Ground-mounted solar systems are gaining popularity, especially for large-scale solar projects, due to their flexibility, scalability, and higher efficiency potential. In this article, we will explore the key benefits of ground-mounted solar systems, share essential installation tips, and provide real-world data to help you understand why they are becoming a preferred choice for commercial, industrial, and utility-scale solar projects.
Ground-mounted solar systems are solar panel installations placed on the ground, typically using support structures such as racks, poles, or frames. These systems can be installed in open spaces, fields, or on land that may not be suitable for other types of infrastructure, offering more versatility than roof-mounted solar panels.
Unlike rooftop solar installations, ground-mounted systems can be positioned at the optimal angle and orientation to maximize sunlight exposure, making them highly efficient in harnessing solar energy. These systems can also be equipped with tracking devices, further increasing their energy production potential.
One of the primary advantages of ground-mounted solar systems is their ability to maximize solar energy production. Unlike roof-mounted systems, which are limited by the structure and orientation of the roof, ground-mounted systems can be installed in ideal locations with optimal sunlight exposure.
Tracking Systems: Ground-mounted systems can incorporate single-axis or dual-axis trackers that adjust the angle of the panels throughout the day to follow the sun's path, increasing energy capture by up to 25-35%, according to a study by National Renewable Energy Laboratory (NREL).
Example: In the Tengger Desert Solar Park (China), one of the world’s largest solar farms, ground-mounted systems with tracking technology produce more than 1,500 MW, demonstrating the high energy yield potential of ground installations.
Ground-mounted systems are highly scalable, making them ideal for large-scale commercial and industrial solar projects. Whether you're planning a utility-scale solar farm or a community solar project, ground-mounted solar systems can be designed to accommodate thousands of panels.
Real-World Case: The Copper Mountain Solar Facility in Nevada, USA, uses a ground-mounted design to generate 802 MW of power, providing electricity to over 250,000 homes.
Additionally, ground-mounted systems can be easily expanded by adding more panels or adjusting the setup, providing long-term flexibility.
Ground-mounted systems are typically easier to maintain and repair compared to rooftop systems. Technicians have direct access to the panels without the risk of working on a sloped or elevated roof. This reduces maintenance costs and ensures quicker response times for repairs.
Fact: Solar Power World reported that ground-mounted solar farms tend to have lower maintenance costs because there are fewer obstacles, such as roof imperfections or accessibility issues.
For residential and commercial buildings with roof-mounted systems, concerns about roof damage, leaks, or structural integrity are common. Ground-mounted solar systems eliminate these risks by being installed separately from the building structure.
Statistics: According to a 2023 study by EnergySage, homes with roof-mounted solar systems report about 12% more maintenance costs over 10 years compared to those with ground-mounted systems due to potential roof damage and weathering.
While ground-mounted solar systems offer numerous advantages, proper installation is essential for ensuring maximum efficiency and longevity. Below are some expert installation tips to keep in mind:
The first step in installing a ground-mounted solar system is choosing the right location. Ideally, the site should have:
Minimal shading: Ensure that there are no trees or buildings blocking sunlight.
Stable soil: The ground should be stable enough to support the mounting structures and prevent shifting.
Accessibility: Choose a location that is easy for installation and maintenance crews to access.
Example: The Gemasolar Thermosolar Plant in Spain, a ground-mounted solar thermal plant, was built in the desert, where there’s abundant sunlight and little vegetation to block solar exposure.
Ground-mounted solar systems often require more preparation than roof-mounted systems, including leveling the land and ensuring it can support the weight of the solar panels and mounting structures.
Tip: Conduct soil tests to determine the best type of mounting system (e.g., pole mounts, ground screws, or ballast systems).
Fact: According to Solar Power International (SPI), site preparation costs for ground-mounted systems can range from $0.20 to $0.40 per watt, depending on soil conditions and the mounting type.
The type of mounting system plays a crucial role in the performance and durability of a ground-mounted system. Common mounting options include:
Fixed mounts: Panels remain at a fixed angle. Ideal for smaller installations and flat terrain.
Single-axis trackers: Panels follow the sun’s movement throughout the day. Best for regions with high solar potential.
Dual-axis trackers: More advanced tracking systems that adjust both the tilt and orientation of the panels.
Tip: If your site is in a region with varying sun angles, single or dual-axis trackers can significantly boost your system’s performance.
Ensure the panels are installed at the optimal tilt angle for maximum sunlight exposure. This angle varies depending on geographic location but typically ranges between 20° and 40°. Proper orientation is also key:
Best practice: Panels should face true south in the Northern Hemisphere and true north in the Southern Hemisphere for optimal performance.
Example: The Kurnool Ultra Mega Solar Park in India (one of the largest solar farms) uses a ground-mounted system with single-axis trackers that optimize the tilt angle throughout the day, significantly improving energy yield.
Ground-mounted solar systems, especially those utilizing sustainable practices and renewable materials, can contribute to environmental preservation.
Use of recyclable materials: Many ground-mounted racking systems are made from aluminum, steel, or other recyclable materials, reducing waste.
Agri-PV Systems: Combining solar energy with agriculture (Agri-PV) is an emerging trend that maximizes land use while supporting food production. For example, China’s Agri-PV project has shown that crops can be grown beneath solar panels, creating a win-win for both solar energy and food security.
Ground-mounted solar systems are proving to be a reliable and scalable solution for large-scale solar energy production. Their ability to maximize energy efficiency, reduce maintenance costs, and avoid potential damage to roof structures makes them an ideal choice for commercial, industrial, and utility-scale solar projects.
As the technology around solar mounting systems continues to evolve, we expect to see more innovations, such as advanced tracking systems, greater use of sustainable materials, and the integration of energy storage solutions. Ground-mounted solar systems will continue to be an essential component of the global transition to renewable energy.
