What is the photovoltaic industry?

Photovoltaic is an industry related to new energy. Photovoltaic industry, referred to as PV, refers to the use of photovoltaic effect to make sunlight shine on silicon materials to generate current to directly generate electricity. The industrial chain formed by the application and development of silicon materials is called "photovoltaic industry", including the production of high-purity polysilicon raw materials, solar cell production, solar cell module production, and the manufacture of related production equipment.

Photovoltaic power generation:

Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. The key component of this technology is solar cells. After being connected in series and packaged for protection, solar cells can form a large-area solar cell module, which is then combined with power controllers and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by geographical location because the sun shines on the earth; photovoltaic systems are also safe and reliable, noise-free, low-pollution, can generate electricity and supply power locally without consuming fuel or setting up transmission lines, and have a short construction period.

How to install photovoltaic panels

1. When installing a photovoltaic panel array, you need to consider the installation azimuth and tilt angle. Avoid obstruction between panels.

2. Fix the bracket and place the photovoltaic panel on it.

3. Wiring distance. The wiring distance should be as short and even as possible. The wiring should be firm to prevent false connection or disconnection.

4. The battery terminals must be firm and not short-circuited. Pay attention to the polarity during installation to avoid explosion and fire.

5. During the wiring process of the controller, pay attention to prevent polarity reversal, short circuit, etc. Pay attention to the placement angle and avoid rainwater infiltration.

6. The installation location must be open, and there must be no tall buildings or other objects blocking the sunlight at the installation site.

Does photovoltaic power generation have radiation?

Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

The photoelectric effect is the phenomenon that light causes a potential difference between different parts of an uneven semiconductor or a semiconductor and a metal. It is first a process of converting photons (light waves) into electrons and light energy into electrical energy; secondly, it is a process of forming voltage.
