DETAILED DESCRIPTION

[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0063] First, the terms involved in this application are explained:

[0064] Double-glass photovoltaic module: refers to a solar photovoltaic module that mainly uses two pieces of glass as packaging materials to replace the traditional backboard material. The double-glass photovoltaic module can be designed to generate electricity on both sides. Not only can the front side absorb sunlight to generate electricity, but the back side can also use reflected light and scattered light to generate electricity, thereby improving the overall power generation efficiency. Specifically, the double-glass photovoltaic module is covered with a layer of glass on the front and back of the solar cell. These two layers of glass are usually tempered glass to provide higher mechanical strength and durability. Glass materials have better resistance to UV rays, moisture and corrosion, which makes the components have a longer service life in harsh environments. Glass materials have a higher fire resistance level and can improve the safety of photovoltaic systems. At the same time, the double-glass structure can provide better resistance to wind pressure and snow pressure, and is suitable for various complex installation environments.

[0065] Receiving aperture: refers to the light emitted from the sun or other light sources in photovoltaic module power generation. By using the receiving aperture, the light collection efficiency can be improved, thereby increasing the light intensity received by the photovoltaic module and improving the power generation efficiency of the photovoltaic module.

[0066] Optical fiber: refers to a long, thin fiber used to transmit optical signals, usually made of glass or plastic. It uses the principle of total internal reflection to transmit optical signals to distant places and is widely used in communications, medical treatment, sensors and other fields.

[0067] Focusing port: refers to the component used to collect and focus light in an optical system. It is usually used to concentrate light from a light source into a small area to increase the intensity of the light or achieve a specific optical effect.

[0068] Photoperiod: refers to the time period when the photovoltaic panels receive sunlight. The photoperiod can be divided based on the length of the photoperiod in a year. The photoperiod can be divided into a high photoperiod and a low photoperiod. The high photoperiod usually refers to a period of time with longer photoperiods each year, with longer sunshine hours and sufficient light; while the low photoperiod refers to a period of time with shorter sunshine hours and relatively insufficient light.

[0069] Radiation: refers to the total amount of radiation energy received per unit area per unit time. It measures the light energy radiated by the light source on a given area, usually expressed in watts per square meter (W / m 2 )express.

[0070] Electric energy meter: refers to a data table used to record the installation angle of the receiving aperture that meets the target radiation requirements in each lighting period. By monitoring the real-time radiation and the installation angle of the receiving aperture that meets the target radiation requirements in the electric energy meter, the installation angle of the receiving aperture can be adjusted to ensure that the photovoltaic modules can effectively receive and utilize light radiation in each lighting period, thereby maximizing power output and system efficiency.

[0071] Receiving aperture installation angle: refers to the installation direction or angle of the aperture, which affects the receiving range and efficiency of light. By adjusting the angle of the receiving aperture, the effect of optical fiber receiving light can be optimized to ensure that the optical fiber can receive sufficient light signals.

[0072] In the prior art, technicians mainly increase the light receiving rate of the back of the double-glass photovoltaic module by installing a reflector on the back of the double-glass photovoltaic module. However, the light intensity of the light reflected by the reflector that actually reaches the back of the photovoltaic module is weak, and the effect of increasing the light receiving rate of the back of the double-glass photovoltaic module by using the reflector is poor.

[0073] The present application provides a method for improving the utilization rate of light energy. Through the real-time radiation of the photovoltaic panel assembly in the current light period and the target radiation requirement corresponding to the current light period in a preset electric energy meter, it can be determined whether the real-time radiation of the photovoltaic panel assembly in the current light period meets the target radiation requirement. When the real-time radiation does not meet the target radiation requirement, the current installation angle of the receiving aperture is adjusted according to the installation angle of the receiving aperture corresponding to the target radiation requirement in the electric energy meter, thereby solving the problems of low light reception rate on the back side of the double-glass photovoltaic assembly and low light energy utilization rate of the double-glass photovoltaic assembly.

[0074] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0075] Figure 1 The system schematic diagram of the photovoltaic power generation system provided for this application is as follows: Figure 1 As shown, the photovoltaic power generation system of the present application includes a double-glass photovoltaic assembly 110, a receiving aperture 210, a receiving aperture bracket 211, an optical fiber 310, a fixing device 410, a lens system 510, a focusing port 610, an adjustment mechanism 710 and a box transformer 810, wherein:

[0076] The double-glass photovoltaic assembly 110 is used to convert received sunlight into electrical energy. The double-glass photovoltaic assembly 110 is connected to the receiving aperture 210, the control device 710 and the box transformer 810 through a cable, and transmits the generated electrical energy to the receiving aperture 210, the adjustment mechanism 710 and the box transformer 810. The box transformer 810 transmits the electrical energy generated by the double-glass photovoltaic assembly to the power grid or the load.

[0077] The receiving aperture 210 is used to collect light emitted from the sun or other light sources. The receiving aperture 210 is rotatably fixed on the fixing device 410 through a receiving aperture bracket 211 .

[0078] The optical fiber 310 is used to transmit the light collected by the receiving aperture 210 . The receiving end of the optical fiber 310 is arranged opposite to the light outlet of the receiving aperture 210 to ensure that the light can effectively enter the optical fiber 310 from the receiving aperture 210 .

[0079] The lens system 510 is used to focus the light transmitted by the optical fiber 310 into the light focusing port 610 to increase the intensity and concentration of the light, and the lens system 510 is arranged between the optical fiber 310 and the light focusing port 610. The light focusing port 610 is used to evenly guide the light to the back of the double-glass photovoltaic module 110, and the output end of the light focusing port 610 is arranged opposite to the double-glass photovoltaic module 110.

[0080] The adjustment mechanism 710 is used to adjust the installation angle of the receiving aperture 210 , and the adjustment mechanism 710 is connected to the receiving aperture 210 via the fixing device 410 .

[0081] Figure 2 A schematic diagram of a method for improving light energy utilization provided in this application, such as Figure 2 As shown, the method includes:

[0082] S201, determining the current illumination period of the photovoltaic panel assembly and the real-time radiation amount of the photovoltaic panel assembly in the current illumination period.

[0083] Among them, by obtaining the local time, the current light period of the photovoltaic panel assembly can be determined. Specifically, April to August each year can be divided into a high light period, and January to March each year and September to December each year can be divided into a low light period. When the local time of the photovoltaic panel assembly is adjusted to June, the current light period of the photovoltaic panel assembly is a high light period; when the local time of the photovoltaic panel assembly is adjusted to December, the current light period of the photovoltaic panel assembly is a low light period.

[0084] The real-time radiation amount of the photovoltaic panel assembly during the current illumination period can be measured by a radiation sensor (such as a radiometer), wherein the radiation sensor can be installed above or near the photovoltaic panel assembly.

[0085] S202. According to the current illumination period, determine the target radiation requirement corresponding to the current illumination period from a preset electric energy meter, wherein the electric energy meter is used to record the installation angle of the receiving aperture that meets the target radiation requirement in each illumination period.

[0086] In the embodiment of the present application, the illumination period includes a high illumination period and a low illumination period, and the determination of the preset electric energy meter includes:

[0087] Collect historical radiation data and historical installation angle data of the receiving aperture at each time period during the high light period, as well as historical radiation data and historical installation angle data of the receiving aperture at each time period during the low light period;

[0088] Based on the historical radiation data of each period during the high light period, the monthly average radiation during the high light period is determined;

[0089] Based on the historical radiation data of each period during the low light period, the monthly average radiation during the low light period is determined;

[0090] According to the historical installation angle data of the receiving aperture at each time period during the high light period, determine the installation angle of the receiving aperture corresponding to the monthly average radiation during the high light period;

[0091] According to the historical installation angle data of the receiving aperture at each time period during the low light period, determine the installation angle of the receiving aperture corresponding to the monthly average radiation during the low light period;

[0092] A preset electric energy meter is obtained according to the illumination period, the average radiation amount corresponding to the illumination period, and the installation angle of the receiving aperture corresponding to the average radiation amount.

[0093] Table 1 is the electric energy meter of this application, as shown in Table 1:

[0094] Photoperiod Average radiation dose Receiving aperture installation angle High light period (April-August) <![CDATA[189.72kWh / m 2 / month]]> 15°-25° Low light period (September to March) <![CDATA[90.34kWh / m 2 / month]]> 40°-50°

[0095] Table 1

[0096] When the high light period is from April to August, the historical radiation data from April to August can be averaged and the average radiation from April to August can be obtained as 189.72 kWh / m 2 / month. The maximum and minimum values ​​of the historical installation angle data of the receiving aperture during the high light period from April to mid-August can be collected and used as the two extreme values ​​of the installation angle of the receiving aperture, thereby obtaining the installation angle of the receiving aperture during the high light period from April to August. For example, when the maximum value of the historical installation angle data of the receiving aperture during the high light period from April to mid-August is 25° and the minimum value is 15°, the installation angle of the receiving aperture is 15° to 25°.

[0097] When the low light period is from September to March, the historical radiation data from September to March can be averaged and the average radiation from September to March can be obtained as 90.34 kWh / m 2 / month, and then collect the maximum value 50° and the minimum value 40° of the historical installation angle data of the receiving aperture during the low light period from September to mid-March, and use them as the two extreme values ​​of the receiving aperture installation angle, and then obtain the receiving aperture installation angle during the low light period from September to March is 40° to 50°.

[0098] S203: If the real-time radiation amount does not meet the target radiation amount requirement, the current installation angle of the receiving aperture is adjusted according to the installation angle of the receiving aperture in the electric energy meter.

[0099] Among them, the real-time radiation can indicate the light intensity received by the photovoltaic panel during the current light period, reflecting the immediate performance of the photovoltaic panel. If the real-time radiation is high, the photovoltaic panel can generate more electricity. If the real-time radiation is low, the electricity generated by the photovoltaic panel will be reduced. When the real-time radiation does not meet the target radiation requirement, it means that the light intensity received by the photovoltaic panel during the current light period is lower than the average light intensity received by the photovoltaic panel during the current light period. At this time, the current installation angle of the receiving aperture can be adjusted according to the installation angle of the receiving aperture corresponding to the target radiation requirement in the electric energy meter.

[0100] In the embodiment of the present application, according to the current illumination period, the target radiation requirement corresponding to the current illumination period is determined from a preset electric energy meter, including:

[0101] Get the current environmental conditions of the photovoltaic panel assembly during the current light period;

[0102] According to the current illumination period, determining the initial radiation requirement corresponding to the current illumination period and the environmental conditions corresponding to the initial radiation requirement from a preset electric energy meter;

[0103] If the current environmental conditions and the environmental conditions do not correspond, the initial radiation requirement is adjusted according to the current environmental conditions and the environmental conditions to obtain the target radiation requirement.

[0104] Table 2 is an electric energy table including environmental conditions for this application, as shown in Table 2:

[0105]

[0106] Among them, the duration of sunshine can directly affect the amount of radiation. Long sunshine duration means that the PV system will have more radiation in a day and the PV system will generate more electricity. At the same time, weather conditions affect the amount of radiation by affecting the intensity of radiation reaching the ground. For example, sunny days provide the most radiation, while cloudy days, clouds, rain and other weather conditions will reduce the radiation.

[0107] When the current light period is the high light period from April to August, the environmental conditions during the high light period are 20-25 days of sunshine per month and 20-25 days of sunny days per month. The average radiation during the high light period is 189.72 kWh / m 2 / month, if the current environmental conditions correspond to the environmental conditions during the high light period, the average radiation during the high light period can be used as the target radiation requirement; if the current environmental conditions do not correspond to the environmental conditions during the high light period, the average radiation during the high light period will be used as the initial radiation, and then according to the difference between the current environmental conditions and the environmental conditions during the high light period, the initial radiation requirement is adjusted to obtain the target radiation requirement, and then according to the real-time radiation and the target radiation requirement, it is determined whether to adjust the current installation angle of the receiving aperture.

[0108] In the embodiment of the present application, if the current environmental condition and the environmental condition do not correspond, the initial radiation requirement is adjusted according to the current environmental condition and the environmental condition to obtain the target radiation requirement, including:

[0109] Obtain the number of sunny days and sunshine duration corresponding to the initial radiation requirement, as well as the current number of sunny days and sunshine duration;

[0110] Determine an adjustment factor for the initial radiation requirement based on the difference between the current number of sunny days and the number of sunny days corresponding to the initial radiation requirement, and the difference between the current sunshine duration and the sunshine duration corresponding to the initial radiation requirement, wherein the adjustment factor is in the range of 0 to 1;

[0111] Multiply the adjustment factor by the initial radiation requirement to obtain the target radiation requirement.

[0112] For example, during the high-intensity period from April to August, the sunshine duration is 250h-300h / month, and there are 20-25 sunny days / month, corresponding to an initial radiation of 189.72kWh / m2 / month, if the current environmental conditions in May show that the sunshine duration is 200h / month and there are 15 sunny days / month, 200h / month is not within the range of 250h-300h / month, and 15 days / month is not within the range of 20days-25days / month, then determine the degree of difference between 15days / month and 20days-25days / month, and the degree of difference between 200h / month and 250h-300h / month.

[0113] Among them, the difference between 200h / month and the sunshine duration range of 250h-300h / month during the high light period can be expressed by the proportion of the current sunshine duration to the sunshine duration during the high light period. Therefore, the difference between 200h / month and 250h-300h / month is (200 / 300, 200 / 250), that is, 0.67 to 0.8; the difference between the number of sunny days in May 15 days / month and the number of sunny days 20-25 days / month during the high light period can be expressed by the proportion of the current sunny days to the sunny days during the high light period. Therefore, the difference between 15 days / month and 20 days-25 days / month is (15 / 25, 15 / 20), that is, 0.6 to 0.75.

[0114] In order to facilitate the subsequent calculation of the adjustment factor, the final difference in sunshine duration can be expressed as 0.735, the median of 0.67 to 0.8, and the final difference in sunny days can be expressed as 0.675, the median of 0.6 to 0.75. The adjustment factor satisfies:

[0115] Adjustment factor = (difference in sunshine duration + difference in number of sunny days) ÷ 2

[0116] Therefore, the adjustment factor for May = (0.735 + 0.675) ÷ 2 = 0.705.

[0117] The target radiation dose meets:

[0118] Target radiation dose = initial radiation dose × adjustment factor

[0119] Therefore, the target radiation in May is 133.58 kWh / m when the sunshine duration is 200 h and the number of sunny days is 15. 2 / month, when the real-time radiation is less than 189.72kWh / m 2 / month, but greater than 133.58kWh / m 2 / month, there is no need to adjust the current installation angle of the receiving aperture.

[0120] In the embodiment of the present application, if the real-time radiation amount does not meet the target radiation amount requirement, after adjusting the current installation angle of the receiving aperture according to the installation angle of the receiving aperture in the electric energy meter, the method further includes:

[0121] Transmitting the light received by the receiving aperture to the optical fiber;

[0122] Focusing and direction-adjusting the light outputted from the optical fiber;

[0123] The light after focusing and direction adjustment is transmitted to the focusing port, and the optical fiber is evenly transmitted to the back of the photovoltaic module through the focusing port.

[0124] Among them, the light collected by the optical fiber transmission receiving aperture can effectively transmit the light and reduce the loss of light during the transmission process. Focusing the light through optical elements (such as lenses or lenses) can make the light concentrate at the focusing port, increase the intensity of the light, and adjust the light direction to ensure that the light is transmitted to the focusing port to avoid scattering and deviation. The focusing port can evenly transmit the light to the back of the photovoltaic module, thereby increasing the light receiving rate of the photovoltaic module.

[0125] The embodiment of the present application provides a method for improving the utilization rate of light energy. Through the real-time radiation of the photovoltaic panel assembly in the current light period and the target radiation requirement corresponding to the current light period in the preset electric energy meter, it can be determined whether the real-time radiation of the photovoltaic panel assembly in the current light period meets the target radiation requirement, and when the real-time radiation does not meet the target radiation requirement, the current installation angle of the receiving aperture is adjusted according to the installation angle of the receiving aperture corresponding to the target radiation requirement in the electric energy meter. This method is used to achieve the effect of improving the back light receiving rate of the double-glass photovoltaic assembly and improving the light energy utilization rate of the double-glass photovoltaic assembly.

[0127] Before determining the current illumination period of the photovoltaic panel assembly and the real-time radiation amount of the photovoltaic panel assembly in the current illumination period, the method further includes:

[0128] Obtain the length of the photovoltaic panel assembly, the angle between the photovoltaic panel assembly and the ground, and the geographical latitude of the photovoltaic panel assembly;

[0129] The distance between the photovoltaic panel assembly and the receiving aperture is determined according to the length of the photovoltaic panel assembly, the angle between the photovoltaic panel assembly and the ground, and the geographical latitude of the photovoltaic panel assembly, where the distance satisfies:

[0130]

[0131] Wherein, D is the distance between the photovoltaic panel assembly and the receiving aperture, L is the length of the photovoltaic panel assembly, β is the angle between the photovoltaic panel assembly and the ground, and φ is the geographical latitude of the photovoltaic panel assembly.

[0132] The tilt angle of the photovoltaic panel will affect the incident angle of sunlight, thus affecting the efficiency of the receiving aperture in collecting light from the sun or other light sources. By determining the distance between the photovoltaic panel assembly and the receiving aperture through the length of the photovoltaic panel assembly, the angle between the photovoltaic panel assembly and the ground, and the geographical latitude of the photovoltaic panel assembly, the sunlight will not be blocked by the photovoltaic panel during the noon period, so that more sunlight can be received by the receiving aperture, and then the sunlight will be transmitted to the back of the photovoltaic assembly through optical fiber, lens and focusing port, thereby improving the light receiving rate of the photovoltaic panel assembly.

[0136] Compare the angle between the sun's rays and the ground with the angle between the normal of the receiving aperture and the ground to obtain an angle comparison result;

[0137] If the angle comparison result indicates that the angle difference between the angle between the sunlight and the ground and the angle between the normal of the receiving aperture and the ground is not within the range of -5° to 5°, the control adjustment mechanism adjusts the angle between the normal of the receiving aperture and the ground until the angle difference is within the range of -5° to 5°.

[0138] The angle between the sunlight S and the ground is angle β1, and the angle between the normal line R of the receiving aperture and the ground is angle β2. When the difference between angle β1 and angle β2 is infinitely close to 0, the sunlight can be more effectively received by the receiving aperture and transmitted through the optical fiber. In this embodiment, when the angle β1 between the sunlight and the ground and the angle β2 between the normal line of the receiving aperture and the ground are in the range of -5° to 5°, the adjustment mechanism does not need to be activated to adjust the angle between the normal line of the receiving aperture and the ground; when the angle difference between the angle β1 between the sunlight and the ground and the angle β2 between the normal line of the receiving aperture and the ground is not in the range of -5° to 5°, the adjustment mechanism is controlled to adjust the angle between the normal line of the receiving aperture and the ground until the angle difference is in the range of -5° to 5°.

[0139] In the embodiment of the present application, determining the angle between the sunlight and the ground, and the angle between the normal of the receiving aperture and the ground, includes:

[0140] Obtain the solar declination angle, the solar hour angle at the receiving aperture, the geographic latitude at the receiving aperture, and the angle between the normal of the receiving aperture and the ground, wherein the solar hour angle is determined according to the true solar time, and the true solar time is determined according to the geographic longitude at the receiving aperture and the time difference;

[0141] Determine the angle between the sun's rays and the ground based on the solar declination, solar hour angle, and geographic latitude.

[0142] Among them, the angle h between the sun's rays and the ground satisfies:

[0143]

[0144] h is the solar altitude angle, is the local latitude, δ is the solar declination angle, and ω is the solar hour angle.

[0145] The solar declination angle is the angle between the sun's rays and the Earth's equatorial plane, which changes with the date.

[0146]

[0147] The solar declination angle can be obtained by calculation or table lookup. The solar declination angle δ satisfies:

[0148] δ is the solar declination angle, and N is the number of days starting from January 1st.

[0149] Among them, the solar hour angle ω represents the time of the sun relative to the local noon (i.e. solar noon), and the solar hour angle ω satisfies:

[0150] ω=15°×(ST-12)

[0151] ST=UT+4×(λ-120)+δt

[0152] δt=0.1645×sin[2×(N-81)]-0.025×sin[4×(N-81)]-0.1255×cos[0.5×(N-81)]-0.0075

[0153] ST represents true solar time, UT represents universal time, λ represents the longitude at the receiving aperture, and δt represents the time difference.
