When planning a solar energy system, one of the first decisions to make is whether to install your panels on the roof or on the ground. Ground-mounted solar systems offer flexibility in terms of placement and design, making them ideal for properties with ample open space. However, many people wonder about the cost: Is ground mounting more expensive than rooftop solar?
Average Cost of Ground-Mounted Solar Systems
The cost to ground mount solar panels typically ranges from $1.50 to $2.50 per watt, depending on the project size, location, site conditions, and the type of mounting system used. For a standard 5 kW system, this translates to roughly $7,500 to $12,500 before incentives.
By comparison, rooftop systems often cost a little less due to lower material and labor needs for structural support. However, ground-mounted setups offer advantages that can justify the slightly higher upfront cost.
What Factors Affect the Cost?
Several variables influence the final cost of a ground-mounted solar system:
- Mounting System Type: Fixed-tilt systems are usually more affordable, while adjustable or tracking systems (which follow the sun) are more expensive but can significantly boost energy production.
- Site Preparation: Ground clearing, leveling, and trenching for cabling can add to the cost, especially if the land is rocky or sloped.
- Foundation: Depending on the soil condition, foundations may involve concrete footings, ground screws, or piles. Companies like SIC Solar offer engineered ground screw systems that simplify installation and reduce concrete use, which helps control costs.
- Labor: Ground mounting generally requires more labor than roof installations, especially for digging and wiring.
- Permitting and Inspection: These may be more complex and costly for ground-mounted systems due to additional structural requirements.
Advantages That Offset the Cost
Despite the slightly higher upfront price, ground-mounted systems offer compelling benefits:
- Optimal Orientation and Tilt: Panels can be perfectly angled for maximum sun exposure, improving energy yield.
- Easier Maintenance: Ground access makes cleaning and repairs safer and more convenient.
- Scalability: Easier to expand in the future compared to roof-based systems.
- No Roof Limitations: Ideal for homeowners whose roofs are shaded, small, or structurally weak.
How SIC Solar Supports Efficient Ground-Mounted Installations
SIC Solar, a professional manufacturer of photovoltaic mounting systems, offers a range of cost-effective and durable ground mounting solutions. Their systems are designed for various terrain conditions and support both fixed and adjustable angles.
The use of pre-assembled parts and ground screws reduces installation time and labor costs. By choosing a supplier like SIC Solar, project developers can balance quality and affordability, ensuring long-term reliability without excessive upfront expense.
The cost of ground-mounted solar panels varies based on several factors but generally falls in the range of $1.50 to $2.50 per watt. While this can be more than rooftop systems, the long-term advantages—including improved performance, easier maintenance, and expandability—make it a worthwhile investment for many property owners. Partnering with experienced manufacturers like SIC Solar ensures you’re getting robust, efficient mounting systems that deliver both value and performance.
