Looking for a suitable option among ground-mounted or rooftop solar panels? In Ireland, the shift towards renewable energy is gaining momentum, with solar energy emerging as a top choice for both homes and businesses looking to cut costs and reduce their carbon footprint. 

When it comes to installing solar panels, the decision between ground-mounted and rooftop options is more than just a matter of preference—it's about finding the best fit for your specific needs and property layout. Each type has its unique set of benefits and considerations that can significantly influence your energy production and savings. 

In this blog, we will help you to find out if ground-mounted or rooftop solar panels are right for you. Compare environmental impact, sustainability, and efficiency of both systems.

Want to find out which solar panel installation is right for you? Let’s start exploring the differences to help you make an informed choice.

What Should You Understand About Ground-Mounted Solar Panels?

By understanding the features and benefits of ground-mounted solar panels, you can better assess if they are the right choice for your energy needs.

What are ground-mounted solar panels?

Ground-mounted solar panels are installed directly on the ground rather than on a roof. These systems are often set up in open spaces where they can be oriented and tilted to capture the maximum amount of sunlight throughout the day.

This flexibility in positioning allows for optimal solar energy production, making them a great choice for properties with ample land.

Benefits of ground-mounted solar panels

One of the main advantages of ground-mounted solar panels is their efficiency. Because they can be adjusted for the best angle and orientation, they often generate more electricity compared to rooftop panels.

Additionally, they don’t require drilling into your roof, which can preserve the integrity of your building. Ground-mounted systems are also easier to access for maintenance and cleaning, ensuring they operate at peak performance.

What Should You Understand About Rooftop Solar Panels?

Understanding rooftop solar panels is crucial for determining if this installation type suits your property’s needs and constraints. 

What are rooftop solar panels?

Rooftop solar panels are installed directly on the roof of a building, whether it’s a home, business, or other structure. They are mounted using specialised racks that ensure the panels are securely attached and positioned to capture maximum sunlight. 

Benefits of rooftop solar panels

One of the primary advantages of rooftop solar panels is their space efficiency. Since they are installed on the roof, they don’t require any additional land, making them ideal for urban areas or properties with limited yard space.

Additionally, rooftop panels often benefit from fewer obstructions, such as trees or buildings, allowing for optimal sunlight exposure. This can enhance energy production and maximise the return on your investment.

How Can We Compare Ground-Mounted & Rooftop Solar Panels by Efficiency?

Efficiency of ground-mounted solar panels

Ground-mounted solar panels often offer higher efficiency compared to their rooftop counterparts. This is because they can be positioned to capture the maximum amount of sunlight throughout the day, with optimal orientation and tilt angles.

Ground-mounted systems are not limited by the angle and direction of your roof, which means they can consistently generate more energy, especially in properties with large open spaces.

Efficiency of rooftop solar panels

Rooftop solar panels, while slightly less flexible in terms of positioning, still provide substantial energy savings. They are installed directly on the roof, which often receives ample sunlight. However, the efficiency can be affected by factors such as roof orientation, angle, and any shading from nearby trees or buildings.

Despite these limitations, rooftop installations are highly effective for urban settings with limited space.

By understanding the efficiency and cost implications of both ground-mounted and rooftop solar panels, you can better assess which option aligns with your financial and energy goals. 

How Can We Compare Ground-Mounted & Rooftop Solar Panels by Environmental Impact and Sustainability?

Ground-mounted solar panels

Ground-mounted solar panels have a significant environmental impact due to the land they occupy. These installations often require clearing vegetation and altering the landscape to make space for the panels.

However, they offer the advantage of optimal positioning. Additionally, ground-mounted systems can be placed in underutilised areas, such as fields or brownfield sites, which can offset their land use impact.

Rooftop solar panels

Rooftop solar panels have a lower environmental footprint regarding land use since they utilise existing structures. By placing panels on roofs, you avoid the need to clear additional land, making this option more sustainable in urban and suburban settings.

However, they might be less efficient than ground-mounted systems if the roof’s orientation or angle is suboptimal for sunlight capture.

When choosing between ground-mounted and rooftop solar panels, consider the specific environmental impacts and sustainability benefits of each option. 

Conclusion

Choosing between ground-mounted and rooftop solar panels depends on your property size, roof condition, and future energy needs. Ground-mounted systems offer flexibility and ease of maintenance, while rooftop installations are space-efficient and typically face fewer regulatory hurdles. 

Both options can significantly reduce your energy bills and carbon footprint. To determine the best solution for your specific situation, consult with a professional.

Frequently Asked Questions

What are the main benefits of ground-mounted solar panels?

Ground-mounted solar panels offer flexibility in placement and orientation, making it easier to optimise them for maximum solar energy absorption. They are also easier to access for maintenance and repairs. However, they require more space and can have higher initial costs due to the need for additional mounting structures​​.

What are the primary advantages of rooftop solar panels?

Rooftop solar panels are cost-effective as they utilise existing roof space, avoiding the need for additional land. They are less intrusive visually and can be easier to install in residential areas where space is limited. Rooftop installations also tend to have simpler permitting processes compared to ground-mounted systems​​​.

How does installation differ between ground-mounted and rooftop solar panels?

Ground-mounted panels require a suitable open space and may involve more complex installation and permitting due to the need for ground preparation and structural supports. Rooftop panels, on the other hand, require a roof in good condition and suitable for bearing the weight and installation of panels. They can be more challenging to maintain due to their less accessible location​​.

Can the choice between ground and rooftop solar panels affect maintenance?

Yes, maintenance accessibility is easier with ground-mounted panels, which can be reached without ladders or special equipment, making cleaning and repairs straightforward. Rooftop panels, conversely, may require professional services for maintenance due to their less accessible locations​​.

Do both types of installations affect the property apperance?

Yes, appearance play a role in choosing the type of installation. Rooftop panels can be less visible depending on roof orientation and home design, potentially being hidden from street view. Ground-mounted panels may be more visible but offer the flexibility to be placed in less noticeable locations on larger properties​​.

Are there long-term benefits to either type of solar panel installation?

Both installations offer long-term energy savings, but ground-mounted systems may provide slightly higher energy output due to optimal positioning. Rooftop systems save space and can extend the life of roofing materials by protecting them from the elements​.
