Problems solved by technology

The photovoltaic conversion rate of existing solar panels has not been high. Only under strong light can the photovoltaic conversion be relatively high, while the photovoltaic conversion rate is low, which directly affects the conversion of solar energy, especially in cloudy days. The efficiency is lower. On the one hand, the main reason is that most of the sunlight irradiated on the solar panel is directly reflected back into the air, resulting in less solar energy actually used by the solar panel.

Embodiment 1

[0016] like figure 1 As shown, a solar panel includes a solar panel 1, a chip 2, a PVC panel 3 and a circuit board 4 from outside to inside, the chip 2 is connected to the circuit board 4, and the inner surface of the solar panel 1 is curved and wavy , the crests and troughs on the inner surface of the solar panel 1 are all arc surfaces, and the outer surface of the solar panel 1 is distributed with at least one or more arc surfaces extending along the length direction of the solar panel, and the arc surfaces are covered with layers corresponding to their shapes and sizes. metal reflective layer.

[0017] Among them, the cross-section of the arc surface is an arc, and the range of the central angle θ of the arc is 0 0 0 .

[0018] The cross-sections of the arc-curved surfaces are uniform in size and distributed continuously without intervals along the lateral width direction of the solar panel 1 .

[0019] Of course, the cross-sectional size of the arc curved surface can al...

Embodiment 2

[0022] like figure 2 As shown, this embodiment is basically similar in structure and principle to the above-mentioned embodiment 1, the difference is that the cross section of the arc surface is a "convex" curve.

[0023] It can be seen from the above description that the technical solution has a simple structure and can reflect sunlight back to the solar panel to improve photovoltaic conversion efficiency.

Abstract

The invention provides a solar panel. The solar panel provided by the invention is characterized by sequentially comprising a solar energy panel, a chip, a PVC panel and a circuit board from outside to inside, wherein the chip is connected with the circuit board, the inner surface of the solar energy panel is shaped like cambered-surface waves, the peaks and the troughs of the inner surface of the solar energy panel are cambered surfaces, at least one or more circular arc curved surfaces extending along the length direction of the solar energy panel are distributed at the outer surface of the solar energy panel, and each circular arc curved surface is covered with a metal reflecting layer which corresponds to the circular arc curved surface in shape and size. According to the technical scheme, sunlight can be reflected back to the solar energy panel, and the photovoltaic conversion efficiency is improved.

Description

technical field [0001] The invention relates to a solar panel, in particular to a solar panel capable of reflecting sunlight irradiated on the solar panel. Background technique [0002] Solar energy is a clean and renewable new energy source, which is more and more favored by people and has a wide range of functions in people's life and work. One of them is to convert solar energy into electrical energy, and solar cells use solar energy to work. The working principle of a solar thermal power station is to use the concentrated sunlight to boil water until it turns into water vapor, which is then used to generate electricity. The photovoltaic conversion rate of existing solar panels has not been high. Only under strong light can the photovoltaic conversion be relatively high, while the photovoltaic conversion rate is low, which directly affects the conversion of solar energy, especially in cloudy days. The efficiency is lower. On the one hand, the main reason is that most of ...
