Description

[0001] The present invention relates to a solar photovoltaic module having a heat generating function,

The present invention relates to a photovoltaic power generation module having a heat generating function, and more particularly, to a photovoltaic power generation module having a heat generating function in a photovoltaic power generation module and capable of dissolving snow accumulated in the photovoltaic power generation module, Module.

Much of the energy that is commonly used is energy from fossil fuels. However, since the amount of such fossil fuels is limited, it is inevitably exhausted sometime and there is a problem of causing air pollution and greenhouse effect by discharging various pollutants and carbon dioxide. Nuclear energy also has a problem of nuclear waste disposal.

Because of these problems, the need for environmentally friendly alternative energy development is growing, and renewable energy is an eco-friendly alternative to existing energy sources. Solar energy, wind power, tidal power, and geothermal power are examples of renewable energy. Among them, solar energy is the most popular renewable energy.

A method of generating electricity using solar energy can be divided into solar power generating electricity by rotating the turbine with heated water using solar heat and solar power generating electricity directly using solar power, This noise, heat dissipation, and vibration are attracting much attention because of its small merit.

However, the photovoltaic power generation has a disadvantage in that a large installation area is required and the power generation cost is relatively high, so that a method for increasing the efficiency of the photovoltaic power generation is needed. Photovoltaic power generation uses photovoltaic power generated by the photovoltaic effect and stored in a battery, and the solar cell mainly consists of a semiconductor junction. The basic principle of photovoltaic power generation is that when energy larger than the forbidden band width of a semiconductor is injected into a solar cell composed of a semiconductor PN junction from solar light, the pair of electrons and electrons are excited in the N layer and the P layer, And the flow of electric current is generated by moving to the surface of the P layer and the N layer. This phenomenon is called a photovoltaic effect, and when the load is connected to the electrodes at both ends, current flows through the operation principle. Therefore, in order to increase the power generation efficiency of the solar cell, it is necessary to make the maximum amount of solar light reach the solar panel.

The photovoltaic power generation system has a great effect in that there is no generation of pollution source, but there is a problem in that the initial installation cost is high and the power generation efficiency is lowered in the winter season when the sunlight time is short.

In particular, if snow accumulates on the light collecting plate during the winter season, solar power can not enter the PV module, so that it can not be generated. In view of the recent trend of PV power generation facilities, it is impossible to remove the accumulated snow.

Korean Patent No. 10-1038345 discloses a solar power generation module having a heating film.

The photovoltaic module has a structure in which a heating film with a built-in heating wire is installed on a solar photovoltaic panel to generate heat. However, since the sunlight passes through the heating film and reaches the solar panel, light loss is generated by the heating film, .

Hereinafter, a solar power generation module having a heat generating function according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6, a solar photovoltaic module according to an embodiment of the present invention includes a solar photovoltaic board 5, a frame unit, and a heat ray 7.

The solar photovoltaic plate 5 is formed in a rectangular plate shape and has a battery cell which is usually irradiated with sunlight to produce electricity and a battery cell which is installed on each of upper and lower portions of the battery cell to absorb a shock, And a reinforcing glass provided on the upper portion of the upper protective sheet are stacked.

The frame unit is coupled to the edge of the solar photovoltaic plate (5) and serves to support the solar photovoltaic plate (5).

The frame unit has a rectangular shape surrounding the edge of the solar light support plate 5.

The frame unit includes a horizontal frame 20 coupled to the front and rear sides of the solar photovoltaic plate 5, a vertical frame 10 coupled to the left and right sides of the solar photovoltaic board 5, (40) which is coupled to the transverse frame (20) on one side and to the vertical frame (10) on the other side for interconnecting the transducers (10).

The frame unit applied to the present invention is made of an aluminum material, and four frames located on the front, rear, left, and right sides of the solar photovoltaic plate are coupled to each other longitudinally and laterally by the connector 40.

The four frames are divided into two horizontal frames 20 and two vertical frames 10. The transverse frame 20 and the vertical frame 10 are coupled to each other by the connector 40 with both ends thereof abutted against each other. For this purpose, the transverse frame 20 and the transverse frame 10 are cut and formed so that both ends of the transverse frame 20 and the transverse frame 10 form an inclination angle of 45 °. The horizontal frame 20 and the vertical frame 10 are opposed to each other at right angles.

Since the horizontal frame 20 and the vertical frame 10 have the same structure except for the length, the detailed description of the vertical frame 20 is omitted.

The transverse frame 20 includes a body 21 coupled to the solar photovoltaic plate 5 and having a hollow portion 23 formed therein and a cover 3 detachably coupled to the outer surface of the body 21 do.

The body 21 has an insertion rail 30 formed to protrude from the inside of the hollow portion 23 to form an insertion groove into which the connector 40 is inserted and an insertion rail 30 formed on the upper portion of the hollow portion 23, The insertion slot 25 is formed to be long along the longitudinal direction of the body 21 so that the edge of the body 21 can be inserted into the insertion slot 25 and the partition wall 27, An outward upper protrusion 31 protruding from the outer surface of the body 21 and formed with the first stopping protrusion 32 downwardly, And an outward lower protrusion 33 spaced downward from the outward upper protrusion 31 and protruding from the outer surface of the body 21 and having a second locking protrusion 34 formed upward.

The cover 3 has a plate-like base plate 35 which is coupled to the outer surface of the body 21 and seals the mounting passage 29, and a base plate 35 which protrudes toward the body 21 from the inner surface of the base plate 35 An inwardly facing upper projection 36 formed on the upper side of the base plate 35 so as to be engaged with the first engagement protrusion 32, And an inward lower protrusion 38 protruding in the direction of the body 21 and formed with a second engaging protrusion 39 which is engaged with the second engaging protrusion 34 downward.

Since the cover 3 is detachably attached to the body 21, it is very easy to mount, inspect and replace the heat ray 7.

The outward upper protrusions 31 and the outward lower protrusions 33 are formed so as to extend from the mounting passage 29 to the outside of the body 21 through the outward upper protrusions 31 and the outward lower protrusions 33 And the body 21 are formed with the inlet 1 and the outlet 2 through which the heat ray 7 can pass. The inlet (1) and the outlet (2) are formed as through holes. The inlet (1) and the outlet (2) are formed adjacent to each other.

The connector 40 is composed of a first insertion port 41 and a second insertion port 45. The first insertion port 41 and the second insertion port 45 are connected at right angles.

The first insertion port 41 is inserted into the insertion groove 8 formed in the body of the transverse frame 20 and is engaged with the transverse frame 20. The second insertion port 45 is inserted into the insertion groove in the body of the vertical frame 10 and is engaged with the vertical frame.

The first insertion port 41 is formed in a plate shape having a predetermined thickness, and a plurality of protrusions 43 are formed on the inner side surface of the first insertion opening 41. The thickness of the first insertion opening 41 is formed to be slightly smaller than the width of the insertion groove 8.

The projecting portion 43 is formed to be inclined. In other words, the first insertion opening 41 is inclined in a direction in which the first insertion opening 41 is inserted, thereby facilitating insertion into the insertion groove 8 and preventing the inserted first insertion opening 41 from being easily detached from the insertion groove 8 . The first insertion port 41 is forcedly inserted into the insertion groove 8 by the projecting portions 43 when the first insertion port 41 is inserted into the insertion groove 8. In this case, the end portions of the respective projecting portions 43 are deformed by the pressing force and inserted into the insertion groove 8 to maintain airtightness after insertion, and at the same time, increase the bonding force.

Since the second insertion port 45 has the same structure as the first insertion port 41, detailed description is omitted.

The heat ray 7 is installed inside the horizontal frame 20 and the vertical frame 10. The heat ray 7 is drawn into the inside of the transverse frame 20 through the inlet 1 formed in any one of the transverse frames 20. The hot wire 7 drawn into the horizontal frame 20 is a vertical frame 10 adjacent to the mounting passage 29. The vertical frame 10 sequentially passes through the horizontal frame 20 and the vertical frame 10, 20). And is drawn out to the outside of the horizontal frame (20) through the outlet (2). Fig. 1 shows a state of the heat line provided along the periphery of the solar photovoltaic plate in a dotted line.

A conventional nickel chromium wire can be applied to the heat wire 7. Further, a form in which a plurality of strands of carbon fibers are bundled by the heat ray 7 can be used. The hot wire may be coated with a material having insulation and heat resistance.

The hot wire 7 is electrically connected to a power source. The supply of power to the hot wire 7 can be electronically controlled. For example, when the snow accumulates on the PV module, the controller can apply power to the hot wire by a sensor that detects the snow. Further, it is possible to supply or cut off power to the hot wire by the operation of the operator.

When power is applied to the hot wire, the frame unit generates heat, so that the heat accumulated in the upper layer of the solar battery plate 5 is transferred to melt the snow accumulated on the solar battery plate 5.

The body 21 of the horizontal frame 20 is coupled to the front and rear sides of the rectangular photovoltaic plate 5 respectively and the bodies of the vertical frame 10 are respectively coupled to the right and left sides. The first insertion port 41 of the connector 40 is inserted into the insertion groove 8 formed in the body of the horizontal frame 20 and the second insertion port 45 is inserted into the body of the vertical frame 10 Into the groove. Then, the first insertion port 41 and the body 21 of the transverse frame are fixed using the screw 100, and the body of the vertical frame and the second insertion opening 45 are fixed. Then, the heat ray 7 is installed along the installation passage 29 formed on each body and the cover 35 is coupled to the body 21 to assemble the solar power generation module.

The cover of the horizontal frame located in the direction facing each other is first separated from the body 21 in order to couple the two solar power generation modules 120 to each other. Then, the frame coupling means 130 is coupled to the body 21 of any one of the solar modules 120. One edge of the upper plate 131 is inserted into the mounting passage 29 formed on the upper side of the body 21. One side edge of the lower plate 137 is inserted into the coupling passage 140 formed on the lower side of the body 21. Next, the other side edge of the upper plate 131 and the other side edge of the lower plate 137 are inserted into the mounting passages formed in the body 21 of the adjacent horizontal frame and the coupling passages, respectively.

In the illustrated example, the coupling between the horizontal frames is described by using the frame coupling means, but it is needless to say that the coupling between the vertical frames is also possible.

In another example of the present invention, as shown in FIG. 9, coupling between frame units in the vertical direction is possible.

The bottom plate 150 is engaged with the body 21 of the horizontal frame or the vertical frame located below. That is, the lower plate 150 is inserted and coupled to the mounting passage 29 formed in the adjacent body 21 at the lower side. At this time, the latching jaw 157 is hooked on the end of the outward upper protrusion 31 of the body.

The two bodies 21 are coupled up and down, and then the cover 35 is coupled to the upper body 21.
