This in-depth guide will explore the full scope of ground mounted solar panel systems — what they are, their benefits, types, installation, costs, and the vital role they play in achieving net-zero emissions.
What is a Ground Mounted Solar Panel System?
A ground-mounted solar power system is a type of solar panel installation on your property, installed at ground level, rather than on the roof of your house. The panels are typically positioned a few inches to several feet above the ground, with module-level power electronics attached for rapid shutdown. Other system components can be placed away, allowing temperature-sensitive equipment like string inverters and solar batteries to be stored in your garage.
Ground-mounted installations allow for the use of solar panels of any size, including large commercial modules with 72 cells or more. They can be installed anywhere with good sun exposure and sufficient open space, typically requiring a minimum of 350 square feet. Ground-mounted solar panels are also known as backyard solar panels, free-standing solar panels, and ground-mount PV systems.
Key Components:
- Installation Flexibility: These systems can be placed in various locations with sufficient sunlight exposure, making them ideal for areas where rooftop installations are impractical.
- Optimal Sunlight Exposure: Ground-mounted panels can be oriented and tilted to maximize solar energy absorption, enhancing overall system efficiency.

By allowing for precise positioning and adjustment, ground mounted systems can significantly increase the amount of solar energy captured and converted into electricity.
2. Improved Accessibility
Ground mounted solar panel systems offer easier access for maintenance and cleaning compared to rooftop systems. Since the panels are installed at ground level, routine inspections, cleaning, and repairs can be carried out more conveniently. This accessibility reduces the need for specialized equipment or safety measures often required for rooftop installations, making it easier to maintain system performance over time.
3. Design Flexibility
The flexibility of ground mounted solar panel systems is another notable benefit. These systems can be customized to fit various land shapes and sizes, and they can incorporate tracking systems that follow the sun’s movement. By allowing for dynamic adjustments, ground mounted systems ensure that solar panels remain optimally positioned throughout the day, maximizing energy production and overall system efficiency.
4. Reduced Risk of Roof Damage
By opting for ground mounted solar panel systems, property owners can avoid potential roof damage. Rooftop solar panels, if not installed or maintained properly, can lead to leaks or structural issues. Since ground mounted panels are not attached to the building, this risk is eliminated, providing peace of mind and protecting the integrity of the property.
5. Aesthetic Advantages
For properties where the appearance of rooftop solar panels might be undesirable, ground mounted solar panel structures offer an aesthetically pleasing alternative. These systems can be placed in less visible areas of the property, such as open fields or unused land, preserving the visual appeal of the building while still benefiting from solar energy.
6. Scalability
Ground mounted solar panel systems are highly scalable, making them ideal for both small and large-scale solar projects. Whether you are looking to install a modest number of panels or develop a large solar farm, ground mounted systems can be easily expanded to accommodate increasing energy needs. This scalability ensures that the system can grow with your energy demands.
