Solar photovoltaic power generation method for multi-directional curved surface night light return

Abstract

The invention discloses a solar photovoltaic power generation method for multi-directional curved surface night light return, and belongs to the photovoltaic power generation field. According to the solar photovoltaic power generation method for multi-directional curved surface night light return, an absorption and reflection plate integrated with the solar panel, is arranged, so that the effect of continuously generating power in the daytime and at night can be achieved; during daytime, one absorbing and reflecting plate is always kept flush with the solar panel to absorb sunlight, and the light absorption amount of the multi-curved-surface bidirectional plate is ensured; continuous power generation of the whole solar panel at night is effectively ensured; one absorbing and reflecting plate is always used for reflecting sunlight; therefore, the solar panel can absorb more sunlight in the daytime; and when the multi-curved-surface bidirectional plate releases light at night, the multi-curved-surface bidirectional plate can be close to the solar panel and light can completely cover the solar panel after rotating along with the absorption and reflection plate due to the fact that theabsorption and reflection plate where the multi-curved-surface bidirectional plate is located is integrated with the solar panel, and therefore the overall power generation efficiency of the solar panel is remarkably improved.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, and more specifically relates to a solar photovoltaic power generation method for multi-directional curved surfaces returning light at night. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. A single solar cell cannot be directly used as a power source. As a power supply, several single solar cells must be connected in series and parallel and tightly packed into components. A solar panel (also called a solar cell module) is an assembly of multiple solar cells, which is the core part of a solar power generation system and the most important part of a solar power generation system. [0003] There are two ways of solar power generation, one is light-heat-electricity conversion, and the other is light-electricity direct conversion. One is: the light-...

AI Technical Summary

Problems solved by technology

[0004] The solar panel realizes the conversion of light to electricity by absorbing sunlight. In order to improve the absorption rate of sunlight, the solar panel has realized the sunlight tracking in the prior art, that is, the light-receiving surface of the solar panel can always be illuminated by the sun during the day. The light is irradiated, but when the solar panel converts light energy to generate electricity, due to the natural properties of sunlight, the power generation process of the solar panel stops at night due to the lack of light. The Chinese patent application number CN201410205058. Solar power station with long afterglow luminescent material luminescent panels to increase the amount of power generation” discloses the way that solar panels can also generate electricity, but the implementation method in this patent only describes the storage of light energy during the day and the power generation through the stored light energy at night. However, in order to avoid that the storage of light energy during the day does not affect the absorption of light by the solar panel, a certain distance is required when setting the two, resulting in the release of light at night, due to the problem of distance, the solar panel at night cannot The absorption rate is low, that is, the power generation efficiency of solar panels is low at night
