Solar power system with light-tracking sensor

Abstract

The invention provides a solar power system with a light-tracking sensor. A shading barrel is fixed on one side of a base, a convex lens of a power generation assembly is fixed on the upper end of the shading barrel, the light-tracking sensor is arranged on the inner lower part of the shading barrel, a support column is fixed on the other side of the base, a stepping motor and a solar panel are fixed on the upper end of the support column, and both a central control system and an energy storage system are fixed on the base. Through experiments, compared with the efficiency of a fixed photovoltaic power generation device, the efficiency of the system can be increased by about 30%. Compared with the efficiency of a continuous light-tracking mode, the power generating efficiencies are not greatly different from one another, but a discrete light-tracking mode is adopted, so that the motor acts slightly, and the energy consumption and energy loss are correspondingly reduced. Compared with the light-tracking device which is installed on the solar panel, one light-tracking device is utilized to realize automatic light tracking of the solar panel within a certain scope, so that the load of the motor is reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to a solar power generation device with a light tracking sensor, belonging to the technical field of solar power generation devices. Background technique [0002] Photovoltaic power generation has a series of advantages such as stable performance, long equipment life, high reliability, and low maintenance. However, due to the characteristics of low solar energy density and large randomness, photovoltaic power generation systems generally require large investment and high cost. [0003] At present, the traditional solar power generation system mainly adopts fixed installation or simply uses software algorithm to realize light tracking. Fixed-installation products cannot adjust the attitude of the solar system according to changes in the sun's position, resulting in low solar energy collection and utilization, and high long-term investment costs. However, software tracking power generation equipment that only uses geographical loca...

Problems solved by technology

[0004] However, most of the few products that use sensor light tracking devices install light tracking devices on solar panels, that is, each solar panel needs to install a light tracking device, so the number of light tracking devices is large, which increases the cost.

At the same time, most of the existing light-following equipment adopts the continuous light-following method (that is, the sensor controls the solar panel to align with the sun in real time, which is actually unnecessary), which consumes a lot of energy and is easy to cause malfunction, which also increases the corresponding cost. cost
