Abstract: The present disclosure discloses a method and a device for measuring flatness of a flexible photovoltaic module, comprising: a measurement platform configured to fix a to-be-measured flexible photovoltaic module, height measurers respectively corresponding to wave crests and wave troughs on the to-be-measured flexible photovoltaic module, the plurality of height measurers being located above the measurement platform, and a lift rack on which the plurality of height measurers are disposed.

Abstract: The application discloses a solar cell component including at least two chip sets connected in series, wherein each chip set includes a plurality of chip units connected in parallel and a bypass diode connected in parallel with the chip units, each chip unit includes one or more photovoltaic chips connected in series, positive poles of the bypass diodes are connected with negative poles of the chip units, and negative poles of the bypass diodes are connected with positive poles of the chip units. The application further provides a solar panel with the solar cell component. The application not only can reduce the number of the bypass diodes, but also can improve economy of the product.

Abstract: The present disclosure provides a sunshade umbrella, which includes an umbrella rod, an umbrella body at an end of the umbrella rod, an umbrella handle at an opposite end of the umbrella rod, a solar cell component, a current output structure in the umbrella handle and in an electrical connection with the solar cell component, a first connection structure at the umbrella body and a second connection structure at the solar cell component. The solar cell component is detachably mounted to the umbrella body through detachable engagement between the first connection structure and the second connection structure.

Abstract: The disclosure provides a stress release method and device for packaging film of flexible photovoltaic module. The method comprises: placing a film to be cut on a loading platform; cutting the film with an insert such that an incision inclined relative to an edge of the film is formed on the film; and activating the feeding mechanism and driving the film to move along an axial direction thereof such that the insert moves out of the incision to a next position to be cut on the film. The stress release method and device according to the embodiments of the present disclosure can realize the release of the stress and shrinkage of the packaging film without changing the amount of the material of the packaging film, such that the risk of wrinkling during subsequent processing can be reduced.

Abstract: The present disclosure provides a laying device. The laying device includes: a fixing bracket, a weight pulley, and a working platform. With the laying device provided in the present disclosure, the weight pulley provides a fixed pressing force for the sealing tape, and the position of the weight pulley is set in advance, so that the sealing tape is subjected to a suitable pressing force, and the pressing uniformity of the sealing tape is good. Moreover, the weight pulley is movable relative to the edge of the photovoltaic module to be processed. Thus, for the photovoltaic module to be processed whose edge is linear, the sealing tape may be laid on the photovoltaic module to be processed along a straight line, and it can be ensured that the sealing tape is laid without bending, which ensures the appearance and performance of the photovoltaic module to be processed.
