The increasing demand for renewable energy sources has led to the widespread adoption of solar power as a clean and sustainable alternative to traditional energy sources. Ground-mount solar systems have gained popularity for their efficiency, flexibility, and easysolar maintenance among the different types of solar panels. In this article, we will explore the benefits and features of ground mount solar systems, including different installation methods, such as ballasted ground-mount solar racking, and compare them with other solar panel installations, such as pole-mounted solar and standard roof-mounted solar. By the end of this article, you will have a better understanding of ground mount solar systems and their suitability for various applications.
What is Ground Mount Solar System?
The ground mount solar systems consist of solar panels that are placed on the ground using a concrete foundation. These systems use the same photovoltaic panels as your normal rooftop solar systems. The main difference between rooftop and ground mount solar systems is that ground-mount solar systems are moveable in nature. This means that the adjustment of height and the angle of panels can be possible. The energy efficiency of residential ground-mount solar panels is slightly greater than that of rooftop solar panels. These panels have a slight edge over the rooftop solar panels. But the cost of ground-mounted solar panel installation is high due to the extra cost of labor and hardware parts.
How many Types of Ground Mounted Solar Racking Systems?
When it comes to solar panel installations, there are several options to consider, including pole-mounted solar, wall mount solar and standard ground-mounted solar systems. While both options involve installing solar panels, they usually differ in terms of their design, installation process, and suitability for different applications.
1. Standard Ground Mounted Solar System:
Traditional or standard ground mount solar systems installation is just like rooftop solar panels. The panels are mostly fitted into the racking system or frame. This frame composition involves steel and is quite moveable in nature. This will ensure increase solar absorption by the ground base solar panels. These solar panels operate in larger-scale solar energy projects such as utility-scale solar installations, as well as in residential and commercial applications where there is ample space available for solar panel installation. The standard ground mount solar systems come with two options. One is a concrete pier foundation and the second is a ballast system. A concrete pier technique involves drilling several holes into the ground. In these holes, the placement of numerous poles takes place. On top of these poles, solar panels are placed. Afterward, these holes are filled up with concrete hence giving this technique its signature name.
One of the main advantages of standard ground mount solar systems is that they are more cost-effective than pole-mounted solar panels. These panels require less material and are easier to install. They also provide easy access for maintenance, cleaning, and repairs, as their installation is at a convenient height above the ground.
2. Pole-Mounted Solar System:
Pole-mounted solar panels, as the name suggests, involve mounting solar panels on poles, which are anchored onto the ground. This pole can hold several solar panels at the same time. The maximum number of solar panels that a pole can hold is 24 panels. Pole-mount solar panels can be driven pier or Helical pile. A driven pier is basically a large pole driven into the ground using a special mechanical set. Afterward, a metallic frame placement takes place on top of the pole which in turn will hold the solar panels. In Helical piles instead of using concrete to hold the pole in place, a large screw is used. These screws keep the helical piles secure to the ground. While the need for the special machinery remains the same as the driven pier.
One of the main advantages of pole-mounted solar panels is that their installation takes place in areas with uneven terrain because pole adjustment can happen at different heights. They also provide greater flexibility in terms of positioning. These panels can be tilted to face the sun at the optimal angle for maximum energy production. Additionally, pole-mounted solar panels often operate in areas with high wind speeds as these panels are map out to withstand strong winds.
What are Some Benefits of the Ground Mount Solar Systems?
Ground-mounted solar panel systems provide a plethora of solar advantages for homeowners who seek to minimize their environmental impact while also saving money on energy bills.
1. Maximum Solar Energy Absorption:
Ground-mounted solar panel installation takes place on the ground. This provides the ability to position them at the optimal angle for maximum solar energy absorption. Unlike rooftop solar panels, whose solar light obstruction might happen due to shading from trees or other structures, Ground-mounted solar panels are position in a way to capture the most sunlight possible. This results in an increment in solar energy production.
2. Elimination of Rooftop Solar Panels:
Ground-mounted solar panel systems offer a viable solution for homeowners who prefer not to have solar panels on their rooftops. These systems installation can take place in a variety of locations, such as a nearby field or yard. This allows homeowners to reap the benefits of solar energy without the presence of panels on their roofs.
3. Expandability:
One of the key advantages of ground-mounted solar panel systems is their scalability. This makes them a flexible option for homeowners who are looking to gradually increase their use of solar energy over time.
4. Low Maintenance:
Ground-mounted solar panel systems generally require less solar maintenance compared to rooftop solar panels. With ground-mounted systems, there is no need to climb onto the roof to inspect or maintain the panels, reducing maintenance costs and ensuring optimal efficiency of the system.
5. Fire Hazard Mitigation:
Another advantage of ground-mounted solar panels is that they can help to minimize the risk of fire hazards associated with rooftop solar panels. In the event of a fire, firefighters may be hesitant to access a rooftop with solar panels installed. With ground-mounted systems, there is less risk of fire hazards, and emergency responders can easily access the system in case of an emergency.
How much does the Residential Ground-Mounted Solar Panel System Cost?
The cost of a residential ground-mounted solar panel system can vary significantly depending on various factors such as the size of the system, the solar panels brand and type of solar panels used, the type of mounting system, and the installation costs. Moreover, the average cost of a residential solar panel system in the US is $2.58 to $3.38 per watt. This means that a 5 kW system would cost approximately $12,550 before any incentives or federal tax credits. However, the actual cost can vary widely depending on location, the complexity of the installation, and other factors.
When it comes to ground-mounted solar panels specifically, there are additional costs associated with the mounting system. A ballasted ground-mount solar racking system, which uses weights to hold the solar panels in place. These can cost around $0.10-$0.15 per watt more than a standard ground-mount solar racking system. Carport and canopy-mounted solar panel systems can also be more expensive due to the additional structure required.
It is important to note that many states and local governments offer incentives, rebates, and tax credits to help offset the cost of installing solar panels. The federal government also offers a solar investment tax credit that can provide a 30% credit on the total cost of the solar panel system. These incentives can significantly reduce the upfront cost of installing a residential ground-mounted solar panel system.
