The cost structure of a solar carport involves multiple factors, with significant variations depending on functionality, material selection, design complexity, and policy support. Below is a detailed analysis based on research findings: 1.PV Modules Account for 40%-60% of total costs, representing the core expenditure. Module types (monocrystalline silicon, polycrystalline silicon, thin-film) directly impact pricing. Monocrystalline silicon offers higher efficiency but at a higher cost (~CNY 2.2/W), while polycrystalline silicon provides better cost-effectiveness. 2.Mounting System Material selection: Aluminum alloy brackets are lightweight and corrosion-resistant but costlier. Steel structures offer stronger load-bearing capacity but require anti-corrosion treatment (e.g., hot-dip galvanizing), with lower upfront costs but more frequent maintenance. Design considerations: Wind/earthquake resistance must be addressed. Customized structures for complex terrains (e.g., mountainous areas) increase costs by 10%-20%. 3.Inverters & Electrical Systems Inverters cost ~CNY 0.3-0.5/W, accounting for 8%-10% of total investment. Electrical systems (cables, combiner boxes, etc.) constitute ~5% of total costs. Additional 3%-5% expense required for smart monitoring systems (e.g., SCADA). 4.Charging Facilities (Optional) Charging pile configuration costs ~CNY 10,000-30,000 per unit. A 30-charging-point carport requires CNY 300,000-900,000. Fast-charging piles incur higher costs. 5.Foundation Structures Foundation type significantly impacts costs:Helical piles suit hard soil layers (~CNY 500/pile). Concrete foundations are preferable for soft soil, increasing costs by 20%.

The ground-mounted dual-axis tracker system is a key technology for enhancing the efficiency of photovoltaic power generation. Its design and installation need to meet multiple technical requirements to ensure stability, tracking accuracy and long-term reliability. The following are the main requirements and related technical details: 1. Requirements for Foundation and Soil ☛Soil conditions The soil quality within a depth of 800 mm on the surface of the installation area should be Class II ordinary hard soil with a firmness coefficient of ≥0.7 (which requires forceful excavation with a shovel and a few require excavation with a pickaxe). If the soil quality is soft, equivalent reinforcement treatment should be carried out. The foundation should avoid settlement or sandy loam. If necessary, the bearing capacity should be enhanced by hardening concrete or backfilling with crushed stones. ☛Concrete foundation The foundation size should be ≥600×600×700 mm, and C25 or higher strength concrete should be used (recommended mix ratio: cement 183 kg/m³, water 600 kg/m³, sand 1,192 kg/m³, crushed stone 450 kg/m³). The embedded anchor bolts or expansion bolts need to be precisely calibrated (verticality tolerance ≤1/100) to ensure the main rods are installed stably. ☛Helical piles or counterweight foundations For hard soil layers, spiral pile foundations can be adopted, with a depth of 3 to 6 meters. No concrete curing is required, making it suitable for rapid installation. For sandy land or temporary projects, counterweight foundations (such as concrete blocks or water tanks) can be used, and the counterweight should exceed 1.5 times the wind load overturning moment. 2. Structural Installation Requirements ☛Main rods and supporting structures The main pole needs to be calibrated in the north-south direction through a compass and fixed to the concrete base with expansion bolts to ensure horizontal and vertical accuracy. The truss base needs to be equipped with support rods, connecting rods and V-shaped brackets to reduce the overall height and meet the requirements of bidirectional tracking. ☛Installation of mechanical components Dual-axis mechanisms (such as worm gear reducers and linear actuators) need to be precisely aligned and adjusted in the longitude and latitude directions through steel wire ropes or gear transmission. The solar panels are fixed by C-shaped/U-shaped guide rails and pressure block fixtures. Drainage holes need to be left to prevent water accumulation. 3. Electrical and Sensor Configuration ☛Controller installation The controller should be installed at a height of 1.3 to 1.5 meters above the ground, away from metal obstructions. The main power supply should be directly connected to the fire protection power supply. The use of plugs is strictly prohibited. The wiring should be neatly bound, with a cable allowance of ≥ 200mm, and the marked numbers should be consistent with the drawings. ☛Sensor debugging The light sensor needs to be clean and unobstructed. During installation, manually adjust and align it with the direction of the sun to ensure that the shadow of the light-blocking ball covers the scattering meter. The wireless inclinometer needs to be installed on a fixed bracket. The distance between the antenna and the collector should be no more than 500 meters to avoid interference signals from metal planes. 4. Debugging and Calibration ☛Initial debugging Start the device in the sunlight, manually adjust it to the sun position and then switch to the automatic mode. Check the deviation of the light sensor and make fine adjustments. Verify the tracking accuracy using a direct radiation meter to ensure that the error is ≤1°. ☛Calibration of the tracking system The dual-axis tracker needs to have its limit switches, motor status and gear clearance checked regularly to prevent oscillation or jamming. The GPS module needs to be calibrated to the standard time to avoid reset errors at night. 5. Safety and Maintenance ☛Wind-resistant design The structure should be capable of withstanding a maximum wind speed of 40 m/s. In hurricane areas, stay cables or wind shields should be installed. It is recommended to remove the solar panels when the wind speed exceeds 17.2 m/s. Regularly check the tightness and corrosion of the bolts. Especially in coastal areas, 316L stainless steel or galvanized materials should be used. ☛Maintenance requirements Clean the dust on the sensor surface every quarter and check the electrical grounding (resistance ≤4Ω). Seasonal adjustment of the tilt Angle (such as ±15° during the spring and autumn equinoxes) can increase power generation by 5% to 8%. 6. Environment and Compliance Site requirements: At least 3 meters away from high-voltage lines, at least 5 meters away from buildings, and the illuminance at night should be at least 15 lx. Environmental compliance: Avoid damaging the original soil layer, reduce excavation for spiral pile foundations, and meet environmental protection standards. By meeting the above requirements, the dual-axis tracking system can increase the average daily power generation by 15% to 40% while ensuring a service life of 25 years.

*Structural Design and Functional Integration 1. Carport size and vehicle adaptability Height design: The recommended height for the parking area of ordinary sedans is 2.5 to 3.0 meters, for SUVs and medium-sized vehicles it should be 3.0 to 3.5 meters, and for special areas such as fire lanes, it should be no less than 4.0 meters. Span and width: The span of a single span is usually 6 to 12 meters. The recommended width for a double-row parking space is 6.0 to 7.0 meters, and the width of the middle passage should be no less than 1.2 meters. Photovoltaic panel layout: The standard size of the module is 1.0m×2.0m. During installation, a transverse gap of ≥ 0.1m and a longitudinal gap of ≥ 0.3m should be reserved to avoid shadow shading. 2. Photovoltaic system configuration Component selection: Amorphous silicon thin-film modules, due to their superior weak light performance, are suitable for installation at complex angles (such as the arc-shaped roof of a bus stop), with an average annual power generation efficiency of up to 100kWh/㎡. Power generation strategy: Prioritize the adoption of the "self-generated and self-consumed, surplus power fed to the grid" model, support the integration of 180kW fast charging piles, and combine V2G technology to achieve vehicle-to-grid interaction. Energy storage and grid coordination: On rainy days, energy storage systems should be configured or connected to the grid to ensure the stable operation of charging stations. *Materials and Construction Standards 1. Requirements for structural materials Steel: The steel used for photovoltaic brackets should be free of cracks and rust, and meet the relevant standards for surface corrosion grades. In northern regions, the design for snow pressure resistance should be strengthened. Aluminum alloy: It has excellent anti-corrosion performance and is suitable for high-humidity environments. Pre-installed accessories can shorten the installation time by 30%. 2. Construction process Civil engineering section: It includes geological investigation, independent foundation construction (dimensions ≥0.8×0.8×1.0 meters), and drainage system design. Installation stage: After the bracket is installed, adjust the inclination Angle (optimized according to ±5° local latitude). Flame-retardant materials should be used for cable laying, and the grounding resistance should be ≤4Ω. Solar carports with charging stations are a model of "green buildings + smart transportation", and their design needs to take into account functionality, safety and economy. Through modular design, material innovation and policy coordination, such projects can not only reduce operating costs, but also enhance the ESG image of enterprises. In the future, with the popularization of BIPV (Building Integrated Photovoltaic) technology, solar carports will become a standard feature of urban infrastructure, contributing to the global energy transition.
