Abstract: A photovoltaic system has at least two bifacial solar modules, which are respectively held in a module holder, and a reflector. The module holders are configured to hold two bifacial solar modules vertically positioned and parallel to each other, wherein the module holders are interconnected via the reflector.

Abstract: A frame profile (1) for a solar cell laminate (10) includes a laminate clamping section (2), which comprises two parallel clamping feet (2a, 2b) configured plane and mutually spaced apart for clamped mounting of the solar cell laminate (10); and a profile section (3) adjoining the laminate clamping section (2), which includes a portion formed—by sides (3a, 3b)—for the solar cell laminate (10). Therefore, the sides (3a, 3b) are formed such that the portion includes an undercut at least partially. A solar module (100) with at least one such frame profile (1) has a panel-shaped solar cell laminate (10), which is inserted between the clamping feet (2a, 2b) of the laminate clamping section (2) right up to the portion and is connected to the frame profile (1) of an at least partially framed solar module (100).

Abstract: A photovoltaic apparatus may have a solar panel with at least one bifacial solar cell. The apparatus may include a solar panel, a support structure, a mounting member, and at least one reflector. A first location of the support structure may be configured to rotatably attach to the solar panel. A first location of the mounting membermounting member may be configured to rotatably attach to a first location of the support structure. At least one reflector may be configured to attach to a second location of the mounting member. The reflector(s) may reflect light onto a first side and/or a second side of the solar panel, and the reflector(s) may be fixed relative to the solar panel; the reflector(s) and the solar panel may be configured to rotate together about an axis.

Abstract: The present invention relates to a method for manufacturing a solar cell module by the steps of: providing at least two bifacial solar cells; adjoining arrangement of the solar cells, wherein a gap is provided between the solar cells; providing a diffuse reflector in the gap area. The present invention also relates to such a solar cell module, wherein the diffuse reflector is disposed and configured such that it diffusely reflects the incident light and a portion of the diffusely reflected lights strikes on the solar cell through total reflection at the front boundary layer of the solar cell module.
