Sunward device for collecting rainwater to cool solar panel at high temperature

Abstract

The invention discloses a sunward device for collecting rainwater and cooling a solar panel at high temperature. The sunward device comprises a bearing box body, wherein a placement cavity is arrangedin the bearing box body, and four fixed tables are symmetrically and fixedly arranged on the inner wall of the lower side of the placement cavity along the front, back, left and right directions. Anauxiliary solar panel is used to measure the position of the Sun, solar radiation energy is utilized to the maximum extent while it is guaranteed that the main solar panel directly faces the sun, thedevice is more environmentally friendly compared with a sensor, in addition, the device can automatically collect rainwater in rainy days, and the collected rainwater is used for cooling and cleaningthe surface of the main solar panel when the air temperature is high; reduction of power storage efficiency of the solar panel due to over-high temperature is avoided, the actual working performance of the solar panel is greatly improved, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the field of solar panels, in particular to a sun facing device for collecting rainwater and cooling solar panels at high temperature. Background technique [0002] Solar cell, also known as "solar chip" or "photovoltaic cell", is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is the core part of the solar power generation system and the most important part of the solar power generation system. [0003] If solar panels want to achieve the highest power generation efficiency, they must first ensure that the solar panels are directly irradiated with the sun. However, the position of the sun in the sky changes all the time, and the fixed solar panels are very unstable in receiving solar radiation. The existing sun-facing solar devices It is mainly solved by sensors and motors, and the cost is too high. In addition, the power generation efficiency of solar panels decreases with t...

[0003] If solar panels want to achieve the highest power generation efficiency, they must first ensure that the solar panels are directly irradiated with the sun. However, the position of the sun in the sky changes all the time, and the fixed solar panels are very unstable in receiving solar radiation. The existing sun-facing solar devices Mainly rely on sensors and motors to solve the problem, and the cost is too high. In addition, the power generation efficiency of solar panels decreases with the increase of temperature. Therefore, while ensuring that the solar panels receive more solar radiation, it is also necessary to ensure that the surface temperature of the solar panels is suitable
