With the introduction of the "14th Five-Year Plan", "carbon neutrality" was once sent to the hot search. Chinese people talk about "carbon neutrality", what exactly is it?

In layman's terms, it is an enterprise, group or individual that offsets the carbon dioxide directly or indirectly generated in production and life through afforestation, energy conservation and emission reduction, and achieves zero emissions of carbon dioxide and other greenhouse gases. To put it bluntly, it is a solution to the greenhouse effect.

There are four main ways to achieve zero carbon emissions: zero carbon energy, zero carbon transportation, zero carbon buildings and zero carbon living. Among them, zero-carbon energy occupies the most important position!

In "Constructing a Modern Energy System" in the outline of the "14th Five-Year Plan", the focus of my country's energy development in the next five years is pointed out: accelerate the development of non-fossil energy, adhere to both centralized and distributed energy, and vigorously improve wind power and photovoltaic power generation. scale.

As a representative of clean energy, photovoltaics can truly achieve zero carbon emissions, and have the advantages of low cost, safety and efficiency, and play an important role in my country's energy transformation.

According to data from the China Photovoltaic Industry Association, by the end of 2020, my country's cumulative installed photovoltaic capacity exceeded 250 GW, ranking first in the world for 6 consecutive years; polysilicon and module production ranked first in the world for 10 consecutive years and 14 years respectively; polysilicon, silicon wafers The four links of , cells and modules accounted for more than two-thirds of the global cumulative output. In 2020, my country's newly installed photovoltaic capacity will reach 48.2 GW, ranking first in the world for eight consecutive years.

It can be seen that my country has become the largest photovoltaic market in the world, and the achievement of this achievement is closely related to the upstream, middle and downstream enterprises. So why do so many companies choose photovoltaics, and what are the benefits of installing distributed photovoltaics?

First of all, the distributed photovoltaic power station is built on the roof of the enterprise workshop, and the enterprise can adopt the power consumption mode of self-generation and self-use, and the surplus power is connected to the grid. On the one hand, enterprises give priority to the use of electric energy produced by photovoltaic power plants, which reduces the cost of electricity consumption in the production process, thereby reducing the energy consumption of enterprises. On the other hand, in addition to the company's own use, the excess electricity can be incorporated into the national grid, which not only contributes to social electricity consumption, but also obtains electricity fee income, which increases the company's competitive advantage.

Secondly, the distributed photovoltaic power station is mainly constructed on the roof of the enterprise workshop, which revitalizes the fixed assets of the enterprise and taps and utilizes the idle resources of the enterprise. As a result, the company's original idle factory roof can be effectively used, thereby improving industrial efficiency and creating economic value.

Third, photovoltaic power generation is based on solar energy resources. In the process of power generation, it truly achieves zero output of pollution sources such as dust, waste water, waste residue, and noise. It not only contributes to the country's development of clean energy and the construction of a clean, low-carbon, safe and efficient energy system, but also helps to achieve the goal of "carbon peaking and carbon neutrality", thereby enhancing the company's brand image and influence.

To sum up, no matter from which point of view, the enterprise layout of distributed photovoltaic is a huge profit.

As we all know, the roofs of corporate workshops have always been the darling of the photovoltaic industry. The use of idle factory roofs to build photovoltaic projects can not only reduce energy consumption, but also make full use of idle resources, play a role in energy conservation and emission reduction, and bring benefits to factories. Huge economic and environmental benefits can be described as serving multiple purposes with one stone!

The basic equipment of the distributed photovoltaic power generation system on the roof of the factory includes solar photovoltaic cell modules, photovoltaic square array brackets, DC combiner boxes, DC power distribution cabinets, grid-connected inverters, transformers, AC power distribution cabinets and other equipment, as well as the power supply system Monitoring devices and environmental monitoring devices. Its operation mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the output electric energy from solar energy, and sends it to the DC power distribution cabinet through the DC combiner box, and the grid-connected inverter converts it into AC power supply. The building itself is loaded, and excess or insufficient electricity is regulated by connecting to the grid.

Six benefits of installing solar photovoltaic power on 1F:

◆Solar energy is inexhaustible, and the solar radiation received by the earth's surface can meet 10,000 times of global energy demand! As long as solar photovoltaic systems are installed on 4% of the world's deserts, the electricity generated can meet the world's energy needs. Yes! Solar power generation is safe and reliable and will not suffer from energy crises or fuel market instability;

◆Solar energy can be used everywhere, and can supply power nearby without long-distance transmission, avoiding the loss of long-distance transmission lines;

◆Solar energy does not require fuel, and the operating cost is very low;

◆Solar power generation has no moving parts, it is not easy to be damaged, and the maintenance is simple, especially suitable for unattended use;

◆Solar power generation will not produce any pollution, noise and other public hazards, has no adverse impact on the environment, and is an ideal clean energy source;

◆The construction period of the solar power generation system is short, convenient and flexible, and the amount of solar energy can be added or reduced arbitrarily according to the increase or decrease of the load, so as to avoid waste.

Eight advantages of 2F industrial rooftop photovoltaic power generation:

◆Using idle roofs and floors to revitalize fixed assets to increase corporate income.

◆Save peak electricity bills for enterprises (peak power generation is the most during the day), and the surplus electricity can be sold online.

◆Reduce the temperature inside the factory, increase the working comfort and the cost of cooling in summer.

◆It can better fulfill the energy-saving and emission-reduction targets stipulated by the government.

◆It is not limited by the geographical distribution of resources, and it is safe and reliable, without noise and pollution, by taking advantage of the advantages of building roofs.

◆Using access from the nearest user side, no need for long-distance transportation, avoiding the loss of long-distance transmission lines.

◆The construction period of the solar power generation system is short, and the time spent on obtaining energy is short, convenient and flexible. According to the increase or decrease of the load, the solar array can be added or reduced arbitrarily to avoid waste.

◆Better investment income, can run for at least 25 years. It does not require fuel, has low operating cost, and is not easy to produce polluting wastes during power generation. It is an ideal clean energy source.
