In general, crystals, tourmaline, Rochelle salt, etc. have been used as a piezoelectric element early on, and artificial crystals such as barium titanate, ammonium dihydrogen phosphate, and ethylene diamine tartrate developed in recent years also have excellent piezoelectricity.

Piezoelectric is a phenomenon in which a certain type of crystal plate is applied in a certain direction and the charge is proportional to the external force on both sides of the plate. Jacques Curie and Pierre Curie of 1880 Brothers first discovered. Since the piezoelectric power on a single sheet is weak, it is known that the amount of the piezoelectric material increases greatly when the sheets are overlapped with each other.

It was also found that there is an inherent vibration in the crystal plate and that when the elastic vibration and the electric vibration coincide, the vibration is combined with the piezoelectric force to generate a stronger vibration. And various inventions using these phenomena have followed.

Accordingly, crystals and barium titanate are widely used as piezoelectric elements in Rochelle salts, speakers of telephones and radios, ultrasonic detectors, crystal oscillators, broadcasting devices, and telecommunication circuits for pickup of microphones or electric shafts.

As is well known, the solar panel converts solar energy (light) into electrical energy using a solar cell composed of a semiconductor. When the module absorbs light, the basic principle is the optoelectronic effect that generates electrons from the surface to generate electricity.

Referring to the operation of the present invention configured in this way in more detail as follows.

First, during a sunny day, the solar panel 190 absorbs sunlight and converts it into electrical energy.

As described above, the solar cell panel converts solar energy (light) into electrical energy using a solar cell composed of a semiconductor. When the module absorbs light, electrons are generated on the surface to generate electricity. Shall be.

The electrical energy thus converted is controlled by the solar controller controller 210 to be charged in the battery 300 or supplied to each DC load or AC load and supplied to the load power.

On the other hand, when it is rainy or cloudy and windy day, the supply of light to the solar panel is not smooth, so it is not possible to generate enough electrical energy using sunlight, but in the present invention through the vibration using a film-type piezoelectric element) It can additionally generate electrical energy.

Here, as described above, the film-like piezoelectric element disposed on the surface of the solar cell panel converts the pressure applied to the surface, for example, the impact of raindrops and the vibration generated by the wind into electrical energy.

As described above, the present invention forms a piezoelectric element on a solar panel in the form of a thin thin film and forms and produces it with the installation of an elastic member on the solar panel, thereby making it difficult to receive the rainy season or other topographical and environmental requirements. In order to overcome the practical limitations in which it is difficult to make the most of solar energy efficiently, the vibration generated by the raindrops falling on the piezoelectric element in the form of thin transparent film is converted into electric energy to produce electricity as well as wind. It also produces electricity through vibration. This, by using a piezoelectric element mounted on the solar panel can be produced and stored simultaneously in the electrical energy generated through the raindrops and the electrical energy generated through the wind, the electrical energy generated by the sunlight through the solar panel.

Therefore, by forming a film-type piezoelectric element on the solar panel to produce electrical energy through the vibration, pressure, and wind of the raindrops, energy production is further produced by producing additional electrical energy not only in rainy weather but also in the presence of wind at all times.
