Household Photovoltaic Cell Follow-up Device

Abstract

The invention discloses a generating set and particularly relates to a household light following device of a photovoltaic cell. The household light following device of the photovoltaic cell is structurally characterized in that an output shaft of a motor used for controlling a cam group to rotate is connected with a shaft of the cam group; the cam group for driving a solar panel to rotate left and right by taking a rotating lever as the axis consists of two cams opposite in mounting direction; the two cams are coaxially connected; the lower end of the rotating lever capable of rotating around a support is fixedly arranged on the support; the solar panel capable of rotating around the rotating lever is arranged on the rotating lever; independent rotation of the single plate of the photovoltaic cell is realized by the rotating lever. The household light following device of the photovoltaic cell is simple to control, small in driving force and high in wind resistance; the upper end of a telescopic link is fixedly arranged at the upper part of the rotating lever, and the lower end of the telescopic link is fixedly arranged on the support; according to the household light following device of the photovoltaic cell, the angle of the solar panel can be adjusted according to the illumination condition, so that the solar panel is always at the best light energy receiving angle, and the light energy received quantity of the solar panel of the photovoltaic cell in unit time is increased; the household light following device of the photovoltaic cell is simple in structure and low in equipment input cost.

Description

technical field [0001] The invention relates to a power generation device, in particular to a household photovoltaic cell light-following device. Background technique [0002] Solar photovoltaic cells (PVCell), referred to as photovoltaic cells-SolarCell, use the photovoltaic effect to directly convert the sun's light energy into electrical energy. The photovoltaic effect, also known as the "photovoltaic effect", refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or a combination of a semiconductor and a metal. When sunlight irradiates the photovoltaic cell, the photons of sunlight excite electron-hole pairs in the cell, and the electrons and holes move to the two ends of the cell respectively. If the external path is formed, a current will be formed to generate electrical energy. The power generation efficiency of photovoltaic cells mainly depends on the amount of light energy received by the solar re...

Problems solved by technology

In order to improve the efficiency of photovoltaic cells in some foreign photovoltaic fields, more than a dozen photovoltaic panels are connected in series and parallel to perform light source tracking. Due to the large size, the investment in transmission, drive and control systems is more than 5 times higher than that of fixed installations.
