Ground-Mounted Solar: A Viable Alternative

The transition to renewable energy, especially solar power, has been gaining momentum. According to the U.S. Energy Information Administration (EIA), solar power generation in the U.S. grew by nearly 30% in 2020 compared to 2019, and the adoption of solar energy continues to expand across the country. Not every home is ideally suited for traditional rooftop solar panels. Factors like roof shading, structural limitations, or personal preference for not installing panels on your roof can present challenges. This is where ground-mounted solar systems come into play, offering an excellent alternative for homeowners looking to harness solar energy while bypassing the constraints of a traditional rooftop installation. Ground-mounted solar panels are becoming an more popular solution for those seeking flexibility and maximum energy efficiency without compromising aesthetics or performance.

Ground-mounted systems are typically installed on open land, providing the opportunity to position the panels at prime angles for sun exposure, avoiding shading issues that can affect roof-mounted systems. They also allow for easier maintenance, because the panels are more accessible compared to rooftop installations. Whether your property has the necessary space for a ground-mounted system or you’re looking for a system that offers flexibility in placement, ground-mounted solar solutions can help you take full advantage of renewable energy without the limitations of a rooftop installation. As solar energy technology continues to evolve, ground-mounted systems are expected to play a role in meeting the growing demand for sustainable, clean energy solutions.

Importance of Proper Sun Exposure

For effective power production, solar panels require unobstructed access to the sun’s rays. This is why the ideal location for solar panels is a south-facing roof with little to no shade. But, if your roof is shaded or has an unconventional layout, this ideal situation might not be achievable. Here is where the question arises, “What do I do if my roof is too shaded for solar panels?”

Ground-Mounted Solar: A Viable Alternative


In situations where rooftop solar installation is not a viable option or is simply not preferred, ground-mounted solar systems provide an excellent alternative. These systems involve installing solar panels directly on the ground rather than on a roof, offering flexibility and advantages that rooftop installations may not be able to provide. Ground-mounted systems are especially useful in cases where roof space is limited, the roof is shaded, or homeowners prefer not to alter their roof structure. Here are several reasons why ground-mounted solar systems could be the ideal choice:

  • Optimal Positioning: One significant advantage of ground-mounted systems is that they can be positioned perfectly south-facing in a shade-free area to maximize production.
  • Ease of Maintenance: Ground-mounted systems are generally easier to clean and maintain as they are more accessible than roof-mounted panels.
  • Customizable Tilt and Orientation: Ground-mounted systems allow for the adjustment of tilt and orientation to maximize sunlight exposure, thereby increasing efficiency.
  • Space Efficient: For property owners with ample land, ground-mounted systems can be a great way to utilize unused space.

For homeowners looking to invest in solar energy but facing challenges with traditional roof-mounted systems, ground-mounted solar panels offer an adaptable and highly efficient solution.

Factors Influencing Ground-Mounted Solar Installation

While ground-mounted solar can be a great option, there are a few additional factors to consider:

  • Additional Costs: Ground-mounted systems typically involve extra expenses, such as trenching and the structure or framing itself.
  • Space: You will need enough unshaded land to install a ground-mounted solar array.
  • Regulations: Local zoning rules, HOA regulations, or other restrictions might limit the installation of ground-mounted solar systems.

Distance Limitations for Ground-Mounted Systems

Another consideration when installing a ground-mounted solar system is the distance between the panels and your home, especially when the system is located far from the electrical meter. In most cases, it becomes challenging to install a ground-mounted system more than 300 feet away from the home due to potential voltage drop issues. As electricity travels over longer distances, it loses energy, which can result in a decrease in the efficiency of the system. This is known as voltage drop, and it can impact the overall performance of your solar installation, potentially leading to lower energy output.

Along with voltage drop concerns, the distance between the ground-mounted system and your home can also increase the complexity and cost of the installation. Longer cable runs require more materials, and the need for trenching to lay the cables can increase labor costs and time required for installation. These factors can add expenses to the project, especially when distances are extended beyond 300 feet.

When planning a ground-mounted system, it’s important to consider the location of the panels and the associated costs of the electrical connection. For systems that require long cable runs, it may be necessary to use thicker wires to minimize voltage loss, which can further raise the overall cost of the project. It’s advisable to work closely with a professional solar installer who can help assess the best location for the system and ensure that the electrical connection remains efficient without adding unnecessary costs or reducing the performance of the solar panels.

Approval and Design Considerations for Ground-Mounted Systems

The installation time frame for a ground-mounted solar system is typically longer than that of a rooftop system due to various factors that need careful consideration and planning. While roof installations can be more straightforward, ground-mounted systems require additional steps to achieve proper placement and compliance with local regulations. These factors include:

Obtaining Permits: Before installation begins, securing the necessary permits from local authorities is crucial. Depending on your location, these permits may involve general construction approvals and specific solar installation permits. It’s important to work with an experienced installer who can navigate these requirements and expedite the approval process.

Land Surveys: Conducting a land survey is an essential step to determine the best location for the solar array. This survey helps identify the land’s topography, potential shading issues, and ensures there is enough space for the system. The survey also plays a role in determining how to orient the panels for maximum efficiency.

Geotechnical Reports: A geotechnical report evaluates the soil composition and ground conditions where the solar panels will be installed. This report determines if the soil can support the weight and structure of the mounting system. It also helps identify whether any special foundations like piers or footings, are required to secure the solar array.

Zoning and HOA Regulations: It’s essential to check local zoning regulations and HOA rules before proceeding with a ground-mounted system installation. Zoning laws may restrict where solar panels can be placed on your property, and homeowner associations may have specific guidelines for aesthetics, structure height, and system visibility. Understanding these regulations ahead of time can save you from delays and additional costs.

Structural Design: Selecting the right racking and mounting system is critical for the stability and longevity of the solar array. The structural design must be tailored to the site’s specific conditions, including soil type and land slope, to make sure the system will withstand weather elements and remain securely anchored for years.

By addressing all these factors thoroughly, a ground-mounted solar system installation can proceed smoothly and effectively. While the process may take longer than a rooftop installation, these considerations are necessary to make sure the system is well-executed and durable.

To Ground Mount Or Not?

Ground-mounted solar systems provide a perfect solution for homeowners who have a shaded roof or prefer not to install solar panels on their roof. Despite the additional cost and installation time, these systems offer excellent efficiency due to their optimal positioning and exposure to sunlight. With solar energy continuing to grow as a significant renewable energy source, ground-mounted solar systems are a worthwhile consideration for many homeowners.
