Shading the Way to Savings: The Advantages of Solar Panel Carports Over Roof-Mounted Solar Panels

Solar Carports

In recent years, solar energy has gained immense popularity as a sustainable and eco-friendly source of power. As more individuals and businesses look to harness the benefits of solar power, the choice between installing rooftop solar panels or solar panel carports has become a significant decision. Solar panel carports offer several distinct advantages over traditional rooftop installations, making them an increasingly attractive option for those looking to invest in clean energy. In this article, we will explore the numerous benefits of solar panel carports and why they may be the right choice for your energy needs.

Efficient Land Use

One of the primary advantages of solar panel carports is their efficient land use. Rooftop solar installations require valuable rooftop space that could potentially be used for other purposes. Solar carports, on the other hand, make use of underutilized or open parking areas. By installing solar panels over parking lots, you can maximize the utility of the space without sacrificing valuable real estate.

Shaded Parking

Solar carports offer the dual benefit of providing shaded parking spaces. Not only do they generate clean energy, but they also shield vehicles from the scorching sun or adverse weather conditions. This additional amenity can be a selling point for commercial properties and a significant convenience for employees and customers.

Enhanced Aesthetics

Solar panel carports can be designed to complement the architecture and aesthetics of a property, enhancing its overall appeal. These structures can be customized to blend seamlessly with the existing design, making them a visually pleasing addition to your property.

Reduced Cooling Costs

The shading effect of solar carports can significantly reduce the cooling costs of buildings beneath them. By providing a barrier to direct sunlight, solar carports help maintain a cooler environment in the covered areas. This can result in lower energy bills and a more comfortable workspace.

Easy Maintenance

Solar carports are easier to maintain compared to rooftop solar panels. Accessing and servicing solar panels on carports is typically more straightforward because they are at ground level. Roof-mounted systems may require more complex maintenance procedures, which can be costlier and more time-consuming.

Faster Installation

Installing solar carports is often faster and less disruptive than rooftop installations. Since solar carports are constructed over open spaces like parking lots, the installation process can be completed without interfering with daily operations. Rooftop installations may require additional structural assessments and reinforcement, which can extend the installation timeline.

Maximizing Solar Exposure

Solar panel carports can be positioned to maximize exposure to the sun. This strategic placement ensures optimal energy production throughout the day, as the panels can be oriented and tilted to capture the most sunlight. Rooftop installations are often limited by the orientation and angle of the roof.


Solar panel carports are highly scalable. You can expand your solar capacity by adding more carports as your energy needs grow. This flexibility is particularly advantageous for businesses with evolving energy demands.


Costs relative to Roof mounted solar

The cost of solar carports versus rooftop solar installations can vary based on a number of factors, including location, size, materials used, and project complexity. Here are some key considerations to help you understand the cost differences between solar carports and rooftop solar systems:

Solar Carports: Solar carports are typically more expensive to install than rooftop solar panels because they require additional structural support, such as steel or aluminium framework to hold the solar panels above the parking area. The cost of these structures can significantly increase the overall cost. Typically £1,500 to £3,000 per kW of solar, the cost of a roof and then the solar equipment on top.

Rooftop Solar: Rooftop solar installations are generally more straightforward and less expensive because they don’t require as much structural work. They are mounted directly on your roof. Typically £800 to £1,500 per kW of solar.

Size of the System: The size of the solar system you install will greatly impact the cost, regardless of whether it’s on a carport or a rooftop. Larger systems with more solar panels will naturally be more expensive.

Materials and Design: Solar carports may use more expensive materials like steel or aluminium to support the panels, which can increase costs. Rooftop solar installations generally use standard racking systems that are less costly.

Location and Sunlight: The amount of sunlight your location receives affects the efficiency and cost-effectiveness of the solar system. If your carport location has better sun exposure, it might offset some of the extra costs.

Labour Costs: Labor costs for the installation may vary depending on the complexity of the project and local labour rates.

Incentives and Rebates: The availability of government incentives, tax credits, and rebates can significantly reduce the cost of both solar carports and rooftop solar systems.

Aesthetics and Space: Solar carports can provide shaded parking spaces, potentially enhancing property value and aesthetics, which may be a consideration for some property owners.

Maintenance and Lifespan: Both solar carports and rooftop solar panels require maintenance, but carports may have slightly higher maintenance costs due to their exposed structure.


Solar panel carports offer a range of advantages over rooftop solar installations. They make efficient use of land, provide shaded parking, enhance property aesthetics, reduce cooling costs, and are easier to maintain. Additionally, they can be installed more quickly and with greater flexibility in mind.

By choosing solar panel carports, property owners can harness the power of the sun while enjoying a host of practical benefits that extend beyond sustainable energy production. It’s a wise investment that not only benefits the environment but also improves the functionality and appeal of your property.

In summary, solar carports are typically more expensive to install than rooftop solar systems due to the additional costs associated with the structural support and the potential benefits, such as shaded parking. However, the overall cost difference can vary depending on the specific circumstances of your project.

It’s essential to obtain quotes from multiple solar installers, consider available incentives, and evaluate the long-term cost savings and benefits of each option to determine which is the best fit for your needs and budget.
