What Are Ground Mounted Solar Panels?
Ground mounted solar panels are solar energy systems installed directly on the ground, rather than the roof. While they are commonly used in solar farms, they are also ideal for domestic and commercial installations, especially if you have high energy usage and ample outdoor space.
These panels are mounted on metal frames or poles anchored into the ground. More complex systems can include solar trackers which automatically adjust the panel angle to follow the sun, increasing efficiency by 20-25%.
Ground mounted panels are also the perfect solution for bifacial solar panels, which capture the sunlight on both sides, producing 10-30% more electricity than standard solar PV panels. Although these systems have higher upfront costs, their increased efficiency can accelerate your return on investment.
How Much Do Ground Mounted Solar Panels Cost?
A typical roof mounted solar system for a three-bedroom house costs £5,500-£7,000. Ground mounted solar panels are generally 25-35% more expensive, costing £8,000 to £15,000, depending on system size, equipment and installation complexity.
The higher cost is due to the complexity of ground mounted installations, and the more labour intensive process. The support frame is built from scratch, with additional materials required for stability and anchoring. Trenches and longer wiring is required to connect the solar panels to your property.
How Much Space Do Ground Mounted Solar Panels Need?
The space required depends on the size of your solar system and your usage. A typical solar panel measures around 2m by 1.15m. An average three-bedroom home needs 20-30 square meters for full energy needs.
Ground mounted panels don’t have to be right next to your property, but longer distances increase installation costs due to thicker, longer wiring needed to prevent energy loss.
Ground Mounted vs Roof Mounted Solar Panels
Ground Mounted Solar Panels:
- Pros: optimal tilt and direction, higher efficiency, easier to maintain, ideal for properties with shaded or unsuitable roofs
- Cons: higher installation costs, more prone to shading and accidental damage, requires sufficient land.
Roof Mounted Solar Panels:
- Pros: saves ground space, lower installation costs, integrated with property aesthetic and provides natural roof shading.
- Cons: harder to access for maintenance, roof orientation and shading can reduce efficiency.
Ground mounted panels are ideal if you want maximum energy production and flexibility in panel placement. Ground mounted panels also allow for larger arrays and can cover higher energy use. They are also more practical if you have a property that is in a conservation area or has listed building status.
Do I Need Planning Permission for Ground Mounted Solar Panels?
Ground mounted solar systems larger than 9 square metres (four to five panels) require planning permission. Planning permission is also required if you live in a conservation area, near a World Heritage Site or if your property is listed.
You can check regulations and apply for permission via the Planning Portal, or ask our experts at SolarTherm UK for advice.
