What is a commercial rooftop photovoltaic power station?
Industrial and commercial rooftop power stations refer to photovoltaic systems installed on the roofs of buildings related to industry and commerce, such as government agencies, hospitals, schools, industrial and mining enterprises, and industrial and commercial parks.
The investment and construction entities are organizational units and corporate enterprises. Simply put, installing photovoltaics in factories belongs to the category of industrial and commercial photovoltaics.
The industrial and commercial rooftop power station utilizes the idle roof resources of buildings and lays photovoltaic panels on top of them, which has the advantages of low investment cost, short return period, and stable return. And most of the industrial and commercial photovoltaic projects belong to distributed photovoltaic projects, which can be developed and consumed locally, greatly improving the utilization rate of photovoltaic power generation.
What are the benefits of commercial rooftop power stations?
Firstly, activate fixed assets, reduce enterprise electricity expenses, and generate additional income for at least 20 years. Building a photovoltaic power station on the roof of an enterprise is a one-time investment for the company, with stable daily returns.
As is well known, the electricity cost for industrial and commercial use is higher than that for civilian use. After installing industrial and commercial photovoltaics, self use can be achieved, and surplus electricity can be connected to the grid. In addition to reducing electricity costs, it can also enjoy subsidies from the government for photovoltaic power generation;
Secondly, reduce enterprise energy consumption and alleviate electricity pressure. The problem of high energy consumption in production-oriented enterprises has always existed, especially during peak electricity consumption periods.
Therefore, many companies choose photovoltaic power generation because the investment cost of photovoltaics is relatively low and the power generation is relatively stable; And the photovoltaic power generation time is basically consistent with the peak period of enterprise electricity consumption, which can truly achieve peak shaving effect.
Thirdly, insulation and cooling, energy conservation and emission reduction. Photovoltaic power plants are built on the roofs of factories, which to some extent have a cooling effect, especially in summer, and can usually reduce the temperature of the workshop by 3-6 degrees. Simultaneously realizing the comprehensive utilization of solar energy and buildings, enabling enterprises to achieve energy-saving and emission reduction effects.
3. What precautions should be taken in advance when installing commercial photovoltaic roofs?
Firstly, it is necessary to have a clear understanding of the basic situation of the building. Including ownership of factory buildings, service life, building materials, area, and orientation. Puguang suggests that users develop and construct distributed photovoltaics on roofs that have a long service life and belong to themselves or the government.
In addition, once a commercial photovoltaic power station is built, it can generally operate for about 25 years. Therefore, the load of the building should be checked in advance to ensure that the power station can meet the load-bearing requirements within 25 years to avoid safety hazards and economic losses.
Secondly, it is necessary to have a clear understanding of the land use situation. Electricity companies must have land use rights and ensure that the land and its owners are not involved in any legal disputes.
Finally, it is necessary to understand the electricity consumption and business situation of the electricity consuming enterprise. Industrial and commercial enterprises are required to provide relevant data on their electrical equipment and usage, such as their historical electricity bills, peak and off peak usage periods, and so on.
