Embodiment Construction

[0047] In the maximum power point tracking (MPPT) technology generally applied to the solar cell system, it needs to measure the current and voltage through the current and voltage measuring device, and then calculate its power. But the measured current is the short-circuit current flowing through an inductor. Although the short-circuit current flowing through the inductor has a certain proportional relationship with the sun's sunlight intensity and the sun-tracking angle deviation, the value of the short-circuit current is also affected by the load and the DC-DC converter. The effect of the duty cycle of the transistor switching PWM varies. Therefore, the short-circuit current through the inductor measured in the general maximum power tracking technology cannot be used to track the angle of the sun (ie track the position of the sun).

[0048] However, in the solar tracking method and the solar tracking system device of the present invention, the short-circuit current (throug...

Abstract

The invention relates to a sun tracking method which can continuously track the position of the sun without additionally mounting a photosensor, calculating the formula of sun track and timely correcting a mechanical structure, and a sun tracking system device. The sun tracking method comprises the following steps: (A) changing the attitude of a solar cell device, continuously matching with the switching of a power component of a maximum power tracking control device, measuring and recording short-circuit current through a short-circuit current measuring device, directly measuring and recording the short-circuit current through the short-circuit current measuring device or measuring and recording output power through a power measuring device of the maximum power track control device; (B) operating the maximum value of the recorded short-circuit current or the output power; and (C) driving a motor driving device and adjusting the attitude of the solar cell device to that corresponding to the maximum value of the short-circuit current or the output power.

Description

technical field [0001] The present invention relates to a solar tracking method and a solar tracking system device, in particular to a solar tracking method that does not require additional installation of a light sensor, does not need to calculate the formula of the sun's trajectory, and does not need to regularly correct its mechanical structure, and does not need to be precisely installed initially. A solar tracking method and a solar tracking system device for continuously tracking the position of the sun. Background technique [0002] Currently, among known solar power generation systems, Concentrated Photovoltaic (CPV) systems can focus sunlight on solar cells through optical components, thereby reducing the area used by solar cells and reducing power generation costs. However, it also makes the concentrating solar power generation system very sensitive to the angle of incident light. The solar cell area of ​​the high-concentration system (concentration rate greater t...
