Control Method and Device for Quasi-Uniaxial Sun Chase of Solar Panels

Abstract

The present invention relates to a control method and device for quasi-uniaxial sun chase of solar panels. The present method uses uniaxial driving to perform real-time tracking of the zodiacal longitude position of solar “daily periodic change”, then abiding by seasonal “annual periodic change” to perform tracking fine tuning of less 0.25 degrees per day on celestial sphere declination. The present device includes a supporting unit with two corresponding holders on the end face, a frame body for solar panel installation configured between the said two holders, and a control mechanism including a setting unit as well as an enable unit connected to the frame body. Thereby, in addition to real-time correction to the corresponding position of the solar panel to Sun by setting the control mechanism to allow the solar panel to acquire higher incident solar energy. The present invention provides a simple device structure with lower operation power consumption.

Benefits of technology

[0010]Yet another objective of the present invention is to provide a simple device structure capable of consuming lesser operation power.

Problems solved by technology

The solar panel in a conventional solar energy generating system is generally installed at a fixed angle, and as it does not acquire vertical incident Sunlight, thus the utilization efficiency of incident energy from Sun can not be maximized causing the problem of low power generation amount.

Although such types of multi-axial Sun chase mechanisms usually increases the daily power generation amount of the solar panel, however the manufacturing cost of the multi-axial Sun chase mechanism is expensive.

Besides, the mechanism itself has to bear the heavy weight of the solar panel, and therefore to achieve the said objective of exact Sun chase, multi-axial driving mechanisms usually incur higher power consumption, which may perhaps exceed beyond the increased amount of power generation amount contributed by the precise Sun chase.
