Description

Double-sided photovoltaic panel and double-sided photovoltaic panel with a framed structure.
The subject of the invention is a double-sided photovoltaic panel and a double-sided photovoltaic panel with a two-component framed structure. The present disclosure concerns the structure of a photovoltaic panel which features two active sides that absorb light, in particular intended for mounting on support structures which feature a central load-bearing beam, cable tray or tracker device torsion beam running along the axis of symmetry and across photovoltaic panels.
Currently, photovoltaic systems are treated as long-term capital investments, the return on which is estimated to be 6 to 10 years, whereas photovoltaic panel service life can is up to 30 years. Photovoltaic panels continue to utilise only a small part of the solar energy they receive. Various solutions are employed to improve photovoltaic panel efficiency. Bifacial modules are relatively new solutions, i.e. double-sided modules, where both panel cell sides absorb sunlight. The other side of such a panel absorbs energy from reflected and dispersed light rays, therefore such factors as an installation site and a support structure which can reduce access to light, are extremely important. Multiple studies have shown that under standard conditions (panela with unrestricted access to light), in a position analogous to that of a photovoltaic panel installed on a support structure, and with a light reflectivity of 90%, the power generation output from the back side of a module can reach 40% of the power generation output from the front side. At the same time, ensuring uniform access to light also remains important to avoid hotspots on photovoltaic modules. This phenomenon is triggered by previous microcracks and fine damage of surfaces of photovoltaic panels which, due to their installation location on a roof or on the ground, are subjected to long periods of deep shadowing. Photovoltaic cells with insufficient solar irradiation develop a reverse current flow. This results in overheating of a damaged photovoltaic panel. Within the hotspot areas, the temperature may even exceed 250 degrees Celsius. As a result of overheating, damaged modules are further degraded. In extreme cases, this can even cause photovoltaic panel self-ignition.
There are double-sided photovoltaic panels designed in line with the state with an irregular arrangement of cells to counter hotspots, which is exemplified, e.g. by utility model no. CN209000924U. A solution is presented to route cabling in a manner which does not cast any shadow on cells by creating ducts for routing the wiring between the supply cells.
The state of the art is also known to include framed structures of photovoltaic panels, made with open profiles that are too intended to prevent shadowing the adjacent cells within a panel. Utility model no. CN207603547U presents an open profile solution for photovoltaic panel protection. The assumption behind the solution is to bond a photovoltaic panel into the profile defined in the patent claims.
The purpose of the solution is to provide a photovoltaic panel which is free from the issues of non-uniform irradiation of cell surfaces or operating temperature differentiation caused by traditional support structures in use.
According to the invention, a double-sided photovoltaic panel is characterised in that photovoltaic cells are arranged symmetrically in relation to the axis of symmetry of the photovoltaic panel and offset away from the axis of symmetry where the panel between offset cells is transparent. Photovoltaic panels with offset cells are intended for support structures with a central load-bearing beam or tracker device torsion beam and module wiring running along the photovoltaic panel axis of symmetry. The offset is located where the photovoltaic system components obscure reflected light that illuminates the bottom side of the photovoltaic panel. This solution is devoid of any shading of the central strip of cells. In addition, the rays of light pass through the transparent gap between the cells and are reflected from the surface of the beam to increase illumination, firstly, for the cells nearest to the beam, which would otherwise be the most shaded cells in the arrangement. Moreover, photovoltaic panels operating according to the said solution are characterised by a longer service life. The service life is longer because of the sustained uniform illumination and circulation of air, resulting in a uniform operating temperature panel cells. Such factors as the lack of localised overheating and ensured uniform illumination enhance efficiency of each cell, and consequently, of the entire panel. The said offset is advisable to be more than 1.5 cm and its maximum optimum limit is approximately 7.5 cm.
Preferably, the cells are offset from the side by at least 2 cm. Moving the cells from the external panel edges provides clearance for mounting panel frames without shading the outermost cells in the panel.
According to the invention, the double-sided photovoltaic panel with a framed structure is characterised in that the framed structure consists of two separate components, mutually symmetrical in relation to the axis of symmetry of the photovoltaic panel, and connected to the opposite side edges of the photovoltaic panel. As the two components are separate, the proposed panel frame leaves the lower edge and upper edge panel uncovered with a profile, which additionally exposes the panel edges to sunlight in areas where the cells would be shaded by traditional panel frames. This design also promotes more effective self-cleaning. Contaminants, especially sand, slide freely from the photovoltaic panel and meet no obstruction.
Preferably, the component comprises at least one central profile containing a lengthwise channel section adjusted to the photovoltaic panel thickness, where the side edge of the panel is adhesively bonded into the said channel section. Preferably, the component comprises one central profile and two corner profiles with a cross-section identical to the central profile, and connected at right angles to the central profile, and forming, via channels, a mounting trough with length adjusted to the photovoltaic panel, and the photovoltaic panel is inserted with its opposite edges into the mounting channel of the component, while the length of the comer profiles is equal at least to the width of the central profile and at most twice the width of the central profile. Additional comer profiles of the proposed structure protect the comers of the photovoltaic panel from damage and close the side edge of the panel in the trough designed, reinforcing the connection of the photovoltaic panel to the frame.
Preferably, each component comes with mounting holes parallel to the surface of the photovoltaic panel. This makes it possible to fasten the frame structure to the support structure using screws mounted along the frame structure outline. Thanks to this, the profiles used have a narrower lower surface, which is used as standard when installing the frame, and thus increases the access of light to the back side of the panel.
