This creation is about a solar snow melting structure, especially a solar snow melting structure heated on a solar module frame.

Since the solar power generation system in the snowy area is easy to reduce the power generation efficiency due to snow accumulation, the existing snow removal method removes the snow on the solar panel regularly or irregularly by manual labor to facilitate the photoelectric conversion of the solar panel.

The solar module comprises a frame, a solar cell array disposed on one side of the frame, a solar controller electrically connected to the solar cell array, and a battery electrically connected to the solar controller. The wires are electrically connected to the battery and the frame, respectively.

Preferably, the solar controller controls the battery to output current to the frame to raise the temperature of the frame.

Preferably, the frame is a material having a high electrical resistivity, and the material of the frame is aluminum or an aluminum alloy.

Preferably, the solar controller is disposed on the other side of the frame and disposed relative to the solar array.

FIG. 1 is a perspective view showing the solar snow melting structure of the present invention.

FIG. 2 is a view showing an embodiment of the solar snow melting structure of the present invention.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

As shown in FIG. 1 and FIG. 2 , the present invention provides a solar snow melting structure 100 including a solar module 110 and a plurality of wires 160 . The solar module 110 includes a frame 120, a solar cell array 130 disposed on one side of the frame 120, and a solar controller 140 electrically connected to the solar cell array 130. And a battery 150 electrically connected to the solar controller 140, respectively. The wires 160 are electrically connected to the battery 150 and the frame 120, respectively.

The solar module 110 (Photovoltaic Module) as shown includes a solar cell array 130 of series solar cells. The solar cell array 130 converts solar energy into direct current (DC) through, for example, a photovoltaic effect, and stores it in the battery 150, thereby increasing the photoelectric energy conversion efficiency per unit area, thereby increasing the amount of power generation.

Further, the solar module 110 is provided with, for example, a photoelectric conversion layer (not shown) to convert the energy of sunlight into DC power. The photoelectric conversion layer may be, for example, a semiconductor material composed of cerium (Si) as a main material or a cerium compound, or a semiconductor material composed of copper (Cu), indium (In), gallium (Ga), and selenium (Se). Or may include elements of group Ib such as copper (Cu) or silver (Ag), elements of group IIIb such as aluminum (Al), gallium (Ga) or indium (In) and elements of VIb such as sulfur (S), selenium ( The compound semiconductor material composed of Se) or ruthenium (Te) is not limited. Since the detailed structure and power conversion mode of the solar module 110 are prior art, no further details are provided herein.

The solar controller 140 controls the battery 150 to output current to the frame 120, and since the frame 120 is preferably a high resistance material such as aluminum or aluminum alloy. In detail, the resistance is the ability of an object to block the passage of current (charge). According to the law of resistance, the equation is RA=ρl, where R is the resistance, ρ is the resistivity (resistance coefficient), l is the length, and A is the cutoff. area. A linear relationship in which the resistance is proportional to the resistivity, that is, ρ indicates the ability of the material to block the flow of charge. When the conductivity is worse, the resistivity is larger, and the unit is Ω. m (ohm. meter). In general, when the temperature does not change much, there is a linear relationship between the resistivity ρ and the temperature. Therefore, the higher the resistivity, the higher the temperature of the material. Since the electrical resistivity of the aluminum alloy is about 2.83*10 ^-8 (Ω.m), the greater the electrical resistivity, the more difficult the current is transmitted in the aluminum alloy material, thereby increasing the temperature of the frame 120, thereby achieving the effect of heat and snow melting. .

As shown in FIG. 2, the solar snow melting structure 100 of the present embodiment is mounted on a roof 10 of a building or a platform (not shown) in an open space. In this embodiment, the roof 10 or platform preferably has an angle of inclination 20 between the horizontal plane. In general, the angle of inclination 20 is preferably between 20 and 40 degrees to absorb the greatest amount of sunlight and to increase the power generation efficiency of the solar energy.

The solar controller 140 is preferably disposed on the other side of the frame 120 and disposed relative to the solar array 130 to avoid direct damage from rain or snow. The solar controller 140 has protection circuit measures such as overcharge/overdischarge, short circuit, overload, anti-reverse connection, and automatic recovery. The battery 150 is charged by the solar controller 140, and the time, temperature or other functions of the battery 150 discharging the frame 120 are accurately controlled to effectively melt the snow accumulated on the solar module, and the solar module 110 cannot solve the light energy. The problem of converting into electricity.

In the embodiment shown in FIG. 1, the solar controller 140 further includes a battery 150 connected to the battery 150. The battery 150 of the present embodiment is disposed on the side of the roof 10, but in other different embodiments, the battery 150 can also be disposed under the solar module 110 and disposed side by side with the solar controller 140 to avoid rain or Invasion of snow water increases the service life.

When the battery 150 is connected to the frame 120 by the electric wire 160, when the voltage is released to the frame 120 of the aluminum alloy by the solar controller 140, the temperature of the frame 120 is easily raised due to the high resistivity of the frame 120, and the snow on the frame 120 is 30. melt. At this time, since the solar cell array 130 of the solar module 110 is usually made of glass, and the solar module 110 has an inclination angle 20, the snow 30 is slid on the frame 120 and melted.

It should be noted that the technology for heating and melting the heating frame 120 is to directly connect the battery 150 with the electric wire 160. The battery 150 provides direct current to heat the frame 120 without using an additional power source, and has the advantages of simple structure, low cost, and the like. The effect of environmental protection and energy saving.

In summary, the embodiments disclosed herein are to be considered as illustrative of the present invention and are not intended to limit the present invention. The scope of this creation is defined by the scope of the appended patent application and covers its legal equivalents and is not limited to the foregoing description.
