Ground Mounted Solar Panels UK: Costs, Planning & Installation

When most homeowners think about solar panels, they naturally picture them on a roof. However, that's not the only way to generate renewable electricity at home.

If your roof isn't suitable, a ground mounted solar system can be an effective alternative that offers flexibility over where and how your panels are positioned.

Ground mounted systems are becoming an increasingly popular option for properties with larger gardens or unused land.

By positioning panels at an appropriate angle and orientation, they can achieve excellent solar generation while remaining easier to access for cleaning, inspections and maintenance than roof-mounted installations.

From our experience, homeowners often assume a roof is the only place solar panels can be installed.

In reality, a well-designed ground mounted system can be an excellent alternative where roof space, orientation or shading would otherwise limit solar generation.

The right solution depends on your property's layout, available land and long-term energy goals rather than one installation method being better than the other.

This guide explains how ground mounted solar panels work, what they typically cost in the UK, whether planning permission may be required and what to expect during the installation process.

What are ground mounted solar panels?

Ground mounted solar panels are installed on a supporting framework fixed into the ground rather than attached to the roof of a property.

The solar panels themselves are the same as those used in roof-mounted systems. The difference lies in the mounting structure, which is designed to support the panels securely while positioning them at an angle that helps maximise solar generation throughout the year.

For homeowners with enough available land, this approach offers greater flexibility when designing a solar installation and can sometimes overcome challenges that make roof-mounted systems less suitable.

When are ground mounted solar panels a good choice?

Ground mounted systems aren't simply an alternative to roof-mounted panels.

In some situations, they may be the more practical solution.

They can be worth considering if:

• Your roof receives limited direct sunlight.

• Trees, neighbouring buildings or chimneys create significant shading.

• Your roof has limited space.

• The roof structure isn't suitable for solar panels.

• You want greater flexibility over panel positioning.

From an installation perspective, one of the biggest advantages is that the array can often be positioned to achieve a favourable angle and orientation for solar generation.

That doesn't automatically mean a ground mounted system will outperform a roof-mounted installation.

A well-positioned roof system can generate just as much electricity, so the best option always depends on the individual property.

Before choosing a ground mounted system, it's also worth thinking about how you'll use the outdoor space in the future.

Solar panels are a long-term investment, so they should be positioned where they're unlikely to interfere with access, landscaping or future garden projects.

How much do ground mounted solar panels cost?

Ground mounted solar panels generally cost more than an equivalent roof-mounted system because the installation involves more than fitting the panels themselves.

From our experience, the biggest difference is usually the amount of groundwork required.

Two systems with the same number of panels can have very different installation costs depending on the site preparation, mounting method and the distance between the array and the property.

As a result, every quotation should be treated as property-specific. The figures below are intended as a budgeting guide rather than fixed installation prices.

*Guide prices only. Actual installation costs will vary depending on the property, equipment selected and site-specific installation requirements.

What affects the installation cost?

The solar panels themselves are only one part of the overall project. Several factors influence the final installation cost.

Ground conditions

The mounting system needs a stable foundation. Soft ground, sloping gardens or difficult soil conditions may require additional preparation before installation can begin.

Mounting system

The most suitable mounting system depends on the site itself. Factors such as soil conditions, drainage, the slope of the land and exposure to wind all influence how the array should be installed.

A detailed site assessment helps determine the safest and most appropriate solution.

Cable runs

Unlike roof-mounted systems, ground mounted arrays are often installed further away from the property.

Longer cable runs can increase both installation complexity and material costs.

System size

Larger systems require more panels, larger mounting structures and additional electrical equipment, all of which contribute to the overall installation cost.

Site access

Easy access for installers, equipment and materials can help reduce labour time, while restricted access may increase the complexity of the project.

What will an installer assess?

Before recommending a ground mounted solar installation, an installer will assess far more than the available space.

They'll typically consider:

• Available land and positioning.

• Shading throughout the day and across the seasons.

• Ground conditions.

• Distance to the property's electrical connection.

• Cable routing.

• Safe access for installation and future maintenance.

From our experience, a thorough site assessment often has a greater impact on long-term solar performance than choosing between two similar panel models. Positioning, orientation and avoiding unnecessary shading can all make a meaningful difference to how much electricity the system generates over its lifetime.

Do you need planning permission?

Planning permission isn't automatically required for every ground mounted solar installation, but the rules are generally more restrictive than for many roof-mounted systems.

Whether permission is needed depends on factors including:

• The size of the installation.

• Its height above ground level.

• Its location within the property.

• Whether the property is listed.

• Whether it's within a conservation area, National Park or another protected location.

Planning rules also differ across England, Scotland, Wales and Northern Ireland, so homeowners should always check the requirements that apply where they live before installation begins.

From our experience, planning permission is one of the first questions homeowners ask about ground mounted solar panels. Even where permission isn't required, it's worth checking whether any property-specific restrictions apply before installation begins, particularly if your home is listed or located within a protected area. A qualified installer can usually advise whether your proposed system is likely to fall within permitted development or whether a planning application is likely to be needed.

How are ground mounted solar panels installed?

Every property is different, but most ground mounted solar installations follow a similar process. Before any work begins, an installer will carry out a site assessment to confirm the most suitable location, check ground conditions and design a system that works with your property's layout.

The installation typically involves:

1. Surveying the site and confirming the system design.

2. Preparing the ground.

3. Installing the mounting framework.

4. Securing the solar panels.

5. Connecting the electrical components.

6. Testing and commissioning the system.

From our experience, the planning stage has a significant influence on long-term performance. Positioning the array to reduce shading and maximise sunlight throughout the day often makes a greater difference than simply choosing a different panel model.

Are ground mounted solar panels worth it?

Ground mounted solar panels can be an excellent investment for homeowners whose roofs aren't suitable for solar or who have enough outdoor space to install an array in an optimal position.

They offer many of the same benefits as roof-mounted systems, including:

• Lower electricity bills.

• Reduced reliance on grid electricity.

• Lower household carbon emissions.

• Greater energy independence.

The main trade-off is the higher installation cost. However, where a roof installation isn't practical, a ground mounted system can make solar generation possible when it otherwise wouldn't be.

From our experience, ground mounted systems deliver the greatest value when they overcome challenges such as limited roof space, poor roof orientation or significant shading. In these situations, they can provide an effective long-term solution that allows homeowners to benefit from solar energy when a roof-mounted installation may not be suitable.

Can ground mounted solar panels be installed with battery storage?

Ground mounted solar panels can be paired with battery storage in the same way as roof-mounted systems.

A battery stores surplus electricity generated during the day so it can be used later, helping reduce the amount of electricity imported from the grid during the evening or during periods of lower solar generation.

Battery storage isn't essential, but many homeowners consider it during the design stage because it's often easier and more cost-effective than making changes after the solar installation has been completed. Whether it's worthwhile depends on your electricity usage, how much energy you typically export and your long-term energy goals.

What maintenance do ground mounted solar panels need?

Ground mounted solar systems require relatively little maintenance, but regular checks can help keep them performing efficiently.

Homeowners should:

• Check for obvious dirt or debris on the panels.

• Keep vegetation from growing around the mounting structure.

• Look for signs of damage following severe weather.

• Arrange a professional inspection if the system's performance changes unexpectedly.

One practical advantage of ground mounted systems is accessibility. Because the panels can usually be reached safely from ground level, inspections and maintenance are often simpler than with roof-mounted installations and typically don't require specialist access equipment.

What should you consider before choosing a ground mounted system?

Ground mounted solar panels can be an excellent solution, but they're not the right choice for every property.

Before going ahead, it's worth considering:

• Whether you'll still have enough usable outdoor space.

• How visible the array will be from your home and neighbouring properties.

• Whether future landscaping plans could be be affected.

• The distance between the array and your home's electrical connection.

• Whether nearby trees could create additional shading as they mature.

From our experience, homeowners are usually happiest with their installation when the system has been designed around both their current energy needs and how they expect to use their outdoor space in the future. Taking the time to assess these practical considerations before installation can help avoid compromises later on.

Is a ground mounted solar system right for your home?

Ground mounted solar panels provide an alternative for homeowners who can't install solar panels on their roof or who have enough available land to position an array more effectively.

Although they generally cost more to install because of the additional groundwork and supporting structure, they also offer greater flexibility when it comes to panel positioning, maintenance access and designing a system around your property.

From our experience, there's no single best way to install solar panels. The right solution depends on your property's layout, available space, levels of shading and long-term energy goals.

A professional site assessment helps ensure the system is designed around your home, giving you the best opportunity to generate renewable electricity efficiently for many years to come.
