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...

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...

Why are solar silicon wafers blue? To be precise, the solar cells are blue, and they are polycrystalline silicon solar cells, while monocrystalline silicon solar cells are generally black. Why is it blue or black, because that color is the effect of Anti-reflected Coating. Solar panels mainly absorb photons near the green wavelength in visible light, and the solar panel is blue, which means that i...

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...

Photovoltaic power plants can be divided into centralized power plants and distributed power plants. Centralized power plants are generally built in Northwest China. Distributed power plants are relatively scattered, mainly including household photovoltaics and industrial and commercial photovoltaics. So, what is the difference between household photovoltaics and industrial and commercial photovol...
