New energy parts case
I. Introduction. With the intensification of the energy crisis, the new energy industry has become a strategic industry for the development of various countries.
As an important part of new energy equipment, new energy parts play a key role in the new energy industry chain.
This article will take the case of new energy parts as the theme, the development status, application fields and future development trends of new energy parts.
Second, the development status of new energy parts.
1.Solar modules.
Solar cell modules are the part of the solar photovoltaic power generation system, and their main role is to convert solar energy into direct current energy.
At present, there are three main types of solar cell modules: monocrystalline silicon, polycrystalline silicon and thin-film solar cells.
Among them, monocrystalline silicon solar cell modules have the advantages of high efficiency and long life, but the cost is high;Polycrystalline silicon solar modules are less costly, but less efficient;Thin-film solar modules are flexible, thin and lightweight, and are suitable for some special applications.
2.Wind turbines.
Wind turbines are important equipment that converts wind energy into electrical energy, and its main components include wind turbines, generators, and control systems.
At present, wind turbines are mainly divided into two types: horizontal axis wind turbines and vertical axis wind turbines.
Horizontal axis wind turbines have the advantages of high efficiency and strong adaptability, and are currently the mainstream wind turbinesVertical axis wind turbines have the characteristics of simple structure and low noise, and are suitable for noise-sensitive areas such as cities.
3.Energy storage devices.
Energy storage device is a key equipment to solve the fluctuation and intermittency of new energy power, and its main role is to store electric energy for emergency use.
At present, common energy storage devices mainly include batteries, supercapacitors and compressed air energy storage devices.
Battery energy storage device has the advantages of high energy density and long cycle life, and is currently the most widely used energy storage deviceThe supercapacitor energy storage device has the characteristics of fast charging and discharging, long life, etc., and is suitable for short-term high-power application scenariosCompressed air energy storage devices have the advantages of high energy storage density and wide application range.
Third, the application field of new energy parts.
1.Architectural field.
The application of new energy parts in the field of construction is mainly reflected in the utilization of solar photovoltaic power generation system and the utilization of wind power generation system.
Solar modules can be installed on the roof or exterior wall of a building to convert solar energy into electricity to provide electricity to the building;Wind turbines can be installed at or near a building to generate electricity from the wind and provide electricity to the building.
