Ten Application Scenarios of Photovoltaic Module in Industry and Commerce (Ⅰ)

According to survey, the industrial and commercial rooftop distributed photovoltaic power generation has certain economics, and the IRR theory can reach 15% (based on the spontaneous self-use mode). The following is a brief description of ten scenarios of photovoltaic applications in industry and commerce for your reference.

1.  Hospital

Many statistics from the National Health and Family Planning Commission shows, as of the end of March 2018, that there were 31,000 hospitals, 35,000 community health service centers, 37,000 township health centers, 633,000 village clinics, and 216,000 clinics (infirmaries). 20,000 professional public health institutions.

As a public service institution with high energy consumption, hospitals will face great pressure in future energy conservation, emission reduction and consumption reduction work, and actively explore green hospital construction and development models, and promote the scientific application of green building concepts and energy conservation and consumption reduction technologies, especially important.

2. School

As of June 2017, there were 2,914 colleges and universities, nearly 260,000 primary and secondary schools, and many kindergartens and educational institutions. The school naturally has the advantages of installing photovoltaic power stations:

1>. The power station is built on the roof of the school, which is equivalent to a large science base;

2>. The school has a wide roof, good structure and stable electricity consumption;

3>. The operation of the school is stable, the property rights are clear, and financing is relatively easy.

3. Tower base station

According to statistics, China Tower Group has more than 1.9 million base stations, with a large number of communication base stations and a wide distribution range, and must ensure uninterrupted power 24 hours a day. Without access to distributed photovoltaics, in the event of a power outage, the staff needs to start diesel generators to ensure temporary power supply, and the operation and maintenance costs are high. If a distributed photovoltaic power generation system is added, both in terms of practicality and economy. , have a very high installation value.

When the weather conditions are good, the base station will give priority to the electricity generated by the photovoltaic system; when the weather conditions are bad such as rainy weather, the mains electricity is used; when the weather is bad and the power is cut off, the electricity in the battery will be used. This maximizes battery life.

4. Expressway (ground-mounted type not included)

It is reported that the current mileage of highways in China exceeds 131,000 kilometers, and it is expected to reach 15 kilometers in 2020. Photovoltaic + highways have been widely used. For example, Shandong, Hebei, Hubei, Jiangsu, and Zhejiang all make full use of the space resources of expressways. A case of organic integration of photovoltaic power generation, transportation, energy conservation and emission reduction, and road maintenance. Taking the expressway as a new carrier of photovoltaic power generation leads the new trend of photovoltaic industry, creates a new image of green expressway, and lays a good foundation for the future smart highway. Photovoltaic modules are generally installed in the service area of the highway, in the middle or on both sides of the road, in the tunnel or directly on the road.

5. Water plant (sewage treatment/water purification plant)

According to the data released by the Ministry of Housing and Urban-rural Development, there are more than 4,000 sewage treatment plants and nearly 4,000 water plants in the country. Sewage treatment and water plants have large-area water treatment pools. In addition, the average annual power consumption of sewage treatment in sewage treatment plants is relatively large. , There are great economic benefits after installing photovoltaic; photovoltaic power generation projects use the roof, sedimentation tank, biochemical tank and contact tank of the sewage treatment plant to install solar photovoltaic panels on it, which has a unique space advantage. In addition, most WWTPs are local state-owned enterprises with guaranteed business continuity.
