Abstract

The invention relates to a tracking method of a solar power generating apparatus. The power generating apparatus has a dual-glass unit having a cavity; and a plurality of vertical arc light-transmitting projections are successively arranged at the front-side glass and form vertical-bar-shaped convex lenses capable of realizing light condensation. Supports with arc tracks are arranged in the cavity, wherein the supports and the convex lenses correspond to each other one by one; mounting seats that can slide along the arc tracks are installed at the supports; and solar cells are fixed at the front surfaces of the mounting seats. According to the tracking method, within the effective collection period of the solar energy, a drive mechanism is used for driving the mounting seats to slide along the arc tracks, so that the incident sun light is gathered together by the convex lenses and can irradiate the solar cells in a basic covering mode. Therefore, the amount of the used solar cells can be substantially reduced; the production cost is saved; and the utilization rate of the solar energy is improved. Because the incident light is gathered when passing through the glass, the light shielding by guano can be reduced and no non-light region is formed at the cell, thereby eliminating the heat island effect.

Description

technical field [0001] The invention relates to a tracking method for a solar power generation device. Background technique [0002] With the improvement of people's awareness of environmental protection, the demand for clean energy is increasing. Among the new clean energy researched by people, solar energy, as a clean energy that is not subject to geographical restrictions, has become the main direction of new energy development in the future. Solar cells are the main devices that people use the sun's light energy to convert into electrical energy. [0003] At present, solar cells are all processed with silicon as the base material. Since silicon is easily oxidized in the air, the solar cells need to be packaged. Traditionally, two pieces of glass are used to bond the front and back of the solar cell for packaging. At present, the mainstream solar cell packaging uses fluorine-containing resin and other transparent resins instead of glass as the packaging material. Taking...
