It will be understood that when an element is referred to as being "mounted" to another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

The photovoltaic module matrix structure with 10-degree inclination provided in this embodiment is shown in fig. 1, and includes two module groups, namely an east-west module group 1 distributed towards the east-west direction and a north-south module group 2 arranged towards the north-south direction.

Because the matrix structure is mostly arranged in the northern hemisphere, the module group can be selected according to different latitudes by dividing the module group into two modes. In areas with low latitude, the module groups distributed in the east-west direction are selected, so that the solar module groups can cater to the rising and falling track of the sun, and the solar energy absorption effect of the photovoltaic module matrix is improved; in high-latitude areas, due to oblique irradiation of sunlight, the solar energy utilization effect is optimized by selecting the north-south module group 2 to improve the light energy absorption amount in effective daily time.

As shown in fig. 1 to 3, the east-west module group 1 and the north-south module group 2 each include a base 3, a photovoltaic panel 4, front and rear feet 5, and a ballast 6. The base 3 comprises two non-block rails 31 arranged in parallel, the two non-block rails 31 being fixed to the roof for connecting the mounting surface of the roof and mounting the module group. The photovoltaic cell panel 4 is obliquely installed on the base 3 to receive sunlight and collect solar energy.

At the same time, at least one ballast 6 is provided on each base 3 in order to promote the stability of the matrix structure as a whole.

The difference between the east-west module group 1 and the north-south module group 2 is that: the photovoltaic cell panels 4 of the east-west module group 1 incline towards the east and the west respectively and form an isosceles triangle structure with the base 3; and a plurality of photovoltaic cell panels 4 of the north-south module group 2 incline towards the south and form a right triangle structure with the base 3.

Meanwhile, a north-south air guard plate 11 for closing the opening is arranged on the opening in the north-south direction of the east-west module group 1; the east-west air guard 21 is arranged on the east-west opening of the north-south module group 2, and the north-north air guard 22 is arranged on the north face of the north-south module group 2. The joint of two adjacent photovoltaic cell panels 4 of the north-south module group 2 is directly fixed with the mounting surface through the front foot 5, the rear foot 5 and the mounting seat 53, and the base 3 is not arranged.

Since the solar photovoltaic module is mainly arranged in China, the solar photovoltaic module is mainly arranged in southeast and southwest in summer, and is mainly arranged in northwest and northeast in winter, and is generally in east-west direction, the northeast-west direction module group 1 is arranged into an isosceles triangle structure inclined in east-west direction, so that the force of pressing down the photovoltaic cell panel 4 can be generated by the east-west direction module group, the stability of the whole structure is improved, and the north-south air defense plates 11 are arranged on openings in the north-south direction to prevent the air flow in the south-north direction from entering the northeast-west direction module group 1 and affecting the stable structure of the northeast-west direction module group 1.

The north-south module group 2 forms an inclined right triangle structure due to the inclination requirement caused by latitude factors, and the opening in the other directions is closed through the east-west air guard 21 and the north-side air guard 22, so that the north-south module group 2 can be prevented from being turned over due to overlarge wind power, and the stability of the north-south module group 2 is improved.

As shown in fig. 3 to 4, in order to further improve the wind-proof performance of the north-south module group 2, the north wind guard in the present utility model includes a top connection plate 221, a middle wind guard 222 and a bottom connection plate 223 connected in sequence from top to bottom, and the top connection plate 221 and the bottom connection plate 223 are respectively fixed at the top and bottom of the front and rear legs 5.

An air inlet 23 is formed between the top connecting plate 221 and the photovoltaic cell panel 4, and an air outlet 24 is formed between one end of the photovoltaic cell panel 4 away from the north air guard 22 and the mounting surface.

As shown in the figure, after the inclined middle air guard 222 is provided, the north wind directly blowing to the north air guard 22 is guided by the middle air guard 222, and forms an air flow swirling to the bottom rear, so that part of the rear wind force can be offset, and the influence of the north wind on the north-south module group 2 can be reduced. And part of the air flow is guided by the cambered top connecting plate 221, enters the module group through the air inlet 23, flows along the direction of the photovoltaic cell panel 4, and is finally discharged through the air outlet 24 at the other side, so that the north wind is divided into a plurality of strands, and the influence of the north wind on the stability of the north-south module group 2 is reduced.

In addition, the installation inclination angle of the photovoltaic cell panel 4 is generally affected by local latitude conditions and needs to be correspondingly adjusted, and the stability is easily reduced due to the fact that the photovoltaic module matrix is simple in structure, low in cost and weight and therefore excessive in inclination angle. After the sunlight irradiation condition and the wind power influence are integrated, the installation inclination angle of the photovoltaic cell panel 4 is determined to be 10 degrees, so that the best solar energy utilization effect can be achieved under the condition of ensuring the best overall stability of the photovoltaic module matrix structure.
