Advantages
China is blessed with abundant solar energy resources, with a theoretical annual reserve of 1.7 billion tons of standard coal equivalent. This vast potential makes solar energy one of the most promising renewable energy sources in the country. Due to its large geographical span—over 5,000 kilometers from north to south and east to west—China enjoys diverse solar conditions across different regions. In most areas, the annual average daily solar radiation exceeds 4 kWh per square meter, while in Tibet, it can reach as high as 7 kWh per square meter. With more than 2,000 hours of annual sunshine, China's solar potential is comparable to that of the United States and far superior to Europe and Japan. This favorable condition provides a solid foundation for the rapid development of solar power in the country.
Development Path
Solar cell research in China began in 1958, and by 1959, the first practical solar cell was successfully developed. The photovoltaic (PV) power generation industry started in the 1970s, initially used for space applications. In March 1971, it was first applied to China’s second satellite. By 1973, solar cells were being used on the ground, and by 1979, monocrystalline silicon solar cells were being produced commercially. After the mid-1990s, the PV industry entered a phase of steady growth, with increasing production capacity each year. By the early 21st century, the industry had entered a new stage of rapid expansion, driven by both domestic demand and international opportunities.
China's photovoltaic industry has undergone two major transformations. The first occurred in the late 1980s, during a period of economic reform and opening up. At that time, several solar cell production lines were introduced, boosting China’s production capacity from just a few hundred kilowatts to 4.5 megawatts within six factories. Government and enterprise investments played a key role in this development. The second wave of growth after 2000 was influenced by global trends, government projects, and market demands. Initiatives such as the "Guangming Project" in 2002 and the "Power Transmission to Townships" project in 2006 helped promote the use of solar PV technology, accelerating the industry’s expansion.
By the end of 2007, China’s cumulative installed photovoltaic capacity reached 100 MW, with over 50 companies producing solar cells. The total production capacity exceeded 2,900 MW, and annual output reached 1,188 MW. This made China one of the top producers in the world, surpassing Japan and Europe. A complete industrial chain had been established, from raw material production to system installation. Notably, polysilicon production saw significant progress, breaking through the 1,000-ton threshold and overcoming critical bottlenecks in the supply chain. However, the fast-paced growth also brought challenges, including overinvestment, intense competition, and a lack of innovation.
In June 2009, a joint venture between China Guangdong Nuclear Power Development Co., Ltd., Jiangsu Best Solar Technology Co., Ltd., and Belgian Enfinity Co., Ltd. won the bid for China’s first large-scale photovoltaic demonstration project in Dunhuang, Gansu. The project, a 10 MW grid-connected plant, was priced at 1.0928 yuan per kWh. This marked an important milestone, setting a benchmark for future grid-connected projects and paving the way for national subsidy policies. It signaled a turning point in China’s solar energy strategy, laying the groundwork for broader adoption of photovoltaic technology across the country.
What are the installation characteristics of prefabricated T house?
The practicability of the prefabricated T house is still very good. It only needs to determine the design requirements, and the construction and construction of the house can be completed immediately, and the long-term use is also guaranteed. But you still need to pay attention to the basic characteristics when installing the house.
Good fire and sound insulation
Now this kind of houses are built with sandwich panels. Commonly used are Eps Sandwich Panel, pu Sandwich Panel, Rock Wool Sandwich Panel, so it can achieve good fire prevention effect, and at the same time, it can also have good thermal insulation performance and sound insulation. effects etc. Therefore, the living comfort of such a house is guaranteed, and even if it is used for a long time, the sound insulation effect can be guaranteed without affecting daily life.
very easy to install
Because the prefabricated T-shaped houses are produced by standardized prefabrication in the factory, their overall construction and installation are also very convenient, and they can be disassembled at any time. Even if you don't continue to use the house, you can disassemble the steel plate at any time and store it in the warehouse. This can save construction time and also save a lot of labor costs.
Recyclable
All materials and components inside the house can be recycled for a long time, especially many steel plates are galvanized, even if they are used for ten or twenty years, there will be no rust and other problems, which can ensure their long-term use . The use of prefabricated T-shaped houses can effectively reduce construction waste, and can also play a good role in environmental protection.
easy to transport
The steel plates after dismantling of this kind of houses occupy a small area, are convenient to transport, and are light in weight, so construction and transportation are also very convenient. Most mobile homes are directly equipped with wheels. After the house is built, the daily transportation is very convenient, and the overall cost can also be saved.
strong security
The safety of the prefabricated T-shaped house is still very good, even if it encounters strong winds, strong earthquakes, etc., it can also guarantee its safe use. As long as the construction can be carried out according to our needs and the subsequent stable construction can be completed, the long-term use of such houses is also guaranteed.
