Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panels, in particular to a curved solar photovoltaic panel. Background Art

[0002] Currently, there are three common types of mounting systems used in photovoltaic power plants: fixed mounting, adjustable-angle mounting, and tracking mounting. Tracking mounting is primarily designed for the Earth's rotation. Fixed and adjustable-angle mounting are designed for the Earth's revolution. The Earth completes one revolution per year, divided into four seasons: spring, summer, autumn, and winter. The equinox, summer solstice, autumnal equinox, and winter solstice mark the midpoints of each season. Because the Earth revolves around the Sun, the angle of solar radiation varies from season to season. The tilt of the Sun relative to the Earth at noon in the Northern Hemisphere is equal to the local latitude during the equinoxes, the local latitude minus the solar declination during the winter solstice, and the local latitude plus the solar declination during the summer solstice. This means that a smaller tilt angle is used during the period from the equinox to the summer solstice and the autumnal equinox, while a larger tilt angle is used during the period from the autumnal equinox to the winter solstice and the equinox.

[0003] Fixed mounting angles are adjusted based on the winter and summer solstices. Some regions have longer winters, while others have longer summers, so each region varies. Fixed mounting angles must be calculated for each region's characteristics. This angle provides the optimal energy generation for the region throughout the year. However, the drawback is that power generation may not be optimal in each season. Adjustable mounting angles, on the other hand, account for the varying angles of solar radiation throughout the year, offering four angles to accommodate the varying seasons. The vernal and autumnal equinoxes can also be combined into one angle, allowing the mounting to be adjusted three times a year. Due to the large number of photovoltaic mounting systems, including tens of thousands or even hundreds of thousands of modules, adjusting them once requires significant manpower, material resources, and time. Consequently, many photovoltaic power plants only adjust them twice. Designing with electric adjustment significantly increases costs, as self-generated electricity must be deducted from consumed electricity. Furthermore, enclosure costs are prohibitive, making it a rare practice in China.

[0004] In response to the problems existing in the above-mentioned fixed brackets and adjustable angle brackets, a new solar photovoltaic panel is needed that can meet both the summer and winter light radiation angles, and no longer requires manual angle adjustment, while meeting the requirements of all seasons. Utility Model Content

[0005] The purpose of the utility model is to provide a curved solar photovoltaic panel which meets both the summer light radiation angle and the winter light radiation angle and does not require manual angle adjustment.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A curved solar photovoltaic panel, characterized in that the solar photovoltaic panel is shaped as a circular arc surface that is convex upward, and the circular arc surface sequentially passes through endpoint A, point B, point C, and endpoint D, and endpoint D is higher than endpoint A;

[0008] The center of the arc surface is O, the radius of the arc surface is prefabricated as r, and the straight line extending vertically downward through the center O is set as OE;

[0009] The endpoint A is located below the center O, and the angle ∠AOE is set to the complementary angle of the winter solstice incident angle β at the winter solstice in the area where the solar photovoltaic panel is located;

[0010] The extension of line AO ​​intersects the circle where the arc surface lies at point C;

[0011] The angle of ∠BOE is set as the complementary angle of the incident angle α at the summer solstice in the region where the solar PV panel is located;

[0012] The extension line of the straight line BO intersects the circle on which the arc surface lies at the end point D.

[0013] In the above technical solution, the curved solar photovoltaic panel provided by the present invention has the following beneficial effects:

[0014] This new model utilizes the sunlight incident angles of the sun in winter and summer in the use area, and uses the winter and summer solar radiation angles as the two extreme angles of the year. With the midpoint of the photovoltaic panel as the center of the circle, the bottom point A of the winter photovoltaic panel and the vertex D of the summer photovoltaic panel are connected to form an arc surface, which meets both winter and summer requirements.

[0015] This new type of photovoltaic panel adopts a curved surface, which can meet the light radiation angle of both the summer solstice and the winter solstice. It no longer needs manual adjustment of the angle, so it can meet the requirements of all seasons, saving both total investment and operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0017] Figure 1 It is a structural schematic diagram of the solar photovoltaic panel disclosed by the utility model. DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 The solar photovoltaic panel is a curved surface. The overall shape of the solar photovoltaic panel is an upward convex arc surface. The arc surface passes through endpoint A, point B, point C and endpoint D in sequence. Endpoint D is higher than endpoint A.

[0020] The center of the arc surface is O, the radius of the arc surface is pre-set as r, and the straight line extending vertically downward through the center O is set as OE; the center O and the radius r of the arc surface are determined according to usage requirements and are known quantities, but the starting point of the arc surface, that is, the end points A and D, are unknown.

[0021] Set endpoint A below the center of the circle, O, and set the angle ∠AOE to the complementary angle of the winter solstice incident angle β at the location of the solar PV panel. That is, the angle between AO and the horizontal line passing through point A is the winter solstice incident angle β. This determines the location of endpoint A.

[0022] The extension line of straight line AO ​​intersects the circle where the arc surface is located at point C; endpoints A, point B and point C, endpoint D are distributed on both sides of point O.

[0023] The angle ∠BOE is set to the complementary angle of the summer solstice incident angle α in the region where the solar PV panels are located. That is, the angle between BO and the horizontal line passing through point B is the summer solstice incident angle α. This determines the location of point B. Endpoints A, B, C, and D are arranged in a clockwise direction.

[0024] The extension line of the straight line BO intersects the circle on which the arc surface is located at the end point D. The position of point D is thus determined, and thus the shape of the arc surface is determined. The size of the arc surface is determined according to the use requirements.

[0025] Specifically, first draw the center line OE. Then, draw line AC based on the winter solstice incident angle β for the region where the solar PV panel is located. For example, the length of line AC is equal to the PV panel length (2 × 2288 = 4576 mm), with the midpoint of line AC at O. Draw line BD based on the summer solstice incident angle α for the region where the solar PV panel is located. The length of line BD is equal to the PV panel length (2 × 2288 = 4576 mm), with the midpoint of line BD at O. Draw an arc with a radius of 2288 mm, intersecting lines AC and BD, respectively. This determines the locations of lines ABCD. Connecting lines ABCD sequentially with arcs forms the curved cross-section of the solar PV panel.

[0026] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
