Producing method of solar energy collecting plate

Abstract

The present invention discloses a solar energy collection plate. Several Fresnel lenses capable of collecting solar energy are arranged on the described solar energy collection plate. Every Fresnel lens is corresponded to a solar cell. The energies collected by all the solar cells can be converged together, so that it only has need of increasing number of Fresnel lenses, the large energy can be obtained.

Description

【Technical field】 [0001] The invention relates to a solar collection board, in particular to a manufacturing method of a solar collection board. 【Background technique】 [0002] Solar energy is the energy produced by the continuous nuclear fusion reaction process inside the sun. Although the energy radiated by the sun to the earth's atmosphere is only 1 / 2.2 billion of its total radiated energy (about 3.75×1026W), it is as high as 173,000TW, which means that the energy irradiated by the sun on the earth every second is equivalent to 5 million tons of coal. The wind energy, water energy, ocean temperature difference energy, wave energy, biomass energy and part of tidal energy on the earth all come from the sun; even the fossil fuels on the earth (such as coal, oil, natural gas, etc.) are fundamentally ancient. The solar energy that has been stored since then, so the scope of the generalized solar energy is very large, while the narrowly defined solar energy is limited to the ...

AI Technical Summary

Problems solved by technology

[0005] At present, solar energy has been applied in many industries. Generally, a single lens is used to collect solar energy. Because a single lens has certain restrictions on energy collection, the collected energy is limited and cannot meet people's large demand for energy. , especially power generation and other industries that require a lot of energy to carry out can not use solar energy at all, so that people's use of solar energy has been greatly restricted

In addition, the focal length of the lens generally used is long, and the lens is always horizontal, so the energy is not concentrated when the sun’s insolation is large, so the energy collected by the solar cell is very limited; a certain area of ​​the solar cell collects The energy is limited; a single-layer acquisition lens is basically used, and the focal length is not short enough when the area is certain, and it takes up a lot of space
