When most people picture solar panels, they imagine them fixed to a roof. But for many homes across Scotland, particularly rural properties or houses with large gardens, ground-mounted solar panels can be a very practical alternative.
Instead of placing panels on the roof, the solar array is installed on frames anchored directly into the ground. This approach allows our solar panel installers in Scotland to position the panels in the best possible direction for sunlight while avoiding roof limitations such as shading, roof angle or limited space.
At The Edinburgh Boiler Company, we design solar systems across Scotland for a wide range of properties, including homes where ground-mounted solar systems provide the most efficient setup.
How Do Ground-Mounted Solar Panels Work?
A ground-mounted solar system works in exactly the same way as a rooftop solar installation. Solar panels capture daylight and convert it into electricity through photovoltaic cells. That electricity is then routed through an inverter before powering appliances within the home.
- Solar panels capture daylight.
- Captured daylight produces DC electricity.
- Inverters convert DC electricity into usable AC power.
The difference lies in where the panels are installed and how they are positioned.
Because the system is installed on open land rather than a roof, installers can adjust the angle and direction of the panels much more precisely.
As with rooftop systems, homeowners sometimes ask about DIY solar installs — our full guide explains what can legally be done without a certified installer and where professional certification is always required.
Why Ground-Mounted Solar Systems Can Perform Well
One of the biggest advantages of ground-mounted solar systems is flexibility in positioning. With roof installations, panel direction is limited by the orientation of the building. Ground systems can be placed wherever sunlight exposure is strongest.
- Panels positioned directly toward the sun receive more daylight.
- More daylight increases electricity generation.
- Higher generation improves annual solar output.
This flexibility can be particularly useful in parts of Scotland where trees, neighbouring buildings or roof angles reduce sunlight exposure.
Cities such as Edinburgh and Aberdeen experience long summer daylight hours, often exceeding 17 hours of daylight in midsummer. Ground-mounted systems can be angled to capture sunlight across these extended daylight periods.
Types of Ground-Mounted Solar Systems
Ground-mounted solar systems are generally installed using two main frame styles.
Rack-Mounted Solar Frames
The most common design uses fixed metal frames mounted close to the ground. Solar panels are attached to these frames at a set angle designed to capture the most daylight throughout the year.
These systems are stable, reliable and commonly used for residential solar installations.
Pole-Mounted Solar Systems
Pole-mounted systems lift the solar panels higher above the ground using a central pole or support structure. Some pole-mounted arrays include solar tracking technology that adjusts the panel angle as the sun moves across the sky.
- Tracking systems follow the sun’s movement.
- Following the sun increases daylight exposure.
- Increased exposure improves solar electricity generation.
While these systems can increase efficiency, they are less common for residential installations due to higher costs. For homes where a rooftop installation is preferred, read our guide to solar panels on a metal roof to see whether your roof type is suitable and what mounting options are available
How Much Space Do Ground-Mounted Solar Panels Need?
Ground-mounted solar systems require more space than the panel area alone suggests. As a general rule, ground installations typically require around 15 to 20 square metres of clear ground per kilowatt of capacity, once row spacing, access paths and shading gaps are accounted for. A typical residential system of around 4 to 5 kW therefore usually needs between 60 and 100 square metres of usable land.
The exact amount depends on the number of panels used and how they are spaced to avoid shading between rows.
- Shading reduces solar energy production.
- Reduced production lowers system efficiency.
- Lower efficiency reduces electricity generation.
By spacing panels correctly, installers ensure the entire solar array operates at its best.
Installation Methods for Ground Solar Systems
Ground-mounted solar panels are secured using several different foundation methods depending on soil conditions and system size.
Some systems use concrete foundations to hold the frame securely in place. Others use ground screws, which are large steel anchors drilled directly into the soil. Ballasted frames can also be used in certain situations.
- Secure foundations stabilise the solar structure.
- Stable structures protect solar panels from wind.
- Protected panels maintain reliable energy production.
These mounting systems are designed to withstand the weather conditions commonly experienced across Scotland.
Planning Permission for Ground-Mounted Solar Panels
In Scotland, ground-mounted solar installations more commonly require planning permission than rooftop systems. Unlike roof-mounted panels, which can often benefit from permitted development rights, ground-mounted arrays are generally assessed by the local planning authority, who will consider factors such as the height and size of the installation, its proximity to boundaries and its visual impact on the surrounding area.
Requirements can vary between councils across Scotland, so it is always important to confirm the position with the relevant local authority before installation begins. Properties within conservation areas or on listed buildings will face additional restrictions.
Advantages of Ground-Mounted Solar Panels
Ground-mounted systems offer several practical benefits.
Because the panels are not attached to the roof, there is no risk of roof damage during installation. The panels are also easier to access for cleaning and maintenance since they are installed at ground level.
- Flexible positioning allows installers to orient panels for optimal sunlight exposure.
- Maintenance access is simpler than rooftop systems.
- Larger arrays can sometimes be installed where roof space is limited.

Things to Consider Before Installing Ground Solar
While ground-mounted solar systems offer flexibility, they also require more space and additional groundwork during installation. Trenching may be required to connect the solar array to the property’s electrical system.
Ground-mounted systems may also cost slightly more than rooftop installations because of the mounting frames and foundations involved.
Security can also be a consideration in open areas where equipment may be more visible or accessible.
Do You Need Planning Permission for a Ground-Mounted System?
Ground-mounted arrays are more likely to trigger planning rules than a standard roof install. See solar panel planning permission in Scotland.
Ground Solar Installation with The Edinburgh Boiler Company
At The Edinburgh Boiler Company, we design solar panel systems specifically for homes across Scotland. Our engineers assess land availability, sunlight exposure and system layout to determine whether a roof-mounted or ground-mounted solar installation is the best option.
Ground-mounted systems can be particularly effective for rural homes, properties with large gardens, or buildings where roof conditions make rooftop installation less suitable.
With careful planning and professional installation, ground-mounted solar panels can provide reliable renewable electricity generation for many years.
