In constructing photovoltaic power stations, the design, material selection, and installation methods of the support system play a crucial role. This system serves as the structure that supports photovoltaic modules and directly impacts the stability, safety, and power generation efficiency of the photovoltaic power station.
Support Materials:
1.1 Steel: The construction of most photovoltaic power stations primarily relies on steel for supports due to its exceptional strength, corrosion resistance, and weatherability.
1.2 Aluminum Alloy: Given its lightweight nature, corrosion resistance, and recyclability, aluminum alloy supports are ideal for projects that require weight sensitivity and adhere to high environmental standards.
Support Structure:
2.1 Fixed Support: Serving as the simplest structure, fixed supports are anchored to the ground or roof, making them suitable for both ground-based power stations and rooftop installations.
2.2 Single-Axis Tracking Support: Equipped with a single-axis (usually horizontal) tracking feature, these supports can adjust the tilt angle of the components in accordance with the sun’s movement.
2.3 Dual-Axis Tracking Support: Featuring dual-axis (horizontal and vertical) tracking capabilities, these supports enable more precise sun tracking and enhance power generation efficiency.
3.1 Ground Installation: Ideal for large-scale photovoltaic power stations, this method involves directly fixing supports to the ground.
3.2 Roof Installation: Suitable for commercial and industrial roofs or expansive roofs, supports are mounted on the roof using bolts or other securing methods.
3.3 Floating Installation on Water Surface: Designed for water surface power stations, these supports float on the water and are anchored in place using floats.
Key Points of Support Design:
4.1 Consideration of Wind Load and Snow Load: Tailor the support system design to withstand the maximum wind and snow loads based on the project’s specific meteorological conditions.
4.2 Foundation Design: Ensure a stable foundation that adapts to groundwater levels and soil types, employing appropriate foundation design strategies.
4.3 Anti-corrosion Treatment: Select corrosion-resistant materials for supports and implement anti-corrosion measures to extend their service life.
Matters Needing Attention in Project Implementation:
5.1 Conduct an environmental impact assessment before design and installation to ensure minimal adverse effects on the surrounding environment.
5.2 Strictly adhere to relevant safety standards and regulations to guarantee the safety of personnel during the installation and maintenance phases of the support system.
5.3 Implement rigorous quality control measures during manufacturing and installation to ensure the support system meets required standards.
Project Experience and Case Analysis:
6.1 Draw on the experience of similar projects, learning from the successes and failures of other photovoltaic power stations in terms of support design and installation.
6.2 Conduct a thorough site survey prior to project commencement to gather information on terrain, soil quality, meteorology, etc., aiding in the development of the most suitable support design.
Life Cycle Cost Analysis:
7.1 Consider equipment lifespan during support system design and material selection to minimize maintenance costs.
7.2 Assess maintenance costs associated with different support types to choose the most economical and sustainable option.
Weatherability and Environmental Adaptability:
8.1 Select supports with strong wind resistance based on the project location’s wind speed conditions.
8.2 For highly corrosive environments, opt for corrosion-resistant materials or implement special corrosion protection measures.
Maintainability Design:
9.1 Incorporate modularity into the support system design to allow for individual module replacement or repair without compromising the overall system.
9.2 Ensure ease of maintenance for all support system components, reducing maintenance time and costs.
Environmental Protection and Sustainability:
10.1 Prioritize material recyclability when selecting support materials to lessen environmental impact.
10.2 Consider terrain protection during support layout planning to minimize damage to the natural environment.
Technological Innovation and Future Upgradability:
11.1 Stay abreast of the latest technologies and innovations in the support system field, selecting designs and materials that cater to future requirements.
11.2 Incorporate upgradability into the support system design to accommodate advancements and changes in photovoltaic technology.
