Ground-Mounted Solar Panels: Complete Guide for Homeowners

Not every property is suited for for rooftop solar. If your roof doesn't get enough sunlight, is oddly shaped, or has other limitations, you might need a different approach. For homes with a wide, sun-filled yard, a ground-mounted solar panel system can be a smart alternative.

These systems sit on the ground, giving you control over the angle and direction of your panels so they can catch the most sun throughout the day.

Ground-mounted solar panels aren't the right fit for every property, though. They require plenty of open space and stable soil to ensure a safe and effective installation. In this guide, we'll walk through how ground-mounted solar systems work, the different types available, and what to consider if they could work for your home.

1. What's a Ground-Mount Solar System?

A ground-mount solar system is exactly what the name suggests: solar panels installed on the ground on your property instead of being attached to your roof.

In this type of setup, the panels are supported by a racking structure anchored in the ground. Depending on the mounting design, the panels may sit just above the ground level or be elevated several feet to achieve the best angle for sunlight.

Some components are installed directly on the panels. For example, module-level power electronics—used to enable rapid shutdown—are typically attached to each panel. Other equipment, such as string inverters or solar batteries, can be installed farther away from the array, often inside a garage or utility area where temperatures are more controlled.

One advantage of a ground-mounted system is flexibility in the panel selection. Because the panels aren't limited by roof size or weight restrictions, larger, commercial-style solar modules can often be used.

Ground-mounted arrays can be placed anywhere on your property that receives strong sunlight and has enough open space. In most cases, it's recommended to have at least 350 square feet of unobstructured area to accommodate a typical residential system.

2. Type of Ground-Mount Solar Systems

a. Standard Ground-Mounts

Standard ground-mounts use a fixed frame to hold solar panels at a set tilt, optimized for your location's latitude and sun exposure.

Typical Foundations

• Ground screws or helical piles for soft or sandy soils.
• Driven piles for large arrays.
• Concrete piers, ballasts, or pre-cast footings for rocky or uneven ground.
• Hybrid or adjustable foundations for uneven terrain or settling areas.

b. Pole Mount

Pole mounts elevate solar panels above the ground on one or more poles, allowing greater flexibility in orientation and tilt.

Typical Foundations

• Deep concrete footings or piers for single or multi-pole support
• Ballasted bases for soft soils or temporary setups.
• Adjustable foundations to compensate for settling or uneven terrain.

3. Who Should Install Ground-Mounted Solar Panels?

a. You Have Open Land Available

If you have enough space on your property, a ground-mounted solar system can be a great solution. Open land allows solar panels to be installed in an area that receives strong, consistent sunlight throughout the day, which helps maximize energy production.

Having extra space also gives installers more flexibility when designing the system. The panels can be positioned at the optimal and orientation instead of being limited by the shape of direction of a roof. This flexibility can improve overall system performance and efficiency.

b. Your Land Has Suitable Soil and Geology

Before installing a ground-mounted solar system, it's essential to ensure your land can support a stable foundation. Just like some roofs aren't suitable for solar panels, certain types of soil may not be ideal for ground-mounted arrays. Rocky terrain, soggy oil, or unstable ground can make installation difficult or unsafe.

To confirm that your property is ready for solar, it's a good idea to consult with a solar company that can survey your property. They can evaluate the ground conditions and recommend the best approach for a secure and long-lasting installation.

4. Ground-Mounted VS Roof-Mounted Solar Panels

When choosing solar panels for your home or business, you have two main installation options: roof-mounted and ground-mounted systems. Both types allow you to harness clean energy, but they offer different advantages depending on your property and energy goals.

a. Ground-Mounted Solar Panels Advantages

Optimize Solar Energy Output

Ground-mounted solar panels give you full control of the tilt and orientation of your system. By positioning panels for maximum sun exposure, you can increase energy efficiency and generate more electricity with fewer panels. This is particularly beneficial for larger residential where performance optimization matters most.

Future-Proof Your Solar System

Ground-mounted solar panels allow for easier home upgrades or roof repairs without disrupting your solar array. Since the system is independent of your roof, you can maintain or improve your home without worrying abut taking down your panels.

Expand Your Solar Array Easily

If your energy needs grow in the future, ground-mounted systems make it easier to expand your solar array. Additional panels can be added with consistent orientation and wiring, ensuring your system maintains peak efficiency. Roof-mounted systems are often limited by available space, which make expansion more complex and less effective.

b. Roof-Mounted Solar Panels Advantages

Efficient Use of Existing Space

Installing solar panels on the roof allows homeowners to produce energy without taking up valuable yard space. For properties with limited land, rooftop systems make solar power possible without requiring additional structures on the ground.

Strong Solar Exposure

Solar panels generate the most electricity when they receive consistent sunlight throughout the day. In the United States, south-facing panels generally capture the most sunlight. If a home has a roof section facing south with minimal shading, it can provide an excellent location for solar panels without the need for additional mounting structures.

Ideal for Many Homes

Many rooftops already have the slope, direction, and elevation needed for effective solar energy production. When a roof has good sun exposure and minimal obstructions. a rooftop solar system can deliver strong performance while remaining unobtrusive and space-efficient.

Ground-mounted solar panels are a flexible and practical way to put your sunny yard to work. By setting up panels at the right angle and orientation, you can make the most of the sunlight your property receives and enjoy consistent for your home.
