[0001] DESCRIPTION [0002] WIRE COVER STRUCTURE OF SOLAR GENERATING APPARATUS [0003]

The present invention relates to a wire cover structure of a photovoltaic power generation apparatus, and more particularly, it is possible to easily install a wire cover frame on an upper module frame of a module frame without installing a separate duct for housing the wire, The present invention relates to a structure of a wire cover for a photovoltaic power generation apparatus, which can protect a wire from being exposed to a wire and protect a wire from being exposed to the outside, thereby simplifying the installation work of the solar power generation device.

Generally, a photovoltaic device means that solar light is condensed (heated) in a solar cell or a solar module to perform power generation.

In addition, the photovoltaic modules of the photovoltaic device are connected by connecting the solar cells longitudinally and laterally, and the electricity generated from the individual solar cells is collected at the same time in the module. Such a photovoltaic module is a kind of solar cell module, , And there are general type, window type, tracking type, hybrid type (a type that is combined with other clean energy generating means), and the like.

In addition, the principle of photovoltaic power generation using such a photovoltaic module is performed by the effect of photovoltaic power. When a photovoltaic cell having a pn junction with n-type doping on silicon crystal is irradiated with sunlight, Which is called the photovoltaic effect. Solar panels can be connected in series and parallel as desired to make the desired power. The system that is stored in the battery and used when necessary is called an individual solar power generation system or a stand-alone solar power generation system. It is said to be a grid-connected photovoltaic power generation system.

In particular, the DC power generated by the solar module of the solar power generation device is converted to the AC power through the inverter device, and then supplied to a power consumption device such as a lamp.

In addition, the structure of the solar module generates electricity from the cells on the front side, and the +, - two-stranded wires are connected through the rear junction box, and electricity is supplied through the wires. When installing, configure the serial and parallel connection between the modules so that the + or - wire connector of the module is installed by combining with the opposite polarity of the side module.

As shown in FIG. 1, the solar module 10 is a solar module integrated with a module frame 20 having a generally rectangular frame shape. And the electric wire 31 is connected to one side or both sides of the back surface (inner surface) for collecting electric power generated by the photovoltaic effect in the cell to the charging regulator and the battery A junction box 30 is provided.

The junction box 30 is usually installed on the back surface (inner surface) of the solar module 10 to connect the electric wires 31 in the field.

However, the structure of the solar cell module of the conventional photovoltaic power generation device is inconvenient because the electric wires are exposed to the outside, which is not dirty or aesthetically pleasing, and the electric wires are arranged neatly by adding a separate electric wire arranging means.

That is, since a plurality of photovoltaic modules of the photovoltaic device according to the related art are usually installed, the photovoltaic module has a very inconvenient construction environment in which the photovoltaic module must be electrically connected, A long time is required for the operation and the productivity is lowered.

In the above method, a separate duct 40 is cut through a separate operation (size cutting, hole machining, etc.), and a safety device (rubber cap, etc.) for protecting the cutting surface of the duct 40 is installed. Additional processes such as inserting and installing a duct are necessary.

However, as described above, the installation of the photovoltaic power generation apparatus using the duct 40 requires a long period of time for the direct and parallel electric construction of the photovoltaic module, and there is a problem that a large number of personnel must be input to the work.

In addition, there is a problem that the material cost of the photovoltaic power generation device is increased by processing and installing a separate duct.

In addition, the position of the duct installed on the inner surface of the solar module of the photovoltaic power generation device is installed so as to protrude downward in the lower portion of the junction box, thereby deteriorating the aesthetics and causing a safety accident while the operator hits the operation.

In order to replace the modules or electric wires when the maintenance of the solar modules is required, the ducts 40, which are elongated and extend across the inner surfaces of the plurality of solar modules 10, are separated from the module frame, There is a problem in that it is impossible to replace the solar module 10 and the electric wire 31 quickly.

Therefore, the development of a wire cover frame is needed to easily detach the module frame of the solar module and to protect the wire from the outside without being exposed to the outside.
