5 Key Considerations Before Installing a Solar Ground-Mount

Are you thinking about installing a solar energy system?

If so, congratulations on taking the first step towards gaining control of your electric bill and shrinking your carbon footprint! This one investment can bring decades of free electricity, substantial tax savings, and help you make a significant difference in the environment and your financial future. By choosing to install a solar energy system, you are not only reducing your dependence on non-renewable energy sources but also contributing to a more sustainable and eco-friendly world.

However, before you dive in, you’ll want to determine what kind of solar system you should install. The two primary options are a roof-mount system and a ground-mount system, each with its own set of advantages and disadvantages. The best choice will ultimately depend on your specific circumstances and needs.

A roof-mount system involves installing solar panels directly on the roof of your home or building. This is the most common type of installation and is generally more cost-effective because it utilizes existing structural support. Roof-mount systems are less intrusive and can blend in with the architecture of your home, making them aesthetically pleasing. They also require less land, which is particularly beneficial in urban areas where space is limited. Additionally, roof-mounted panels are often subject to fewer zoning restrictions and may be easier to permit.

On the other hand, a ground-mount system involves installing solar panels on a freestanding structure on the ground. This option is ideal if your roof is not suitable for solar panels due to age, condition, or orientation. Ground-mount systems allow for optimal placement and orientation of the panels, which can maximize energy production. They are also easier to access for maintenance and cleaning, and you can install a larger system if you have the available land. However, ground-mount systems can be more expensive due to the additional materials and labor required to build the support structure. They may also face more stringent zoning and permitting requirements, especially in residential areas.

Before making a decision, consider factors such as the condition and orientation of your roof, the amount of available land, your budget, and local regulations. Consulting with a professional solar installer can provide valuable insights and help you choose the best option for your specific situation. By carefully evaluating these factors, you can ensure that your solar energy system meets your needs and provides long-term benefits for both your wallet and the environment.

If you’re thinking about installing a ground-mount system, there are five things you need to know first.

1. There are Two Types of Ground-Mount Systems

Standard-Mounted Panels

When you think of ground-mounted solar panels, an image of a standard ground-mount system is probably what pops into your mind. Metal poles are drilled deep into the ground with a post pounder to securely anchor the system. Then, a framework of metal beams is erected to create the supporting structure on which the solar panels are installed. Allowances do need to be made for the additional space required, as panels need to be spaced away from any parapet or perimeter walls to avoid them shading one another. Also, flat roof systems tend to rely on ballast to secure your panels against wind or stormy weather, which can increase the load-bearing demands made of the roof. Many also find that automatic panels, which adjust their angle according to the sun’s position, produce a significantly improved energy return.. All in all,you can contact us, as long as you work with a professional installation engineer, you’ll be able to create a solar array that operates effectively, whatever your specific needs.

The sun doesn’t stay in one place throughout the day or the year. That means a system installed at a fixed angle (standard-mounted system) will produce less energy than a system that is dynamic and adjusts the tilt along with the sun’s daily and yearly movement.

2. Ground-Mount Solar Systems Are Typically More Expensive

Compared to a roof-mounted solar system, ground mounts will most likely be the more expensive option, at least in the short term.

Ground-mount systems require more labor and more materials. While a roof mount still has a racking system to hold the panels in place, its main support is the roof on which it’s installed. With a ground-mount system, your installer needs to first erect the sturdy support structure with steel beams drilled or pounded deep into the ground.

But, while the installation cost may be higher than a roof mount, that doesn’t mean it’s the best option long term. With a roof mount, you’re at the mercy of your roof, which may or may not be suitable for solar. Some roofs may not be able to support the additional weight of a solar system without reinforcements, or you may need to replace your roof. Additionally, a north-facing roof or a heavily shaded roof can severely reduce the amount of electricity your system generates. These factors could make a ground-mounted solar system more appealing than a roof-mounted system, despite the increased installation cost.

3. Ground-Mounted Solar Panels May Be Slightly More Efficient

Compared to a roof mount, a ground-mounted system may produce more energy per watt of solar installed.

Solar systems are more efficient the cooler they are. With less heat present, there will be less friction as the energy transfers from the solar panels to your home or business.

4. You’ll Have to Set Aside a Portion of Land for the Ground-Mount System

While ground-mount systems allow you to choose the best place to install your solar system in regards to production, you need to dedicate that area to the solar system.

Especially for farmers, giving up land means giving up income. In some cases, you can install a ground-mounted system that’s several feet higher off the ground. This can allow the clearance required for growing crops underneath the panels. However, this will come with an added cost, which should be weighed against the profit of those crops.

5. Ground Mounts Are Easier to Access – Which is Both Good and Bad

Ground-mounted panels will be easier to access over panels installed on rooftops. This can come in handy should you need maintenance or repairs for your panels. It’ll be easier for solar technicians to access ground mounts, which can help keep costs down.

That said, ground mounts also make it easy for unauthorized people and animals to access your system. Anytime there is intense pressure on the panels, whether it be from climbing on them or hitting them, it can accelerate the degradation of your panels, and curious animals may even chew on wiring.

Oftentimes, solar owners will install a fence around their ground mount system to keep out unwanted visitors. In fact, this may be a requirement, depending on your system’s size and the local rules. The need for a fence will be determined during the permitting process or during the inspection of your installed solar system.
