Solar Panel

China Solar Panel Manufacturer

Shenzhen Houny Battery Co., Ltd., , as a china solar panel manufacturer, founded in 2005, is a high-tech enterprise integrating R&D, production and sale of solar panel.here, we will introduce you solar panel of we product.

A solar cell panel, solar electric panel, photo-voltaic (PV) module or just solar panel is an assembly of photo-voltaic cells mounted in a framework for installation. Solar panels use sunlight as a source of energy to generate direct current electricity. A collection of PV modules is called a PV panel, and a system of PV panels is called an array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.

What is a solar panel? 

Photovoltaic power generation refers to a method of generating electricity that uses solar radiation to directly convert into electrical energy. Photovoltaic power generation is the mainstream of solar power generation today. Therefore, solar power generation is often referred to as photovoltaic power generation.

Photovoltaic distributed power generation is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principles of nearby power generation, nearby grid connection, nearby conversion, and nearby use, which can not only effectively increase the power generation of photovoltaic power plants of the same scale. At the same time, it also effectively solves the problem of power loss in boosting and long-distance transportation. However, distributed power generation also puts forward strict requirements on how to maximize solar power generation and how to ensure grid safety. In this process, the functionality and stability of photovoltaic inverters are also extremely critical. Distributed power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, and makes full use of local solar resources to replace and reduce fossil energy consumption.

The difference between monocrystalline and polycrystalline solar panels

The difference between monocrystalline and polycrystalline solar panels: the background color of the monocrystalline silicon surface is black or light blue, while the background color of the polycrystalline silicon surface is mostly blue or black.

The difference between monocrystalline and polycrystalline solar photovoltaic panels: Compared with polycrystalline panels with opposite power, the area of polycrystalline panels is slightly larger than that of monocrystalline panels.

Advantages of monocrystalline polycrystalline solar photovoltaic panels: Polycrystalline silicon panels can receive light from multiple directions and have good directivity. In practical tests, assuming that one hand blocks the sun's rays and leaves a dark shadow on the surface of the solar panel, the current reduction in the polycrystalline panel is smaller than that of the single-crystalline panel. This is the advantage of polycrystalline panels. And his price is definitely lower

How to use solar panel

The current generated by the generator panel is direct current, with positive and negative poles. When charging, the positive and negative poles of the generator panel can be connected to the positive and negative poles of the battery. There is a backflow preventer in the junction box for polycrystalline and single-crystalline boards. After the battery is fully charged, the battery charging will automatically stop. It has the function of preventing overcharge. Monocrystalline polycrystalline solar photovoltaic panels

The historical origin of solar panel

In 1839, when 19-year-old Becquerel, France, did a physical experiment, he discovered that the current would increase when two metal electrodes in a conductive liquid were irradiated with light, and thus discovered the "photovoltaic effect." In 1930, Yin Ge first proposed using the "photovoltaic effect" to make solar cells, turning solar energy into electricity.

In 1932, Audubot and Stola made a "cadmium sulfide" solar cell.

In 1941, Audu discovered the photovoltaic effect on silicon.

In May 1954, Chapin, Fuller and Pilsson of Bell Laboratories of the United States developed a monocrystalline silicon solar cell with an efficiency of 6%. This is a solar cell with practical value in the world. In the same year, Wick discovered nickel arsenide for the first time. It has a photovoltaic effect, and a nickel sulfide film is deposited on the glass to make a solar cell. The practical photovoltaic power generation technology that converts sunlight into electrical energy was born and developed.

Solar panel system components

The photovoltaic power generation system consists of a photovoltaic array (a photovoltaic array is composed of photovoltaic modules in series and parallel), a controller, a battery pack, and a DC/AC inverter. The core component of the photovoltaic power generation system is the photovoltaic module, and the photovoltaic module is in turn It is made of photovoltaic cells in series, parallel and packaged. It directly converts the sun’s light energy into electrical energy. The electricity generated by photovoltaic modules is converted into direct current. From one point of view, the electricity generated by the photovoltaic system can be used immediately, or it can be stored with energy storage devices such as batteries, and released for use at any time as needed.
