Solar energy absorption device and method

Abstract

The invention discloses a solar energy absorption device and method and belongs to the field of solar energy utilization. The solar energy absorption device comprises a solar panel, a supporting body, a rotary support and a reflection plate. The supporting body comprises a stand column and a supporting plate. The supporting plate is connected with the top of the stand column, and the solar panel is arranged on the supporting plate. One end of the rotary support is connected with the stand column, and the other end of the rotary support is connected with the reflection plate. The rotary support rotates around the stand column. The invention further provides the method. The method comprises the steps that an hour angle is obtained; a solar declination angle is obtained; the solar altitude is calculated according to the obtained hour angle, the solar declination angle and the geographic latitude, and the pitching angle is adjusted through the reflection plate according to the solar altitude obtained through calculation; according to the obtained hour angle and the solar altitude, the rotation angle of a shadow is calculated so that the angle of the rotary support can be adjusted. According to the sunlight illumination direction, the reflection plate reflects sunlight to the solar panel, and the solar energy absorption efficiency of the solar panel is improved.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a solar energy absorbing device and method. Background technique [0002] As environmental pollution and energy shortage become more and more obvious, the use of solar energy has attracted more and more attention. Solar panel is currently a relatively common device for utilizing solar energy. Its principle is to directly or indirectly convert solar radiation energy through photoelectric effect or photochemical effect by absorbing sunlight. Solar panels are typically mounted on rigid supports or on the roof of a building. Due to the earth's rotation and revolution, the sun rises from east to west every day, the alternation of spring, summer, autumn and winter, and the weather, the intensity of sunlight received by solar energy is constantly changing, far from reaching the saturation value of solar panels, which affects the absorption of solar panels. The efficiency of sol...
