A free-standing solar array erected on the ground using either a solid metal frame or atop a single pole is a “ground-mounted solar system”. When a rooftop system is unavailable or not appropriate, ground-mounted systems might be used in their place.

 Both offer more advantages than using fossil fuels to generate your electrical demands. Solar panels are not appropriate for every roof. However, not all houses have the additional room required for ground-mounted panels.

Ground-Mounted Solar’s Advantages

Ground-mounted solar panels may be a better investment than rooftop panels, depending on your needs for space. Even if there are more advantages than disadvantages, each scenario is unique.

Nobody on Your Roof

Solar panels might not be able to be supported by your roof due to structural issues. Its appropriateness can be determined by a qualified contractor or inspector. Additionally, asphalt roofs require replacement every 10 to 15 years. Solar panel installations on your roof can also not look well to you, or perhaps your homeowner’s organization forbids them.

Seeing is Believing

Ground-mounted solar panels can be placed outside of your house’s or immediate yard’s line of sight if your lot is large enough for them. You can put ground-mounted solar panels on a property and then receive credit through a net metering program for the electricity those panels send into the electrical grid if you are fortunate enough to own a second property or are able to lease land nearby. (Community solar programs operate in this manner.)

Possibly More Effective

Solar panels that produce energy on a roof with a north-south orientation can still be supported, but the amount of solar radiation they get may prevent the panels from producing enough electricity to cover their costs. Ground-mounted devices can be installed without obstacles like chimneys, trees, or adjacent buildings, reducing the time to pay back.

Ground-mounted panels can be adjusted more easily than rooftop ones for the season or to accommodate a solar tracker that tracks the sun’s course throughout the day. A tracker-equipped ground-mounted system maybe 10% to 45% more effective than a rooftop solar array. 

Bifacial panels, which contain solar cells on the back of the panels that absorb light reflected off the ground or other hard surfaces, are more suitable for ground-mounted panels because of their greater height. Ground-mounted solar panels are less prone to experience heat accumulation, which lowers the efficiency of solar panels because air flows more easily around them than it does around rooftop solar panels.
