Problems solved by technology

However, the sunlight tracking performance of this patent is relatively poor, and the sunlight cannot be tracked very accurately. Although the cost is low, the performance is low, the cost performance is poor, and the wind resistance of the device is obviously low, so it cannot guarantee long-term operation.

Abstract

The invention discloses an automatic sun tracking photovoltaic power generation device which comprises a hydraulic transmission device, a sun tracking device and a timing controller. The timing controller controls the hydraulic transmission device to output power so as to control a sun tracking device to track sun light. The hydraulic transmission mode is adopted in the automatic sun tracking photovoltaic power generating device, high reduction ratio and low cost are ingenious combined; compared with an existing double-shaft tracking device, a speed reducer which is high in price is omitted, and the automatic sun tracking photovoltaic power generation device has the advantages of being low in power consumption, low in cost and easy to maintain, is good in stability and has wind resistance.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to an automatic solar tracking photovoltaic power generation device and a control method thereof. Background technique [0002] Since automatic tracking of the sun can significantly increase the power generation per unit area of ​​solar panels, there are currently many patents on photovoltaic power generation devices that automatically track the sun in my country, but the devices designed by existing patents either use complex deceleration mechanisms or are not stable enough. The windproof ability is poor, or the self-driving energy consumption is high. In short, the tracking devices covered by the existing patents are not cost-effective, so that they have not been widely adopted. [0003] The existing patent provides a solar automatic tracking device (patent number: 201220042671.0), which drives the change of the inclination angle of the solar panel through the chang...
