According to the invention, each solar panel is formed by at least two sections of solar elements, which are arranged on a base made of an electrically insulating material and covered by a temperature and moisture stable layer, coupled to each other and by a means for electrical connection embedded therein, and it is configured to receive at least one additional section. An edge section of each solar panel is equipped with a means for transformation of an output power, the means being a DC/DC transformer or a Schotky diode embedded into the base made of the electrically insulating material from a side of the panel faced towards the lamella, and coupled to a shared bus that is connected to a DC-to-AC current transformer. Therewith, a cross-section profile of the lamellas has a C-shape with curved edges, which form guides for mounting the solar panels in a longitudinal direction, wherein a distance between edges of the sections of the solar elements of the solar panel and edges of the electrically insulating base equals to a width of the edges of the lamella guides. ## Claims ### Claim 1 Photoelectric window blinds, which consist of a plurality of elongated lamellas arranged in parallel and connected between each other by at least two stripes, equipped with a drive for their assembling, disassembling and changing an inclination angle, which have solar panels mounted thereon, the panels are electrically connected between each other and equipped with a means for transmission of the obtained electric energy to external networks or storage means, characterized in that each solar panel is formed by at least two sections of solar elements arranged on a base made of an electrically insulating material and covered with a temperature and moisture stable layer, coupled to each other by a means of electric connection embedded therein, and are configured to receive at least one additional section; one edge section of each solar panel is equipped with a means for transformation of the output power, the means being a DC/DC transformer or a Schottky diode embedded into the base made of the electrically insulating material from a side of the panel faced towards the lamella, wherein the DC/DC transformer or the Schottky diode of each solar panel is coupled to a shared bus connected to a DC-to-AC current converter; wherein a cross-section profile of the lamellas has a C-shape with curved edges, which form lamella guides for mounting the solar panels in a longitudinal direction, wherein a distance between edges of the sections of the solar elements of the solar panel and edges of the electrically insulating base equals to a width of the edges of the lamella guides. ### Claim 2 (depends on 1) The blinds according to claim 1, characterized in that water-proof connectors of a plug-in type are used as the means for electric connection of the sections of the solar elements. ### Claim 3 (depends on 1) The blinds according to claim 1, characterized in that conductors, which are coupled to contacts, which are arranged on a reverse side of the sections of the solar panels, are used as the means for electric connection of the sections of the solar elements. ### Claim 4 (depends on 1) The blinds according to claim 1, characterized in that the solar panels are electrically connected between each other in a parallel fashion. ### Claim 5 (depends on 1) The blinds according to claim 1, characterized in that the solar panels are electrically connected between each other in a series-Parallel fashion. ### Claim 6 (depends on 1) The blinds according to claim 1, characterized in that the DC/DC transformer increases and stabilizes the voltage within a range of from 24 to 36 V. ### Claim 7 (depends on 1) The blinds according to claim 1, characterized in that the sections of the solar elements are made in a form of rectangles with cut top comers and wherein the overall area of the sections of the solar elements is at least 0.7 of the overall area of the solar panel, and the length of the electrically insulating base between the terminal edges of the solar panel and the edges of the corresponding sections of the solar elements does not exceed the length of said sections. ### Claim 8 (depends on 1) The blinds according to claim 1, characterized in that the drive is configured to change the inclination angle of the lamellas as a function of parameters of an illumination inside and/or outside a room.
