650kW Carbon Steel Integrated Solar Carport with Energy Storage and EV Charging System installed in Fujian Province represents a next-generation smart energy infrastructure solution. Combining solar power generation, on-site battery storage, and EV charging capabilities, it transforms conventional parking areas into sustainable energy hubs while meeting the demands of Fujian's humid subtropical climate and ambitious clean energy transition goals

Installation Site: Guangdong, China

Installation Date: 2024.6

Generating Capacity: 650KW

Robust Carbon Steel Carport Structure

• Material & Durability: Constructed with hot-dip galvanized carbon steel featuring multiple anti-corrosion coatings to withstand coastal humidity, salt mist, and typhoon conditions.

• Design Load: Engineered for ≥0.9 kN/m² wind load and ≥0.5 kN/m² snow load (for elevated regions) per Fujian building codes.

• Roof Configuration: Angled canopy (10°–15°) optimized for solar exposure (Fujian’s latitude: ≈25°N) with integrated rainwater management and drainage systems.

Solar PV Array (650kW DC Capacity)

• PV Modules: Approximately 1,100–1,200 units of high-efficiency monocrystalline bifacial or PERC modules (550W–600W each).

• Layout & Tilt: South-facing arrays with optimized row spacing to minimize shading, ensuring 1,400–1,600 annual sun-hour utilization.

• Mounting: Waterproof rail-based system with IP68-rated connectors to prevent moisture ingress.

Energy Storage System (ESS)

• Battery Configuration: Lithium iron phosphate (LFP) battery bank (typical capacity: 500–1,000 kWh), scalable based on load requirements.

• Functionality:

• Peak shaving to reduce grid demand charges.

• Backup power for critical loads during outages.

• Solar self-consumption optimization by storing excess daytime generation for evening/nighttime use.

• System Integration: DC-coupled or AC-coupled design with bi-directional inverters for seamless energy flow.

EV Charging Infrastructure

• Charging Units: Multiple DC fast chargers (60–120 kW) and AC slow chargers (7–22 kW) integrated under the carport.

• Smart Management: Charging stations are linked to an energy management system (EMS) that prioritizes solar/stored energy for EV charging, reducing grid dependence.
