"Chengdu made" photovoltaic power generation glass supply is in short supply. When will the home improvement come true?

Sichuan continues to be high temperature, and Chengdu Power Grid load has repeatedly reached high, and many enterprises and office buildings have opened the "power saving" model.

At this time, power generation glass and solar power generation have become the power supply method for many people.

It is not new to use solar power generation. As early as the 1970s, China's photovoltaic power generation industry had begun. After nearly 50 years of development, photovoltaic power generation was layout in Sichuan, Jiangsu, Hebei, Jiangxi and other places.

What is the current application of photovoltaic power generation in Sichuan? How far is family photovoltaic power generation? The reporter visited.

What is the application of photovoltaic power generation park?

The maximum power generation power generation is up to 5,000 degrees, accounting for about 20% of the electricity consumption in the park

At present, power generation glass is applied in Chengdu Chuankai Electric Industrial Park, Chengdu Shuangliu International Airport, Chengdu Smart Center and other applications. In China, Zhangjiakou Citizen Center, Shanghai Songjiang Robotics Industrial Park Building, and large factory buildings in Tongcheng Industrial Zone, Anhui have also been applied. What is its power generation effect?

On the afternoon of August 18th, Red Star reporters came to Tidist Electric Industrial Park in Shuangliu District. In the plant in the park, the reporter saw the power generation glass set on the top of the plant. The top of the entire plant is constructed in accordance with human shape and waves, and the roofs facing south are built with power generation glass.

"The total area is about 15,000 square meters, and a total of 6880 yuan is installed with a power generation glass with a length of 1.6 meters long and 1.2 meters wide. The peak period of power generation is 5555 degrees." The glass said that it can basically meet the electricity room, security monitoring and employee dormitory of the park.

According to Liu Shixu, when the park is operating normally, the electricity consumption is about 20,000 degrees to 30,000 degrees a day, and the daily power generation of the power generation glass accounts for 20%of the park's electricity consumption. According to estimates, the park's power generation glass can generate 1.4 million kWh a year. At the current electricity price, it can save about 800,000 yuan per year. "In addition to the daily supply of the park, the power generation glass can also be powered on the power grid when the power generation exceeds the power of the park. From June 15 last year to the end of the year, it has returned more than 7,000 yuan."

The reporter saw in the factory building that the area of ​​power generation glass was brighter, and the areas of ordinary roof were dim. "At the beginning of the construction, because of worrying about the light transmission of power generation glass, we also reserved the light transmittance area on the top of the plant. Now it seems obviously more worrying." Liu Shixu told reporters that the roof of the park is equipped with cadmium 碲 film film. Power generation components are suitable for weak light environment, and are still applicable in areas with short light time in Chengdu.

Supply

The annual output of 20 million square meters of power generation glass, still constantly coming to order for enterprises

Liu Shixu shared the detection data in the company's smart energy management system for reporters on the spot. From the data point of view, the cadmium cadmium film power generation glass began to generate electricity from 6:40 in the morning, and did not end the power generation until 7:30 pm. Even in the morning and evening sunlight, it can still generate a small amount of electricity.

It is understood that at present, the photovoltaic industry is mainly divided into two major technical camps: crystal silicon and film solar cells. Among them, cadmium cadmium film power generation glass is a widely used category of thin -film solar cells. Compared with other solar batteries, cadmium film power generation glass is lower than other solar batteries, and its conversion efficiency is higher than other types of solar cells such as crystal silicon and gallium arsenidium. At the same time, the weak light effect is good. It can be generated in the weak light environment. Therefore, for areas such as Chengdu's short time and more rainy weather, the use of cadmium cadmium film power generation glass is the best choice.

According to Pan Jingong, the general manager of Chengdu China Building Materials Optoelectronics Co., Ltd., in 2017, the world's largest cadmium -filled film -based glass power generation glass was officially launched, with an area of ​​1.92 square meters per block, and 260 degrees of power generation in a year. The production line in Chengdu was also officially completed in the second year, with an annual production line of 1 million square meters.

"After the production line was completed, in 2018, we started construction in the Traedagawa Kaixiang Electric Industrial Park." Pan Jingong said that afterwards, many buildings such as inside and outside the province have been applied. There are 9 production lines across the country, which can produce 20 million square meters of power generation glass in one year.

In recent years, the "double carbon" goal and the deep popularity of the concept of green development have laid a solid foundation for the development of the domestic clean energy field, and the glass of power generation is becoming more and more well known. "Social demand has increased sharply. Many enterprises and government departments have found us and want to build power generation glass outside some large buildings." Pan Jingong told reporters that he is currently installing power generation glass for several buildings in Shenzhen.

It is understood that all the production lines of the company have run at full load, but due to the large demand, it still cannot meet market demand.

One square meter price is about 1,000 yuan

It takes 8-10 years to return to the book

From the current point of view of Chengdu, Sichuan Province, and even the country, most of the introduction of glass -based glass applications are some large factory buildings and commercial buildings. As for family installation, it has not been realized.

"Can our family want to install solar glass?" Recently, Qing Peng, director of the Sichuan Architectural Photovoltaic Integrated Engineering Technology Center, received a call from relatives and friends. From the current situation, the conditions are already available, but the cost is a factor that has to be considered. According to Pan Jingong, the company's production glass produced by the company is about 1,000 yuan per square meter. General families generally need to install 5 square meters. In this calculation, it takes about 8-10 years to return.

But in addition to cost issues, there are more factors that need to be considered.

On March 15 this year, Sichuan Province's Together System Engineering Technology Research Center was unveiled. The research center will be based on the core technology of photovoltaic building integrated systems to solve key technical issues of industries such as architectural solution design technology, construction thermal workers and energy -saving technology, and building construction drawing design technology. Installation system, which can innovate the breathing power generation curtain wall system, allows the building to become a micro -power plant to meet the power consumption needs of the building itself.

"There are many architectural specifications in the building, but photovoltaic buildings are still a 'uninhabited area'. Related labeling specifications need to be studied and formulated, and technical problems need to be solved." The windows, curtain walls, etc. are not generated, but after the photovoltaic building is built, related windows and curtain walls will become power generation. How to solve leak -proof and electricity safety, etc., must be continuously studied. What you need to pay attention to in the later maintenance and maintenance, whether there is a professional department to do it, is the key.

Ministry of Housing and Construction: The solar system should be installed in new buildings

"Sichuan Province Photovoltaic Building Integrated Application Technology Standards" startup preparation

On April 1 this year, the National Standard of the Ministry of Housing and Urban -Rural Development was officially implemented in "Energy Conservation and Renewable Energy Use". This specification is a coded compulsory engineering construction specification, and all provisions must be strictly implemented.

Among them, the new building should be installed with a solar system. Solar heat utilization system in the system in the system should be higher than 15 years. The design of photovoltaic components in the solar photovoltaic power generation system should be higher than 25 years. In the system, polycrystalline silicon, monocrystalline silicon, and film battery components in the system should be less than 2.5%, 3%, and 3%, respectively, and the attenuation rate within ten years. 5%, and then attenuation should be less than 0.7%each year.

The construction of a solar energy system is imperative. In this regard, Sichuan is also formulating local standards.

On April 26 this year, the Sichuan Provincial Department of Housing and Urban -Rural Development issued the "Sichuan Cadmium Cadmium Cadmium Glass Building Integrated Application Technology Standards", which provided technical standards for the future construction and installation of cadmium cadmium cadmium power generation glass.

In addition to the cadmium cadmium and power generation glass, the more comprehensive standard preparation work has been launched.

On August 16th, the local standards of the construction of the Sichuan Provincial Engineering Construction of Sichuan Province were officially launched. After the establishment of this standard, it will provide standards for citizens' home improvement glass and photovoltaic buildings.
