Description

Hybrid solar cell panel and hybrid solar power generation device

Technical Field

The present utility model relates to a hybrid solar power generation device and a hybrid solar cell panel usable in the same.

Background

The front side of the existing solar panel is a light-receiving power generation surface (a surface capable of generating power after receiving light), a power generation layer formed by a plurality of battery pieces is arranged on the inner side of a transparent protective layer (for example, photovoltaic glass) of the existing solar panel, the light-receiving power generation surface faces towards the sunlight illumination direction, the battery pieces convert light energy into solar energy, the battery pieces are connected to form electric energy output of the solar panel through certain connection, the battery pieces are not arranged on the back side, and the solar panel faces away from sunlight when in use. For example, chinese patent document CN214705951U discloses a single crystalline silicon solar cell capable of being quickly disassembled and assembled, comprising a toughened glass layer and a housing, wherein an EVA upper layer, a cell layer, an EVA lower layer, a TPT layer, a bottom layer and a protective layer are arranged below the toughened glass layer, the EVA upper layer, the cell layer, the EVA lower layer, the TPT layer, the protective layer and the bottom layer are mutually attached from top to bottom, sunlight can irradiate onto the cell layer through the toughened glass layer and the EVA upper layer, and then solar power generation is realized. The Chinese patent document CN discloses CN115639846A which discloses a portable easy-to-install single-shaft tracking photovoltaic power generation device, solar cells are installed on a turntable through corresponding connecting components, the rotation of the solar panels is controlled through the turntable and corresponding driving mechanisms to match with the lifting of the sun, the solar panels can be inclined, so that the solar panels can be vertically aligned with sunlight all the time when the inclination angles of the solar irradiation ground are different in different regions and different times, and then the solar panels can fully and more fully absorb the solar energy to finish the energy conversion work. The Chinese patent document CN211372217U discloses a solar energy-saving street lamp, which comprises upright posts, mounting frames arranged on the upright posts, lamp posts arranged on the mounting frames, lamp covers arranged on the lamp posts and bulbs arranged in the lamp covers, wherein fixing plates are symmetrically welded at the end parts of the upright posts, a connecting shaft is rotationally connected between the two fixing plates, and a bracket is welded on the outer side wall of the connecting shaft; because the sliding seat the junction of solar cell panel with the movable rod all is provided with the round pin axle, the movable rod cover is established outside the round pin axle, and with the round pin axle rotates to be connected, when the sliding seat is moved along recess promotion movable rod through the screw rod, the movable rod can promote or stimulate solar cell panel and overturn to suitable angle along the connecting axle through the support when moving, makes things convenient for the workman to carry out the adjustment of self-adaptation to solar cell panel's installation angle.

However, at different times, the solar radiation can change obviously, wherein the change not only comprises the change of the radiation angle, but also comprises the change of the radiation intensity and the radiation energy spectrum, and the power generation capability of the solar cell panel of different materials is different along with the change curves of the radiation intensity and the radiation energy spectrum. For example, currently, in a single crystal silicon solar cell, the power generation efficiency (photoelectric conversion efficiency) is significantly higher than that of other solar cells in a period where the illumination intensity (solar radiation intensity) is high, but the irradiation threshold is high, and when the illumination intensity is low to some extent, for example, in the case of the early and late period, the cloudy day, and the like, power generation cannot even be started, whereas a CIGS (copper indium gallium selenide) thin film solar cell can generate power by using such weak illumination although the power generation efficiency under strong sunlight irradiation is lower than that of a single crystal silicon (even polycrystalline silicon) solar cell. In addition, factors such as ambient temperature and radiation energy spectrum also influence the power generation capacity of different solar cells. While the performance of existing solar cells may continue to improve, or there may be more optimal electrical solar cells, as technology advances, it may be expected that there will be situations where different solar cells will each have advantages under different lighting conditions.

Therefore, in the prior art, although the solar position can be tracked and the orientation of the solar panel can be adjusted in real time to maximize the solar radiation energy which can be received, the adjustment cannot change natural factors such as illumination intensity and radiation energy spectrum, and good matching of the solar panel and the natural factors under different periods and different meteorological conditions cannot be realized, which is not beneficial to the maximization of the power generation capacity.

Detailed Description

Referring to fig. 1-6, the present utility model relates to a coagulated solar cell panel (simply referred to as a panel) of two configurations, one of which is a panel 10 of flat plate shape, which may be referred to as a panel a, and one of which is a panel 20 of folded plate shape, which may be referred to as a panel b.

The battery board a is provided with two large faces of one flat plate as light receiving power generation faces (faces provided with solar cells and capable of generating power after receiving illumination), namely, two light receiving power generation faces. This structure can be regarded as a structure in which two single-sided panels (panels having only one light-receiving power generation surface) are stacked with their front faces facing outward, and one back plate 11 is shared. In practice, according to the existing preparation mode of the solar cell panel, a light-receiving power generation layer, a light-transmitting protection layer (transparent surface layer) 13 outside the light-receiving power generation layer and the like can be respectively prepared on two sides of the same backboard; alternatively, the opposite sides of the two prepared corresponding solar panels are oppositely connected into a whole. For example, the opposite sides of the two panels may be bonded together, or the two panels may be fixedly attached together by a frame or any other suitable attachment means. The two back plates connected with each other are fixed together and can be regarded as a shared back plate.

The two solar cell layers can be selected according to the use requirements, environmental conditions and the like. In general, the main consideration is the illumination intensity (the illumination intensity that the solar panel can receive), and can be comprehensively considered in combination with weather conditions such as sunny proportion of the shade, ambient temperature and the like. For example, a solar cell adapted to the lighting conditions of noon and morning and evening can be selected as the first solar cell layer 16 and a solar cell adapted to the lighting conditions of morning and evening can be selected as the second solar cell layer 18 depending on the lighting conditions of noon and evening in the product use area.

As a preferred embodiment, the first solar cell layer may be a crystalline silicon solar cell layer, such as a monocrystalline silicon solar cell, and the second solar cell layer may be a thin film solar cell layer, particularly a CIGS thin film solar cell.

Other configurations involving solar panels may be in accordance with the corresponding prior art. For example, the outside of the solar cell layer is provided with photovoltaic glass (or photovoltaic glass layer) to achieve surface protection without affecting the solar cell layer to accept solar energy, an internal EVA layer, etc.

The solar cell selection related to the panel B can also be based on the mode. For example, the first solar panel 26 is a crystalline silicon solar panel, such as a monocrystalline silicon solar panel; the second solar panel 28 is a thin film solar panel, in particular a CIGS thin film solar panel.

A triangular panel frame may be provided as a mounting base for the first solar panel and the second solar panel, which are connected to form a folded panel. The section appearance of the battery plate frame is in an inverted V shape, and can mainly comprise side frames 21 on two sides and a cross rod 25 connecting the bottoms of the side frames, two solar battery plates are respectively and fixedly arranged on the surfaces of the two side frames, and the front surfaces of the battery plates face outwards to form an upward-leaning posture.

The inclination angles of the two panels (the first solar panel and the second solar panel) relative to the vertical line can be the same, and the inclination angle can be about 45 degrees (the included angle between the two panels and the vertical line is 45 degrees) according to actual needs, or can be determined according to other prior art or actual conditions.

Depending on the solar panels used, hybrid solar power plants are also divided into two types, one of which employs a panel a, which may be referred to as a power plant a, and the other of which employs a panel b, which may be referred to as a power plant b.

Both power generation devices are provided with a bracket for mounting the solar panel and a base 32 for mounting the bracket, and when rotation of the bracket is not required (for example, for some simple power generation devices), the bracket may be omitted or fixedly mounted on the base (see fig. 4). Other forms of mounting structures may be provided for mounting and securing to the ground (or other foundation) without the base.

As a preferred embodiment, a rotational connection (e.g., a bearing connection) between the bracket and the base is provided, and a bracket driving mechanism is provided for driving the bracket to rotate. One convenient way to implement this is to mount the support on a turntable 33 with a drive mechanism (the turntable may be fixedly mounted on the base or the turntable may be used directly as/instead of the base) and the drive mechanism of the turntable drives the rotating part of the turntable to rotate, thereby driving the support to rotate.

The sun-tracking system of the existing solar power generation device can be adopted to realize the sun-tracking and corresponding rotation control of the bracket.

For either power generation device, as a preferred embodiment, the bracket is provided with two posts 31, one on each side of the panel (panel a or panel b) to facilitate panel support.

The upper ends and the lower ends of the two stand columns can be respectively connected through corresponding support cross bars to form a fixed frame structure, and the middle part of the support cross bars positioned at the bottom can be provided with vertical connecting columns for connecting a base or a turntable and the like.

For the first power generation device, two ends of the battery plate are provided with rotating shafts (transverse shaft extensions) 12, and the rotating shafts are rotatably connected to the upright posts on two sides through corresponding bearings, wherein one transverse shaft extension penetrates through the upright post and is connected with an output shaft of a speed reduction motor 36 arranged on the upright post through a shaft coupling or in a transmission way through a transmission mechanism. When a plurality of battery plates which are distributed up and down in sequence are arranged, the same gear motor can be used for driving each battery plate to synchronously rotate through a proper transmission mechanism. When the solar system of the existing solar power generation device is used for controlling or driving the battery plate to rotate, the condition for replacing the light receiving surface of the battery plate can be set, for example, the illumination intensity for switching the light receiving surface is set, so that the turnover of the battery plate can be controlled through the solar system.

For the power generation device B, connecting rods can be arranged at two ends of the battery plate and fixedly connected to the upright posts at two sides.

For any power generation device, the number of the battery plates can be multiple and distributed up and down. In the case of the same light receiving area, the space occupied by the plurality of battery plates is obviously smaller than that occupied by only one battery plate.

For the first power generation device, the distance between the adjacent battery plates should ensure that the adjacent battery plates do not interfere with each other. Typically, in the case of a panel standing upright, there should be a gap between the upper and lower panels.

For the second power generation device, the spacing 29 between adjacent panels should ensure that the upper panel does not block illumination from the lower panel. Compared with the flat panel A, a larger distance (vertical distance) is needed between the adjacent panels B.

The power generation device can be matched with a sun-following system for use, the rotation of a bracket (for any power generation device) and the overturning of a battery plate (for a power generation device A) are controlled by the matched sun-following system, and the sun-following system comprises the following of the irradiation direction of sunlight, the measurement of the irradiation intensity and the control of each driving structure according to a set mode.
