Embodiment 1

[0021] like figure 1 As shown, this embodiment includes seven spherical solar cell panels 5 , and the seven spherical solar cell panels are connected in series to form a spherical solar cell group 1 . The seven spherical solar panels 5 are all placed on a 3×2 meter base plate, and on the base plate, the seven spherical solar panels 5 are arranged in three rows according to the longitude. Two solar panels 5. The electric energy output by the spherical solar cell group 1 is connected to the inverter 4 through the positive and negative terminals. After the conversion from DC to AC DC / AC in the inverter 4, the AC power is finally output for other electrical equipment. . The above-mentioned spherical solar cell panel 5 is composed of a plastic sphere in the center and a cell panel covering the surface of the plastic sphere. In addition, the spherical solar cell panel is a sphere with the same radius, and a ball rod 6 is arranged below the spherical solar cell panel. The rod 6 ad...

Embodiment 2

[0034] like figure 1 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, after seven spherical solar cell panels 5 are connected in series to form a spherical solar cell group 1, they are first connected to a charge controller 2, and the charge controller 2 Then it is connected with the storage battery pack 3 , and the storage battery pack 3 is connected with the inverter 4 .

[0035] A solar cell is a device that responds to light and converts light energy into electricity. P-type crystalline silicon can be doped with phosphorus to obtain N-type silicon, forming a P-N junction. When the light shines on the surface of the solar cell, some photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons, which accumulate on both sides of the P-N junction to form a potential difference. When the external circuit is connected , under t...

Embodiment 3

[0039] In this embodiment, six spherical solar cell panels are used, and the six spherical solar cell panels are connected in series to form a spherical solar cell group. The six spherical solar panels are also placed on a 3×2 meter base plate, and on the base plate, the six spherical solar panels are arranged in two rows in longitude and three in latitude. The electric energy output by the spherical solar battery pack is connected to the inverter through the positive and negative terminals. After the conversion of DC to AC DC / AC in the inverter, the final AC output is used by other electrical equipment. The above-mentioned spherical solar panel is composed of a plastic sphere in the center and a battery panel covering the surface of the plastic sphere. In addition, the spherical solar panel is a sphere with the same radius, and a club is provided under the spherical solar panel. The club adopts A flat rod is used to support the whole sphere, and the spherical solar panel is c...

Abstract

The invention discloses a spherical solar lighting system which comprises at least one solar panel connected with an inverter, and the solar panels are all spherical solar panels which are connected in series to form a spherical solar battery array. The spherical solar lighting system comprises the spherical solar panels, a charge controller, a storage battery set, an inverter AC output, and the like and is a device for improving the solar generation convert ratio. The spherical solar lighting system learns the advantages of the prior solar panels and overcomes the defects of angle consideringand fixed lighting of sloping solar panels and lean-to solar panels. The spherical solar lighting system uses the spherical solar panels, though a sun angle tracking device is not used, the sphericalstructure of the spherical solar lighting system can guarantee that a half sphere is always under the irradiation of sunshine at any time under the condition that the sunshine exists, thus the stability of absorbing solar energy can be guaranteed.

Description

technical field [0001] The invention relates to a solar lighting system, in particular to a solar lighting system whose generator adopts a spherical shape. Background technique [0002] As the most potential energy source in the 21st century, the development potential of the solar energy industry is huge. The solar energy industry is an emerging sunrise industry, coupled with a favorable policy environment and the characteristics of the industry itself, the solar cell industry has high investment value and development potential. Solar panels are a hot spot of domestic research in recent years. From data analysis, popular applications are mainly divided into two categories in terms of appearance: inclined solar panels, side-slope solar panels, and arched and ridge-shaped solar panels. It is based on the current low conversion rate of solar panels and huge space occupation. Foreign research on solar cells mainly includes the United States and Japan. [0003] The units engag...
