solar carport charging station

Solar carport charging station: a synergistic revolution of distributed energy and transportation

1. Energy upgrade of carport scenarios

The existing parking area in the world exceeds 25,000 square kilometers, of which 85% is exposed to direct sunlight. The solar carport charging station achieves triple value through the integrated design of "photovoltaic roof + energy storage system + charger":

‌1.1. Space reuse‌: The annual average power generation of a single square meter carport reaches 150-200kWh, which can support 2 electric vehicles to travel 12,000 kilometers per year;

‌1.2. Cost savings‌: Compared with independent photovoltaic power stations, the steel structure of the carport reduces the installation cost by 30%, and the energy storage system saves 40% of electricity costs by peak shaving and valley filling;

‌1.3. Emergency guarantee‌: The built-in energy storage unit can maintain 72 hours of charging service when the power grid fails, and the power supply reliability in disaster scenarios is increased to 99%.

2. Technological breakthroughs and solution practices

2.1. Efficient photovoltaic module integration

The double-sided power generation glass and flexible bracket are used, and the inclination angle of the photovoltaic panel can be automatically adjusted with the solar altitude angle (such as Hongjiali solar storage and charging), and the power generation efficiency is increased by 25%. The measured data of a carport in a certain science and technology park shows that the annual power generation of 10MW installed capacity reaches 12.5 million kWh, covering 80% of the electric vehicle electricity demand in the park.

2.2. Intelligent energy management

Hongjiali Energy Router realizes the dynamic allocation of "photovoltaic-energy storage-charging", giving priority to the use of green electricity for grid connection, and the storage ratio of surplus electricity reaches 95%. In a case of an industrial park, the system reduces the comprehensive charging cost to 0.35 yuan/kWh, which is 60% lower than direct charging from the power grid.

2.3. Modular rapid deployment

Standardized carport units (30 parking spaces/group) support 72-hour assembly, and photovoltaic components and chargers are plug-and-play. A community adopted this solution and built a 500-parking charging network in 3 months, which is 70% shorter than the traditional construction period.

3. Typical application scenarios and revenue models

‌3.1. Commercial complex‌

A certain MixC carport has an installed capacity of 5MW, an annual power generation income of 6.2 million yuan, and an IRR of 18.6% after adding the charging service fee. The V2G system provided by Hongjiali supports reverse power supply for vehicles, and a single vehicle can make a profit of 45 yuan per time during the peak period of nighttime electricity prices.

3.2. Industrial Park ‌

A certain automobile factory built a 20MW carport power station, which reduced carbon dioxide emissions by 12,000 tons per year, met the full electrification needs of commuter vehicles and logistics vehicles in the factory area, and saved 14 million yuan in energy expenses per year.

3.3. Transportation Hub ‌

A certain airport T3 terminal carport integrates a 500kW super charger, photovoltaic power generation directly supplies charging equipment, and the waiting time for passengers to charge is shortened to 15 minutes, and the average daily service capacity is increased to 300 vehicles.

Solar carport charging stations are being upgraded from single charging facilities to new urban energy nodes. The full life cycle solutions provided by Hongjiali and other companies promote the deep synergy of distributed photovoltaics and transportation electrification through the integration of technological innovation and business models, and provide a replicable business model for the global carbon neutrality goal.
