Background

According to the report of national authorities, in 2017, the consumption of Chinese energy is 44.9 billion tons of standard coal, which is equivalent to 36 trillion-degree electricity; in 2017, the electricity generation in China is 57118.2 hundred million degrees of electricity, which accounts for 1/6 of the total energy consumption; in 2017, the photovoltaic power generation capacity of China is 1182-degree electricity, which accounts for 2% of the total power generation capacity and is increased by 78.6% on a year-by-year basis.

The data of the national energy agency are: in 2017, the electricity consumption of the whole society is 63077 hundred million kilowatt hours, and the electricity consumption is increased by 6.6 percent on a par. In 2017, the new production capacity (formal production) of the national power supply is 13372 ten thousand kilowatts, wherein the hydropower 1287 ten thousand kilowatts and the thermal power 4578 ten thousand kilowatts. In addition, the grid-connected solar power generation reaches 13025 ten thousand kilowatts.

In the last year, the solar cell installations on a global scale have reached 117GW, with china loading exceeding 50GW (distributed photovoltaic plants approaching 20 GW). Rough calculation shows that the operation investment of the solar power station is always the favorite product of the financial institution, and the current solar power station per se can be said to be a financial product.

Great significance of photovoltaic power generation: the sunlight irradiates the ground, the emitted solar energy is 1 kW/square meter, the photovoltaic efficiency is 10%, 100W electric power can be obtained, the electric power is 0.5 degree when the sunlight irradiates for 5 hours every day, and 500 degrees can be obtained every day for 1 building with a plane projection area of 1000 square meters if the roof is a photovoltaic cell; if the building height is 10 stories and the total height is 30 meters, the area of the outer wall (including the window) is 6600 square meters, half of the sunlight irradiation area is provided with the solar cell, and 3000 degrees/day of electric energy can be obtained. The requirements of the building are completely met.

In 2017, the power consumption of the whole society is 63077 hundred million kilowatt hours, and the required installed capacity is 63077 million watts (6307.7GW) according to the calculation that photovoltaic power generation generates electricity once per watt year; the required area is 630.77 billion square meters calculated as 100W of electricity generated per square meter.

It is well established that there will not be any problem of energy shortage in the future because of solar cell technology, and international energy safety in the world will be completely rewritten in the future.

The photovoltaic technology is an energy technology for realizing the sustainable development of human cleanness without pollution and exhaustion, and the current photovoltaic module needs to occupy the land and has certain requirements on bearing and illumination conditions for the top of a building on which the photovoltaic module is installed when being applied to the building. Currently, in the solar cell industry, the production of the cell panel is in a serious surplus state, that is, the biggest obstacle restricting the development of the solar cell industry is the limitation of the construction land of the solar power station. The national clear requirements are that the barren mountains and wastelands are required to be used for building the photovoltaic power station, and meanwhile, the country also strictly executes the examination and approval of land and internet access generating limits.
