How strong is the power generation capacity of the world's highest altitude photovoltaic power station?

The closer you are to the sun, the stronger the power generation!

China's photovoltaic industry is very strong, how strong is it? The two sets of data confirm the outstanding achievements of my country's photovoltaic industry.

In the manufacturing process, the output of polysilicon and components has ranked first in the world for 11 consecutive years and 15 years respectively, and the output of main links accounts for more than 2/3 of the world.

In terms of application, the cumulative installed capacity of photovoltaic power generation has rapidly increased from 6.5 GW at the end of 2012 to 306 GW at the end of 2021, ranking first in the world for seven consecutive years.

What factors does the power generation capacity of photovoltaics depend on?

Photovoltaic panels can only generate electricity when there is sunlight. In addition to being affected by the difference in power generation capacity between photovoltaic panel materials, the power generation capacity of photovoltaic power generation depends on the intensity of light, which is indeed the case.

Regardless of hardware factors, how much electricity a photovoltaic panel can generate mainly depends on the effective power generation hours of the photovoltaic panel in the installation area. Due to the different light hours in different regions, the length of time that photovoltaic panels can generate electricity is also different.

And the total number of times that photovoltaic panels can generate electricity in a year, we call it the "annual effective power generation hours" of photovoltaic power generation. The number of hours of effective power generation in different regions is different, and the power generation capacity of photovoltaic panels with the same power is also different.

Under the condition that the optimal installation inclination is also guaranteed, areas with good lighting conditions, such as Northwest China, Inner Mongolia and other areas, can generate 1.6 kWh of electricity per year, while in East China, such as Jiangsu, Zhejiang and Shanghai, the annual electricity generation is only 1.6 kWh. Can reach 1 degree / watt.

It can also be understood in this way. Of course, the closer you are to the sun, the stronger the energy obtained from the sun. Under the same conditions, the power generation capacity of the photovoltaic panel will be stronger.

How can we get closer to the sun? Of course, the higher the altitude, the closer it is!

How strong is the power generation capacity of the world's highest altitude photovoltaic power station?

The junction of southern Tibet and northern Tibet in my country is 4,700 meters above sea level. It has sufficient sunshine and strong solar radiation. The annual sunshine hours can reach 2,881 hours, which has the natural advantage of developing the photovoltaic industry.

Yangyi photovoltaic power station is located in this area, which is the highest photovoltaic power station in the world. The station was successfully connected to the grid on December 30, 2019, and it also set a new record for the highest photovoltaic power station in the world.

The total installed capacity of Yangyi Photovoltaic Power Station is 10 megawatts, which can generate 55,000 kWh of electricity per day, 20 million kWh of electricity per year, and the annual power generation can reach 2.0 kWh/watt.

In the context of the "dual carbon" goal, photovoltaics usher in development opportunities. According to authoritative forecasts, from 2022 to 2025, the average annual installed capacity of photovoltaics in my country will reach 85 million kilowatts to 101.25 million kilowatts, which is equivalent to adding about 4 Three Gorges power stations every year.

In fact, when it comes to the place closest to the sun, we still have a vast area that has not been developed. That's right, a space solar power plant.

Space solar power station, also known as space photovoltaic power station, mainly uses high altitude for photovoltaic power generation, and then transmits it wirelessly. Through microwave, it can provide directional power supply or mobile power supply to remote areas and disaster-stricken areas.

The construction of China's first space solar power plant test base has begun. It is located in Bishan District, Chongqing City. It will simulate and verify the early demonstration and verification of space solar power plant, space information network and wireless microwave energy transmission technologies.

According to the plan, around 2025, the base will realize small and medium-scale stratospheric solar power plants, as well as grid-connected power generation, and after 2025, the infrastructure will carry out system application work for large-scale space solar power plants.

It is believed that with the development of wireless power transmission technology and the breakthrough of China's aerospace technology, the dream of building a space photovoltaic power station at an altitude of 36,000 kilometers from the earth will soon be realized!
