Why should a solar photovoltaic system be installed on the corporate roof ?


At present, the domestic economy continues to develop, and energy shortages and environmental pollution have become two major issues that slow long-term economic development. The development of solar renewable energy has become an important development direction of global energy.

Among them, the renewable energy solar photovoltaic system is an environmentally friendly and inexhaustible new energy source. At present, photovoltaic power stations are mainly used in two ways. The first is a large-scale ground photovoltaic power station, which is mainly distributed in suburbs or remote deserts, hills and other areas ; The second is a distributed photovoltaic power station, which is usually used on the roof of homes, industrial and commercial roofs. Industrial and commercial roofs are important application sites;


solar photovoltaic system


Ground photovoltaic power stations refer to solar photovoltaic power stations that are connected to the public power grid and share power supply tasks. The ground photovoltaic grid-connected power station consists of a square battery array, grid-connected inverters, and photovoltaic-integrated integrated intelligent substations. The photovoltaic square array directly converts solar energy into electrical energy under the condition of light, and converts DC power to AC power through a grid-connected inverter. Then it is connected to the public power grid after being boosted by the photovoltaic integrated intelligent substation, and jointly assumes the power supply task. The country is already strongly supporting it.


"Photovoltaic + industrial and commercial" has become a new development model for enterprises, and the roof of the plant has become a "solar panel roof". In other words, companies can build a photovoltaic power station on the roof or roof of their own factory like the roof of an ALLTOP company, so that the power generated by the power station can be provided for their own use or sold to the national grid, which can be fully utilized. Enterprises idle the roof to make money, this model has also become the first choice for many enterprises to open source and reduce costs.

According to reports, many domestic companies have already keenly smelled business opportunities. JD.com announced that it will fill distributed photovoltaic power generation on the roofs of logistics parks with a size of more than one million square meters across the country. . Among them, ALLTOP has successfully completed the installation of solar photovoltaic power generation systems on many occasions; for example, Kenya has officially completed the grid connection of cities and towns on February 6, 2018, and the remaining 9 cities and towns have been successfully connected to the grid in October 2018 to successfully generate electricity; African dried fruits in 2018 Also successfully installed. Through these cases, we can see that the reason why "solar photovoltaic + industry" is continuously optimistic, according to relevant statistics: the scale of China's industrial and commercial rooftop photovoltaic market will exceed 210GW.

And with the continuous advancement of urbanization, this number is likely to reach 300GW in 2040. Among them, the annual installed capacity in 2016 is 6.4GW, and the annual installed capacity in 2040 may reach 125GW. As a member of the wave of the industrial and commercial photovoltaic industry, Nenghuanbao always adheres to its own pace and has its own insistence. From the perspective of the enterprises themselves, the establishment of these power stations can help them save electricity costs, revitalize their fixed assets, tap and use idle resources of enterprises, improve industrial efficiency, and create economic value!

Why do companies install solar photovoltaic power generation systems


Local policy requirements: Eligible industrial and commercial roofs are mandatory to build supporting photovoltaics

At present, there are many measures at home and abroad, which stipulate that the annual comprehensive energy consumption exceeds 1,000-5000 tons of standard coal, the annual power consumption of commercial enterprises exceeds 3 million kilowatts, the energy consumption of 10,000 yuan of industrial added value is higher than 1 ton standard coal, and the roof area The roofs of enterprises over 1,000 square meters must be distributed.

Forced supporting construction of distributed provinces continues to increase installed capacity. For development companies, the development obstacles are relatively small. Many companies are gradually turning to distributed project investment, and competition is fierce.


Emissions trading startup has to be installed

According to the `` Notice on Effectively Doing a Good Job in Starting the National Carbon Emissions Trading Market '' issued by the National Development and Reform Commission of China in early 2016, starting from January 1, 2017, it is necessary to start national carbon emissions trading and implement a carbon emissions trading system. .


So for industrial and commercial owners, what are the two points of this system that need attention?


1.If your company belongs to key emission industries such as petrochemical, chemical, building materials, iron and steel, nonferrous metals, papermaking, electricity, aviation, etc., it is best to hurry to install photovoltaic power plants on the roof, which will help reduce carbon emissions, not much Spend money on carbon emissions.

2. 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 a solar power generation system.On the one hand, you can earn electricity fees, on the other hand, the industrial and commercial electricity prices are more expensive, and you can save by using photovoltaic power generation. Electricity charges, and secondly, you can get more income by joining carbon emissions trading, packaging green power from photovoltaic power plants into saleable carbon emission quotas, and selling them to high-energy-consuming enterprises that need to buy quotas.


Benefits of installing photovoltaic systems on industrial and commercial roofs


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 the installation of photovoltaics on industrial and commercial roofs, these large 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 have large power consumption and high peak electricity costs. After installing solar photovoltaic power generation, enterprises can use it on their own initiative, leaving excess electricity on the Internet. For example, the price of electricity used by enterprises in the Congo region in Africa is generally 0.67 yuan / kWh. Enterprises can save 0.67 yuan by themselves when they use their own electricity. The unused electricity can also be sold to the power grid. The grid purchase price is 0.35 yuan / kWh. 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 conservation and emission reduction, and generate good social benefits

Industrial and commercial solar photovoltaic power generation systems can reduce the energy consumption of enterprises and achieve government-defined energy conservation and emission reduction targets. Coupled with the vacancy in areas free from resource distribution, the advantages of building roofs are safe and reliable, no noise and no pollution. This is also one of the main reasons for many photovoltaic institutions to build photovoltaic power generation.


Solar photovoltaic power generation system "charges" poverty alleviation


It is understood that the small-scale distributed solar photovoltaic power generation system on the roof refers to the construction of power users on nearby roofs, grounds, ponds, breeding farms, plantations and other convenient places to use, and directly converts them into electricity after receiving solar radiation with solar panels. Method, and then convert the generated electricity into 220 volts or 380 volts of AC power that can be connected to the grid and then integrate it into the national power grid to achieve spontaneous and self-use. .
