Solar thermal power generation is a new type of solar power generation. The solar power generation that we mentioned before generally refers to photovoltaic power generation. This is two different approaches. There are two ways of solar power generation: thermal power generation and photovoltaic power generation. The operating principle and the scope of use of solar power are quite different. Solar thermal power generation is also called focused solar thermal power generation. Unlike photovoltaic power generation, it uses various physical means to gather direct solar light and generate high-temperature and high-pressure steam. Steam drives a steam turbine to generate electricity. According to the different heat collection methods, it can be divided into solar trough thermal power generation, solar tower thermal power generation, and solar disk thermal power generation. The difference between solar thermal power generation and photovoltaic power generation 1. The principle and device of power generation are different. Thermal power generation is driven by a heat-collecting device to generate electricity from a steam turbine. It is a heat transfer method. The most important component is a heat collector or device. Photovoltaic power generation uses the photovoltaic effect of semiconductors to convert light energy directly into electrical energy. Solar panels, the basic components, are the means of electricity conversion. 2, the scope of use is not the same. The electricity generated by solar thermal power generation has a better match with traditional thermal power and hydropower and is suitable for large-scale development. In addition, thermal power generation is more suitable for areas with good lighting conditions due to higher lighting conditions. Photovoltaic power generation devices are relatively simple and require relatively low lighting. They are more suitable for miniaturization and are therefore more suitable for decentralized use. 3, in the specific application. Photovoltaic power generation has become industrialized, and the use of technology has become more mature and suitable for a wide range of applications. The thermal power generation is still mainly in the demonstration stage of scientific research, and the cost is also at a very high level. It takes time for large-scale application. Lawn fences make homes, cities, and places where we live more beautiful and beautiful. And has many bright colors.

Lawn fences are mainly divided into: PVC lawn fences, cement lawn fences. Its main purpose is to decorate courtyards and green spaces, garden paths, and urban avenues, with white and beautiful visual effects, to make homes, cities, and places where we live more beautiful and beautiful.
PVC Lawn Fence
Beautiful appearance: white, blue, red, green and other colors, bright colors, smooth surface.
Safety, environmental protection, harmless to people (animals): smooth surface, delicate hand feeling, bright colors, high strength, good toughness, using domestically produced first-class raw materials, even if the guardrail is not accidentally touched, it will not hurt people like steel or iron guardrail.
Anti-aging test: it will not fade, crack or embrittle at 30 ° C to 70 ° C, it can be up to 30 years.
Maintenance-free: no decay, no corrosion, no fading, no daily maintenance, no pollution to the environment.
Easy installation: The patented friction-type connection or proprietary connection accessories are used for installation, which is simple, fast and secure.
Concrete lawn fence
It is produced by using special additives such as high-quality cement, sand, and steel bars. It is suitable for residential areas, courtyards, and villas.
Its products have high strength, bending resistance, bending resistance, tensile resistance, frost resistance, and impact resistance.
It has a strong sense of art: smooth lines and exquisite shapes, blending western art with oriental charm.
Good decoration: it has a bright and clean appearance, bright colors, and a variety of varieties. It can be harmoniously unified with various styles of buildings and regional environments, making people feel refreshed and beautiful.
This fence has been tested by the National Building Materials Testing Center, and its appearance, dimensional deviation, compressive strength, ultimate bending strength, impact strength, and frost resistance are all qualified.
