Ground Mounted Solar Panels: Comprehensive Guide 2025

Ground mounted solar panels offer higher efficiency compared to roof-mounted systems because they can be optimally angled without the constraints of a roof. This setup also allows for the installation of bifacial solar panels, which convert more sunlight into power. These panels typically operate cooler than roof-mounted panels, maintaining efficiency for longer periods. However, they may face obstacles such as buildings or trees that can block sunlight. If your property includes a significant amount of land, ground-mounted solar system could be a great option. With sufficient sunlight exposure, these panels can provide a quicker return on investment.

This guide will help you understand the costs, space requirements, and benefits of ground-mounted solar panels, compared to roof-mounted options.

What are Ground-Mounted Solar Panels?

Ground-mounted solar panels are installed on the ground rather than on a roof. Though commonly used in solar farms, they are also suitable for domestic installations. Panels can be mounted on a metal frame or a single pole, driven into the ground or anchored with concrete for stability. Pole-mounted panels can include a solar tracking system that adjusts the panel’s angle based on the sun’s position, increasing efficiency by 20% to 35%. However, these systems are costly, around £2,500, and consume some electricity to operate. Additionally, ground-mounted panels are ideal for bifacial solar systems, which produce 10-30% more electricity than traditional panels, though they come with a higher initial cost.

Cost of Ground-Mounted System

In the UK, Boxergy offer a 10 solar panel system for only £3,999 (fully installed).  Ground-mounted systems cost between £7,500 and £16,000 due to additional materials and installation time. These systems require a custom-built support structure and longer wiring, often trenched to avoid environmental damage. Innovative solutions like ‘solar trees’ in public spaces can cost as much as £63,000 each.

Space Requirements for Ground-Mounted Solar Panels

For a three-bedroom house, about 50 square meters of ground space is needed to meet energy needs with ground-mounted panels. Smaller spaces can still benefit from supplementary ground-mounted panels, either supporting roof panels or powering smaller structures like sheds. A typical 350-watt solar panel measures about two meters by one meter, and a three-bedroom house generally needs around ten panels (20 square meters). Additional space is required to prevent shading from the house.

Proximity to Property

Ground-mounted panels don’t have to be close to the house, but increased distance raises installation costs due to the need for longer, thicker wiring to prevent voltage drops.

Selling a House with Ground-Mounted Solar Panels

Solar panels could increase a property’s value thanks to lower electricity bills and a reduced carbon footprint. However, ground-mounted systems reduce available land, which might offset the value increase.

Ground-Mounted vs. Roof-Mounted Solar System

Ground-mounted panels are placed on the ground, allowing optimal sun exposure and ease of maintenance. They are ideal for properties with ample land but unsuitable roofs. Roof-mounted panels use otherwise unused roof space, integrating seamlessly and providing natural cooling to the building. However, they can be harder to maintain and might be shaded by nearby structures.

Ground-Mounted Solar Panels: Pros and Cons

Pros:

• Easier to angle and direct for maximum sunlight.
• More efficient due to better ventilation.

Cons:

• Higher cost.
• Need for significant ground space.
• Potential shading from vegetation or structures.

Roof-Mounted Solar Panels: Pros and Cons

Pros:

• Cheaper installation.
• Utilises unused roof space.
• No planning permission needed (except in special areas).

Cons:

• Harder to maintain.
• Potential shading issues.
• Planning Permission
• Ground-mounted systems larger than nine square meters require planning permission, as do installations on listed buildings or within conservation areas.

Suitability for Your Property

Ground-mounted solar panels are suitable for properties with extensive land and unsuitable roofs. They can generate more electricity due to their optimal positioning but are not ideal for properties with limited space. For those with land constraints, alternative solutions like wall-mounted panels might be considered.

Ultimately, whether on the roof or ground, solar panels are an effective way to reduce energy bills and utilise green energy. If your property allows for more ground-mounted panels, they could be a better investment. Ready to install solar panels? Contact us today.
