With the country's emphasis on green energy, photovoltaic carports are increasingly being used in real life. Photovoltaic carports are the simplest and most practical way to combine photovoltaics with buildings. They are systems that combine photovoltaic power generation with carports. They can not only solve the problem of high temperatures in open-air parking lots in summer, but also use solar energy to create clean photovoltaic energy. With related charging pile equipment, they can provide charging for electric vehicles. This system has almost no geographical restrictions and is very flexible. It can comprehensively utilize space resources to develop green new energy. As long as there is enough space, photovoltaic carports can not only achieve the benefits of green energy power generation, but also meet all the functions of conventional carports. Moreover, with the development of different application technologies, the use of photovoltaic carports in conjunction with charging piles to charge electric vehicles and electric bicycles will become more and more mature, allowing people to truly enjoy the convenience that green energy brings to life.
1. Key points for photovoltaic carport design
(1) The minimum height of the carport is generally not less than 2.2m;
(2) The load value should be determined in accordance with the "Building Structure Load Code", "Photovoltaic Bracket Structure Design Code" and other relevant specifications during design;
(3) Consider the appropriate column span and designate appropriate parking spaces between each span;
(4) Bolt connections should be used as much as possible during on-site bracket installation to reduce on-site welding, drilling or other on-site production;
(5) To ensure 25-year quality, the steel structure bracket should take anti-corrosion measures in accordance with relevant specifications;
(6) The underground geological composition and composition of the factory area;
(7) Select a suitable inverter and cable path.
2. Composition of photovoltaic carport
The photovoltaic carport is mainly composed of the foundation system, the upper photovoltaic bracket system, the photovoltaic module array, the control inverter system, the charging device system, and the lightning protection and grounding system.
The foundation system can be divided into pile foundation, strip foundation and independent foundation;
The solar carport bracket system mainly includes supporting columns, diagonal beams fixed between supporting columns, purlins connected to diagonal beams for supporting photovoltaic module arrays, related fasteners for fixing photovoltaic modules, and other diagonal braces, tie bars and other ancillary facilities. Photovoltaic carport brackets are of various types, and the conventional ones can be divided into single-column one-way, double-column one-way, single-column two-way and other types.
3. Conclusion
After the photovoltaic carport is built, it can not only protect vehicles from wind and rain, but also use solar energy to create clean photovoltaic energy for electric vehicle charging and integration into the power grid. Photovoltaic carports have almost no geographical restrictions and are very flexible and convenient to use. Moreover, after completion, the overall aesthetics of the environment has been greatly improved, which not only beautifies the environment but also saves resources, which can be said to kill two birds with one stone. In the context of increasingly tight oil resources and increasingly serious global warming, vigorously developing green energy and reducing fossil fuel consumption can reduce carbon emissions accordingly, achieve the country's dual carbon goals as soon as possible, and contribute due strength to the increasingly severe global environmental climate.
