Description

Solar photovoltaic module

Technical Field

The invention relates to the technical field of solar photovoltaic modules, in particular to a solar photovoltaic module.

Background

The single solar cell cannot be directly used as a power supply. Several single batteries must be connected in series, parallel and tightly packaged into an assembly to be used as a power supply. Solar cell modules (also called solar panels) are the core part of and the most important part of a solar power generation system. The solar energy is converted into electric energy, or is sent to a storage battery for storage, or the load is pushed to work. The solar photovoltaic panel is a power generation device capable of generating direct current when exposed to sunlight, and is composed of thin solid photovoltaic cells made of semiconductor materials. Solar photovoltaic panels are an important component in solar power generation devices.

For positive and negative charges, the positive and negative charges in the PN junction area are separated, so that an external current field can be generated, and the current flows from the bottom end of the crystalline silicon wafer battery to the top end of the battery through negative current. This is the "photovoltaic effect". When a load is connected between the upper surface and the lower surface of the solar cell, a current flows through the load, and the solar cell generates a current; the more photons the solar cell absorbs, the more current is generated. The energy of the photons is determined by the wavelength, photons below the base energy cannot generate free electrons, one photon above the base energy will generate only one free electron, the excess energy will heat the cell and the effect of the loss of electrical energy will decrease the efficiency of the solar cell.

The existing solar photovoltaic panel is directly fixed on the support, the support is of a fixed structure, the solar photovoltaic panel can only be fixed according to the angle of the support, and due to the fact that the positions of the sun are different in sunrise and sunset, the solar photovoltaic panel is short in irradiation time, the solar energy conversion electric energy efficiency is low, and when hail weather is met, hail is directly crashed on the solar photovoltaic panel due to the fact that protection facilities are lacking, and damage to the photovoltaic panel is easy to cause.
