Solar photovoltaic power generation is the process of directly converting light energy into electrical energy by using the photovoltaic effect generated by the semiconductor interface. The DC power generated by the generator is converted into AC power through the inverter, boosted by the step-up transformer station and then sent to the power grid, and the power is transmitted to the power consumer...

HJT heterojunction cells subvert the traditional cell structure, and have the advantages of high conversion efficiency, simple manufacturing process, thin silicon wafer application, low temperature coefficient, no light-induced attenuation and potential attenuation, and double-sided power generation. There is an advantage in conversion efficiency that significantly exceeds PERC. The output efficie...

The grid-connected photovoltaic power system can convert the direct current output by the solar cell array into alternating current with the same amplitude, frequency and phase as the grid voltage, and realize the connection with the grid and transmit electric energy to the grid. The flexibility of this power generation system lies in that when the sunshine is strong, the photovoltaic power genera...

The household distributed photovoltaic grid-connected power generation system is located near the user and is generally installed on the roof of the user, especially suitable for the roof of the villa. The generated energy is used locally and connected to the grid at a voltage level of 220V/380V. The household distributed photovoltaic power generation system is a new type of power generation and e...

Now many factories and rural roofs use solar panel systems, which are pollution-free and can greatly save electricity bills. So what are the advantages and disadvantages of installing photovoltaic power generation systems on factory and rural roofs? Next, I will introduce it to you. advantage: Small investment, can save electricity, can make money, can shade, can reduce emissions. Disadvantages: T...

Photovoltaic inverters can convert the variable DC voltage generated by photovoltaic solar panels into mains frequency AC inverters, which can be fed back to the commercial system or used for off-grid grids. The photovoltaic inverter is one of the important system balances in the photovoltaic array system, and it can be used with general AC power supply equipment. Let me introduce the basic techni...

The solar photovoltaic system is composed of solar cells, solar controllers, and storage batteries (groups). If the output power is AC 220V or 110V, a photovoltaic inverter is also required. In winter, the power demand is the most and the sunshine is the least at the same time, so the use and maintenance of solar photovoltaic power generation systems in winter should be more serious. This article ...

Household photovoltaic refers to civilian use. The photovoltaic panels are installed on the roofs of ordinary people (mainly the roofs of rural residents). After the installation is completed, the power station can be integrated into the national grid. So what are the operating modes of household photovoltaic power generation? Let's take a look at the following. 1. Dealer model Distributors can ge...
