Quick Answer
Pole-mounted solar systems are generally more expensive than ground-mounted systems, with prices ranging from $3 to $5 per watt, compared to $2 to $3.50 per watt for ground-mounted systems.
Pole-Mounted System Costs
Pole-mounted solar systems are typically more expensive due to the cost of the structural support, such as steel or aluminum poles, and the necessary electrical connections and wiring. A typical pole-mounted system might require a 3- to 4-inch steel pipe, with a cost ranging from $500 to $1,000, depending on the length and material. Additionally, the mounting hardware, such as clamps and brackets, can add another $200 to $500 to the overall cost.
Ground-Mounted System Costs
Ground-mounted systems, on the other hand, can be more cost-effective, especially for larger arrays. A ground-mounted system can be installed using a racking system that is attached to concrete footings or driven into the ground, reducing the need for expensive pole structures. The cost of the racking system can range from $1 to $2 per watt, depending on the quality and type of materials used.
Installation Considerations
When choosing between a pole-mounted and ground-mounted system, it’s essential to consider the installation site and the local building codes. Pole-mounted systems are often more suitable for areas with limited space or existing structural support, such as rooftops or existing utility poles. Ground-mounted systems, however, can be more suitable for larger properties or areas with more space available. It’s also essential to consult local authorities to ensure compliance with building codes and regulations.
