As a new application form of distributed photovoltaic power generation, photovoltaic carports are receiving increasing attention and application worldwide. Although many investors who have been exposed to rooftop photovoltaics in the early stages may have concerns about the relatively high construction cost of photovoltaic carports and the long investment return cycle, in-depth analysis reveals that photovoltaic carports have become an important direction for the construction of new energy infrastructure, both from the perspective of international development trends and domestic policy guidance. Compared with traditional rooftop photovoltaics, photovoltaic carports have unique comprehensive advantages, and their investment value is being re recognized by the market.

From the perspective of service life and economic benefits, photovoltaic carports demonstrate significant advantages. The service life of ordinary membrane structure carports is usually 8-10 years, while photovoltaic carports use high-quality photovoltaic modules and steel structure frames, with an overall service life of 25-30 years, which is about three times that of the former. This means that after a single investment and construction, it can be used for a long time without the need for reconstruction, greatly reducing maintenance costs throughout the entire lifecycle. It is particularly noteworthy that the sunshade performance of photovoltaic carports far exceeds that of traditional carports. Its photovoltaic panels not only effectively block ultraviolet rays, but also convert most of the solar energy into electrical energy, making the temperature under the carport 10-15 ¡æ lower than that of ordinary carports. In summer, it can effectively protect vehicles from high temperature exposure and extend their service life. This added value is incomparable to traditional carports.

Photovoltaic carports have unique advantages in terms of aesthetics and corporate image shaping. Modern photovoltaic carports adopt streamlined design and modular construction, with a simple and atmospheric overall shape, resembling a high-tech landscape building from a distance. For large industrial parks, commercial complexes, and other places, building photovoltaic carports can not only achieve self-sufficiency in green electricity, but also significantly enhance the environmental image and social responsibility of enterprises. Many internationally renowned companies use photovoltaic carports as an important carrier to showcase their sustainable development concepts, and the increase in brand value often brings commercial returns beyond the electricity revenue itself.

With the rapid development of the new energy vehicle industry, the combination of photovoltaic carports and charging infrastructure has shown great potential. The current number of new energy vehicles in China continues to rise, and the demand for charging facilities is showing explosive growth. The combination of photovoltaic carports and charging stations has created an integrated solution for "photovoltaic storage and charging": during the day, photovoltaic power generation can be directly supplied to charging stations, and excess electricity can be stored or connected to the internet; At night, power can be supplied through the power grid or energy storage system. This mode can not only reduce charging costs by 30-50%, but also effectively alleviate the pressure on the power grid during peak electricity consumption periods. Especially in industrial parks, commercial centers, and other places, photovoltaic carport charging stations can not only meet the charging needs of employees and customers, but also achieve localized production and consumption of energy, making them an ideal choice for the construction of new power systems.

From international experience, developed countries such as Europe, America, Japan, and South Korea have already regarded photovoltaic carports as an important component of urban new energy infrastructure. With the promotion of the "dual carbon" target and the improvement of distributed photovoltaic policies in China, photovoltaic carports are entering a period of rapid development. Compared to rooftop photovoltaics, photovoltaic carports have unique advantages such as flexible installation, no additional land occupation, and perfect integration with building functions. With the improvement of photovoltaic module efficiency and cost reduction, the investment return period of photovoltaic carports has been shortened to 5-7 years. Coupled with subsidy policies from local governments, the actual return period may be even shorter. Taking into account multiple values such as electricity revenue, vehicle protection, and image enhancement, photovoltaic carports are becoming the preferred new energy solution for industrial parks, commercial centers, public institutions, and other places, with a very broad market prospect.
