Factory Roof Photovoltaic Power Station of Solar Power System 2.5MW

The roof area of the plant is large, the roof is flat, the power consumption is large, and the price of electricity is high, so the installed capacity is large and the power generation is also large. From the data point of view, although the proportion of industrial buildings is not large, but considering the yield and the needs of users, the photovoltaic roof project of industrial buildings is the most explosive part of the market.
A 1000 square meter roof can install about 100 kilowatts of photovoltaic power plants, which is more than the installed capacity of households. High energy-consuming industries such as paper making, chemical industry, and agricultural and sideline food processing consume more than 3,000 tons of standard coal, and are most suitable for roof photovoltaic. Most of these enterprises are large households using electricity. If the roof energy is used reasonably, it will be a potentially huge wealth. The property right of such enterprises can generally reach the right of use for more than 20 years, and is more suitable for the development of large-scale rooftop power stations of megawatts or more. It not only solves the problem of power consumption for enterprises, but also contributes greatly to social, economic and environmental benefits.
The actual data shows that the annual rate of return on the rooftop photovoltaic of the plant is about 15%, and the cost can be recovered in about 7 years, and the income can be obtained for 25 years.
The "photovoltaic + industrial and commercial" era has arrived, which has provided a new development model for enterprises, and the roof of the plant has become a "fragrant tree" and a "money tree". In other words, a company can build a photovoltaic power station on the roof or roof of its own factory building, so that the power generated by the power station can be provided for its own use and sold to the national grid, which can make full use of the idle roof of the company to make money. This model has also become the first choice for many companies to open source and reduce expenditures.
Carbon emissions trading, implementing a carbon emissions trading system.
What is carbon emission right?
To put it simply, the government issues carbon emission quotas to enterprises through total amount control, stipulates the upper limit of carbon dioxide emissions, requires enterprises to implement total management and reduction of their greenhouse gas emissions, and sets penalties for emissions that exceed the quota. then.
So for industrial and commercial owners, what are the two points of this system that need attention?
If your company belongs to key emission industries such as petrochemical, chemical, building materials, iron and steel, nonferrous metals, papermaking, electric power, aviation, etc., then it is best to hurry up and install photovoltaic power plants on the roof. This will help reduce carbon emissions and avoid spending too much. Money to buy carbon emissions.
Even if your company is not in a key emission industry, you can also use a large area of the factory's idle roof to install photovoltaic power plants. On the one hand, you can earn money by subsidies. On the other hand, industrial and commercial electricity prices are more expensive. You can save electricity by using photovoltaic power generation. Second, You can get more income by joining carbon emission trading, packaging green power from photovoltaic power plants into sellable carbon emission quotas, and selling them to high-energy-consuming enterprises that need to buy quotas.
In addition to the economic benefits mentioned above, after installing solar photovoltaic panels on the roof of the factory, it also plays a role of heat insulation and cooling. In summer, the indoor temperature of the workshop can be reduced by up to 3 ° C-7 ° C, which greatly reduces the electrical load of refrigeration equipment. Roughly calculating the installation of this project can save enterprises millions of electricity bills every year.
The photovoltaic power plant is arranged on a roof of about 330,000 square meters in 13 buildings of the factory. The average annual power generation is about 30.54 million kilowatts, and the amount of electricity generated annually is equivalent to saving 10,400 tons of standard coal for combustion, reducing about 26,000 tons of carbon dioxide emissions, and about 108,800 tons of sulfur dioxide.
During the 25-year contract period, the total power generation is expected to be approximately 764 million kWh, with an average annual power generation of approximately 30.54 million kWh.
Benefits of installing a plant roof photovoltaic power plant:
1. Revitalize fixed assets and increase corporate income
Some production enterprises have roofs ranging from several thousand square meters to tens of thousands of square meters. After installing photovoltaics on industrial and commercial roofs, these large-scale unused sites have become valuable resources, revitalizing the fixed assets of the enterprises and increasing more profits for the enterprises.
2. Save peak electricity bills and sell electricity on the Internet
Enterprises use large amounts of electricity and high peak electricity costs. After installing photovoltaic power generation, enterprises can use it on their own initiative, leaving excess electricity on the Internet. In this way, photovoltaic power generation not only solves the company's own power consumption problem, but the additional power generation can also create new economic benefits for the company.
3.Promote energy saving and emission reduction
The distributed photovoltaic power plant project of the JDSOLAR factory generates an annual amount of electricity equivalent to 10,400 tons of standard coal burning, a reduction of about 26,000 tons of carbon dioxide, and about 108,800 tons of sulfur dioxide.
Industrial and commercial photovoltaic power generation systems can reduce the energy consumption of enterprises and meet the government's energy conservation and emission reduction targets. Coupled with the vacancy in areas free from resource distribution, the advantages of building roofing are safe and reliable, no noise and no pollution.
4.Improve the environmental comfort of the plant
Large-scale laying of photovoltaic panels on industrial and commercial roofs also has thermal insulation effects, effectively reducing the plant temperature by 3-7 degrees, reducing energy consumption, and also reducing air conditioning costs.
