Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic panel for a roof and an installation method thereof. Background Art

[0002] The deviation of the installation angle of the photovoltaic panel will cause the refraction angle of the photovoltaic panel to the sun to change, and the sunlight collection rate will be affected. The existing technology improves construction safety by assembling the photovoltaic panels on a flat photovoltaic panel installation platform and then lifting the entire platform to complete the installation of the photovoltaic panels. However, the inclination of the photovoltaic panels is not taken into consideration. The unqualified inclination angle of the photovoltaic panels will lead to a decrease in the sunlight collection rate.

[0003] Chinese patent application number: CN201510922207.9 discloses a photovoltaic panel installation method. This method changes the traditional photovoltaic panel installation method, which requires the panels to be installed on a photovoltaic panel bracket arranged on an inclined surface, to assembling the photovoltaic panels on a photovoltaic panel mounting platform arranged on a flat surface, and then lifting the entire panel into place to complete the installation. The present invention can effectively reduce the difficulty of construction, save construction costs, and improve construction safety. It can be seen that the photovoltaic panel installation method has the following problems: it does not take into account the inclination of the photovoltaic panel, and the unqualified inclination angle of the photovoltaic panel leads to a reduced sunlight collection rate. Summary of the Invention

[0004] To this end, the present invention provides a photovoltaic panel for a roof and an installation method thereof, so as to overcome the problem in the prior art that the inclination of the photovoltaic panel is not taken into consideration and the inclination angle of the photovoltaic panel is unqualified, resulting in a reduced sunlight collection rate.

[0010] A fixing plate, which is arranged at the bottom of the column and is used to fix the column;

[0011] An analysis unit is used to analyze whether the installation of the photovoltaic panel is qualified based on the shortest distance between the characteristic point on the photovoltaic panel and the plane of the ceiling, to conduct a secondary analysis of whether the installation of the photovoltaic panel is qualified based on the size of the photovoltaic panel, and to analyze the reasons for unqualified installation of the photovoltaic panel based on the shortest distance.

[0012] The present invention provides a method for installing photovoltaic panels on a roof, including:

[0013] Step S1: Obtain the dimensions of each photovoltaic panel, determine and mark the characteristic points of each photovoltaic panel to be installed, place the photovoltaic panel at the pre-installation point on the ceiling, fix each fixing plate according to the preset pre-tightening force, adjust the inclination angle of the photovoltaic panel, and tighten the fixing plate;

[0014] Step S2: Obtain the position of the characteristic points of each photovoltaic panel, calculate the shortest distance between the coordinates of a single characteristic point and the ceiling plane, and analyze whether the installation of a single row of photovoltaic panels is qualified based on the shortest distance;

[0015] Step S3: performing a secondary determination on whether the installation of the single-row photovoltaic panels is qualified based on the size of the photovoltaic panels, analyzing the reasons for the unqualified installation of the single-row photovoltaic panels based on the mean value of the shortest distances, and adjusting the preload force of the photovoltaic panels based on the analysis results;

[0016] Step S4: Install the photovoltaic panels according to the adjusted parameters.

[0017] Furthermore, in step S2, the coordinates of the characteristic points of each photovoltaic panel in the single row of photovoltaic panels are obtained, and based on the shortest distance between the coordinates of the characteristic points and the ceiling plane, the average of the shortest distances is calculated, and based on the average distance, whether the installation of the single row of photovoltaic panels is qualified is determined.

[0018] If the distance mean is less than or equal to the first preset distance mean, it is determined that the installation of the single row of photovoltaic panels is unqualified, and the reason for the unqualified installation is that the bracket is unqualified;

[0019] If the distance mean is greater than the first preset distance mean and less than or equal to the second preset distance mean, it is determined that the installation of the single row of photovoltaic panels is qualified;

[0020] If the distance mean is greater than the second preset distance mean and less than or equal to the third preset distance mean, it is preliminarily determined that the installation of the single row of photovoltaic panels is unqualified, and a secondary determination is made on whether the installation of the single row of photovoltaic panels is qualified based on the size of the photovoltaic panels;

[0021] If the distance mean is greater than the third preset distance mean, it is determined that the installation of the single row of photovoltaic panels is unqualified, and the reason for the unqualified installation is analyzed based on the distance mean.

[0022] Furthermore, under the condition that the bracket is determined to be unqualified, the angle of the single-row bracket is increased based on the mean difference between the first preset distance mean and the distance mean, wherein,

[0023] The increase in angle of single-row stents was positively correlated with the mean difference.

[0024] Furthermore, the secondary determination of whether the installation of a single row of photovoltaic panels is qualified based on the size of the photovoltaic panels includes:

[0025] Whether the installation of the single-row photovoltaic panel is qualified is determined based on the size difference between the actual size of the photovoltaic panel and the preset size, wherein:

[0027] If the size difference is greater than the preset size difference, it is determined that the installation of the single row of photovoltaic panels is qualified, and it is determined that there is an error in the analysis.

[0028] Furthermore, under the condition that the analysis determines that there is an error, the first preset distance mean is increased based on the difference between the size difference and the preset size difference, wherein,

[0029] The increase in the first preset distance mean is positively correlated with the difference.

[0030] Furthermore, under the condition that the installation of the single-row photovoltaic panels is determined to be unqualified, the reason for the unqualified installation of the single-row photovoltaic panels is determined based on the mean distance difference between the mean distance and the third preset mean distance, wherein:

[0031] If the distance mean difference is less than or equal to the preset distance mean difference, it is determined that the reason for the unqualified installation of the single-row photovoltaic panel is that the pre-tightening force is unqualified;

[0032] If the distance mean difference is greater than the preset distance mean difference, the reason why the installation of the single row of photovoltaic panels is unqualified is determined based on the variance analysis of the shortest distances.

[0033] Furthermore, under the condition that the preload force is determined to be unqualified, the preload force is reduced based on the ratio of the distance mean difference to the preset mean distance difference, wherein,

[0034] The reduction amount of the preload force is proportional to the ratio of the distance mean difference to the preset mean distance difference.

[0035] Furthermore, the reasons for the unqualified installation of the single-row photovoltaic panels based on the variance analysis of the shortest distances include:

[0036] Calculating the variance of the shortest distance and determining the reason for the unqualified installation of the single-row photovoltaic panel based on the variance, wherein:

[0037] If the variance is less than or equal to the preset variance, it is determined that the reason for the unqualified installation of the single-row photovoltaic panel is that the pre-tightening force is unqualified;

[0038] If the variance is greater than the preset variance, it is determined that the reason for the unqualified installation of the single-row photovoltaic panel is that the bracket is unqualified, and a bracket maintenance notice is issued.

[0039] Compared with the prior art, the beneficial effect of the present invention lies in that the photovoltaic panel is first pre-fixed in the present invention, and the fixing plate is tightened when the adjustment of the photovoltaic panel angle is completed to finally fix the photovoltaic panel, thereby avoiding unqualified photovoltaic panel angles due to premature fixation of a single fixing point of the fixing plate, thereby affecting subsequent installation. Whether the angle of the photovoltaic panel is qualified is analyzed based on the distance between the characteristic point on the photovoltaic panel and the pre-ceiling plane after installation, thereby avoiding deviations in the tilt angle of the photovoltaic panel due to different fixing forces during the fixing process of each photovoltaic panel, thereby ensuring the sunlight collection rate.

[0040] Furthermore, in the present invention, the tilt angle of the photovoltaic panel is adjusted by adjusting the height difference between the first telescopic column and the second telescopic column, thereby improving the fixation of the photovoltaic panel and achieving real-time adjustment of the tilt angle of the photovoltaic panel.

[0041] Furthermore, in the present invention, the larger the area of the photovoltaic panel, the greater the influence of the tilt angle on the sunlight collection situation. The installation situation of the photovoltaic panel is analyzed according to the size of the photovoltaic panel, which improves the control accuracy of the installation situation of the photovoltaic panel and improves the accuracy of the analysis of the installation situation of the photovoltaic panel.
