Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power generation device with a two-dimensional photovoltaic heliostat mechanism. Background technique [0002] At present, the solar panels of solar power generation systems for communication equipment are all fixed installations, and their inclination angles and azimuth angles are fixed and will not change. Due to the earth's rotation and revolution around the sun, the sun's daily hour angle and seasonal declination angle change. Then the incident angle of solar light on the fixedly installed solar panels changes momentarily. Under the same solar radiation intensity and because of the different incident angles of sunlight, the amount of energy collected per unit area of ​​the solar panel is different. When the sun's rays are vertically projected onto the solar panel (incident angle θ=0°), the solar radiation energy received by the solar pan...

Problems solved by technology

[0005] This device can realize the tracking and positioning of the sun more accurately, but the mechanical structure is relatively complicated. Not only that, because the motor needs to be stopped suddenly after the incident angle of sunlight is positioned, so the solar panel still has a tendency to move, and it is easy to cause the motor to Wear and tear, so it lacks a braking system, and because sunlight has a certain amount of heat, it is easy to heat up the solar panel after a long time of sunlight, which will reduce the efficiency of photovoltaic power generation, and there is no protection against sunlight in the existing photovoltaic power generation technology. Waste heat is recycled, wasting the waste heat of sunlight
