
A solar generator panel includes at least one reflector for reflecting solar radiation onto at least one photovoltaic cell. The reflector takes the form of a flexible material blade, a first end of which is fixed to the panel and a second end of which remains free. The material has mechanical properties such that, in a first position, in the absence of vertical pressure, it maintains itself erect so that its free end points to outer space, thereby defining an upper face that faces outer space and an opposite lower face that faces the panel, and, in a second position, in response to vertical pressure, it orients its upper face toward the plane of the panel. One particular application is to high-power solar panels for satellites.
Abstract:
A solar generator panel comprising a plane array of strings of photovoltaic cells disposed side by side. According to the invention, the cells have cropped corners suitable for generating free spaces in the interstices between the cropped corners. It is then possible to place openings in those spaces for passing cables and/or for receiving damper blocks. The invention is particularly applicable to solar panels for satellites.
Abstract:
A spacecraft comprises a hybrid assembly equipped with at least one solar panel characterized in that said assembly comprises at least one solar cell provided with luminous energy concentration means and said assembly also comprises at least one solar cell with no luminous energy concentration means.

Abstract:
A (GS) for an equipment (EQ) including an electrical reference (ME) and including an area provided with at least two photoelectric cells (C) electrically connected and each covered by a protective window that can become electrostatically charged. This solar generator further includes, on the one hand, at at least one chosen place (EC) of the area, intensification means (MI) responsible for locally intensifying the electrostatic charge so as to force the generation of primary electrical arcs at that chosen place, and, on the other hand, discharging means (EL, LM) adapted to couple the intensification means (MI) to the electrical reference (ME) of the equipment (EQ) so as to evacuate to that electrical reference (ME) discharge currents induced by the primary electrical arcs.
Abstract:
A solar generator has at least two branches electrically connected in parallel at opposite first and second ends of positive and negative polarity, respectively, each branch comprising one or more photoelectric cells electrically connected in series and having a first end provided with first blocking means adapted to block an electrical current coming from an adjacent branch. The second end of each branch is provided with second blocking means adapted to limit the propagation toward an adjacent branch of a discharge current induced by an electrical arc in a photoelectric cell of its own branch to a value less than or equal to a nominal current value for that branch.

Abstract:
The solar panel for space satellites has a plane surface including a plurality of photovoltaic cells (CE) disposed side-by-side and substantially forming a grid, the cells (CE) being electrically connected into at least one serpentine (SE1), each serpentine made up of cells (CE) connected in series two-by-two forming parallel cell segments (SG), two successive segments (SG) of a serpentine being electrically connected at their ends, and each serpentine having positive terminals (+) and negative terminals (−), the positive (+) and negative (−) terminals being distributed along each serpentine (SE1) and over the surface of the panel so that the positive terminals are far away from the negative terminals, to reduce the risk of electrical arcing between two terminals. With this arrangement, the risk of electrical arcing is reduced without increasing the fabrication cost of the panel.
