An article to learn about photovoltaic carports
2023-12-19
In addition to laying in factories, roofs, PV systems can also be combined with carports, which is the easiest and most feasible way to combine with buildings and parking power generation. It is widely used in factory parks, commercial districts, hospitals, schools and other places.
Application of photovoltaic carport
As a distributed photovoltaic project (or as a part of it), PV carport is combined with charging piles and new energy electric vehicles, utilizing the photovoltaic modules located on the roof of the carport to generate electricity. And through the charging device stored in the battery, or directly supplied to the electric car charging use, self-generated self-consumption, and even can be surplus power on-line.
Photovoltaic carport is a new type of power generation and the future development trend. The earlier it is installed, the greater the benefit. It mainly consists of mounting system, battery module array, lighting and control inverter system, charging device system and lightning protection and grounding system. The mounting system mainly includes support columns, inclined beams fixed between the bracket columns, purlins connected to the inclined beams to support the solar cell module array, and fasteners to fix the battery module array.
There is a convergence box under each carport, through which the solar panels at the top of the carport will collect the absorbed electricity in a unified way. After transmission, the power is sent to the inverter, which turns the DC power into AC power, and then it can be delivered to the power grid to complete the power generation.
Characteristics of photovoltaic carport
Beautiful modeling. Photovoltaic panels replace the traditional carport membrane structure steel roof, blue photovoltaic panels glitter in the sun, adding a bright landscape.
Strong practicality. Not only can prevent the car from being exposed to the sun and rain, but also can provide a steady stream of green power for charging new energy vehicles, enterprise electricity, and so on.
Energy saving and environmental protection. The use of solar power generation, no emissions, no noise, no pollution, is green and clean energy.
Lower cost. The cost per square meter is low, including the steel structure, photovoltaic system and all other projects. It is only about one thousand yuan per square meter, which is only increased by three to four hundred yuan per square meter compared with ordinary membrane structure carport. And the increased cost can be recovered through the electricity subsidy at national, provincial and municipal levels.
Long-term benefits. The photovoltaic carport system continues to generate electricity for 25 years, after recovering the cost, you can enjoy the net income brought by the photovoltaic carport.
Types of PV carport:
Double carport
Multi-parking carport
Most of the photovoltaic carport is modular design, can be used individually or multiple combinations, easy to expand. Less than a few parking spaces, more than a few hundred, the flexibility is relatively strong. If ordinary PV modules are used, the overall cost is low. If the installed capacity is large, the yield is high and the payback period is short.
Photovoltaic carport case:
1.Photovoltaic carport with photovoltaic modules mounted on top of the carport
2.Photovoltaic carport with photovoltaic modules as structure
3.Movable photovoltaic carport
Tips:
Although the photovoltaic carport is within the scope of the overall construction land of the enterprise, if there is no relevant construction planning permission, it may be classified as unauthorized building. When the government requires demolition, the photovoltaic carport will not get the relevant compensation. Therefore, before construction, you need to go to the planning department for the relevant procedures and obtain the appropriate license documents.
Due to the instability of solar energy resources and the high cost of batteries, in order to ensure the normal operation of photovoltaic carports, it also needs to cooperate with the power grid.
